I cannot express how thankful I am to you. My system shut down in NC during this 100° heat wave. Turned out the system in the attic was filled with water. I sucked out the water with a shop vacuum and it fired back up again with no issues. Tomorrow I will cut the evap pvc pipe, clear it out amd use pvc unions to reconnect it. Sir, you saved me a fortune. Thank you so much!!!!!!!!!!!
Never would've guessed something as simple as the condensate safety switch. Used my shop vac to remove the water from the pan and the unit instantly kicked on! This video was very helpful. Thanks! 👍👍
Thank you AC Service Tech and @soccerplayahershey. Had issue with thermostat not being on, replaced battery and still nothing. Water in pan was at the top and could see damp areas nearby. Wasn’t comfortable around the system especially with water and electricity but after reading @soccerplayahershey’s comment I went down, turned circuits off and shop vac’d the water out. Success! Thank you so much, I have air flowing on this hot day in August. Just to show a woman in her late 60’s can make things happen. Very happy.
Thank you for the tutorial, my A/C went out on one of those 100 degree days, my HVAC guy was out of town and I would of had to wait three days til he got back. I don't trust just call any repair services from my experiences with dishonest or over charging, so I stick with one company I trust, anyways I changed my capacitor on condenser, still didn't work, when you mentioned checking the thermostat by jumping the connectors nothing happened, then I went up into the attic (100+) I found the condensation safety switch in the drain pan was a little tweaked, realigned it and cool air was back, thank you very much you saved me a lot of money and being miserable for days in 100+ temps!!!!!
Oh my gosh. Thank you! I had plumbers in my attic a few days before I noticed my AC wasn't working. Your advice to check for a loose door was spot on. I'm sure they bumped it loose. You saved me so much frustration and a service call.
Thk you bud followed all ur tips and tracked it down,wife was weed eating ,she hit the two thin wires the red and white,it stripped them both and both copper wires were touching,checked fuse and it was burned.Thks again bud for making me look like a geniuos to my kids.❤❤❤
I couldn’t find a video to where the inside blower and the outside unit wasn’t working and I almost didn’t watch this video but I’m so glad I did, I started by using a jumper wire at the thermostat and nothing so I checked the control board and remembered I use to see a green led light on the board, so I pulled the 5amp fuse and BINGO! I already had an extra fuse on hand. Thanks for the video!
Yo I've been stressing about my condenser shutting off for the past 24 hours. We had my gf's mom over yesterday for a labor day grill and the ac stopped working! I panicked and spent some time in the heat trying to figure out what could be wrong. i woke up today, hot, and worried that I would have to replace my entire unit for thousands of dollars...was about to call an AC company but decided to watch this video. When I got to the part about replacing the batteries in the thermostat I scoffed, but figured its worth a shot at least. There's usually an indicator that says low battery, but since you convinced me to try it, I changed them despite the lack of any indication of them being low. Imagine my relief and joy when I walked outside to a spinning fan in my condenser. Thank you sir, you probably just saved me from someone trying to scam me into buying a whole new unit. I've been laughing with relief since. Thanks for the video!
The tip about the switch was super helpful. Our A/C condenser dumps water into our sump. When I replaced the sump pump, I must have pushed water back into the system causing the switch to trigger. Although the switch is different and doesn’t have a reset, I was able to twist the switch allowing the water to drain and move back to the original position. The A/C started right up. Thanks for the great video!
Watching from Toronto, you just saved me tons of money, did the trouble shooting turns out it was my thermostat wire that’s bad. I jumped it directly from my furnace and everything works ! Thanks for your help!
Number 1 problem for ac system not running after 30 years in Hvac business is condensing unit capacitor bad . 8 out of 10 summer service calls are capacitor .
For me it was the fuse. It was 3a and I had a 3a. Started right up. So many thanks. And really liked how thorough it was. I have found and replaced capacitors before but not a fuse.
After spending figure why my smart doesn’t power. After seeing your video, fixed it. I love ppl like you making video like this for ppl like me no a handing man
Got a new Smart Thermostat and after installing everything went black, after viewing your video I was able to fix it myself. Was a $4 3amp fuse. Good info you have provided. Thank you
Excellent instructional video. The internal low voltage fuse was blown due to a rookie mistake on my part. The condensate pump wasn't working so I swapped it out without killing power to the entire unit (I did unplug the pump). Somehow, power found its way to the LV fuse & killed power to the main board. Now I have spare fuses but won't make that mistake again.
Great informative video very much appreciated. My Tran AC stopped working a few days ago in the middle of high heat. Since I had changed the capacitor before, I rechecked the capacitor and found it to be the correct value. Checked the low voltage and found out that 27V is missing. It was challenging to find the source and it happened to be the safety switch on the swamp pump!!
You are an amazing human being! We're about to get a heat wave starting tomorrow and lost power to the thermostat. Thank you so much for making this video!
With my situation, I called the light company and come to find out a wire came aloose at the transformer. Now it runs perfect, and I think the Lord for that. Free service.
You're videos are awesome! You explain everything thoroughly, but without getting long winded. I also love that you explain which terminals to test with the multimeter. Great job and thank you for your help!
Thank you for your suggestion on the 3 amp. My fiance didn't think about it when he was trying to get our AC to work. Your video is so very much appreciated.
Excellent video, I remember #9, fuse inside AC box, my repair friend left another fuse, but I have AC guy coming over. I'll save your video for next time
Thanks for sharing so much helpful information. We’re having trouble with our condensate line and excess condensation dripping from the air handler - We’ve watched several of your videos and noticed a condensate pump shown in this one. Do you have a video about the pump you are using and how you install it? Thanks!
You saved me a bunch of money! It only cost me $1 for a 3 amp fuse once my AC went out. It went out because I wired the thermostat wrong but it at least is fixed. Thank You!
I have a question I diagnosed my AC system from watching this Video. and figured out. It’s the thermostat. My system is combo AC & Heat. I jumped the Red & Yellow wire together. So now the AC and the blower are working but the AC compressor is not turning on. As to before I jumped the 2 wires together the AC unit would not turn on at all. So I am assuming that based on the video that I need to jump Red Yellow Orange and green together?? Any advice would be greatly appreciated
Thank you for the tips mine was the metal door button wasn't pushing all the way in I taped it put door back on and now sitting in a nice cool house ty so much saved so much money calling someone out here
Looling for suggestion: AC unit went out and the capacitor was changed on the first service visit. Was told need a new unit but Choice warranty approved to change the compressor instead. Ok, compressor was changed yesterday and house back cooling. Here's the issue, the air filter needed to be changed so I head up to attic (turned off AC at thermostat) and changed the filter. Turn thermostat back on to cool, and the AC unit outside never kicked on. Checked breaker and everything and still does not come on. Any suggestions on what it could be? Serviceman cannot come back out until next week. 😩 Thanks in advance,
Just to mention I learned about the word tau , and the capacitor charges up and then discharges in 5 tau. ! 1 tau. 2. Tau. 3 tau. 4. Tau. and 5 tau The capacitor will start a motor up in 5 tau then the contact will close if I remember really well ! The capacitor and contact combination are a parallel combination in series with one leg of the motor or one hot wire!
Fuse , breaker ,capacitor ,contactor ,thermostat are some issues or if it’s a heat pump low charge , good stuff I was just going to say common wire too
Both the inside unit and outside unit are running just fine. Changed the filters, cleaned the coils, replaced the batteries in the thermostat and still no luck
If the condensate line is clogged and triggers the shut off, will just clearing the clog be enough? Or do you need to do something to reset the trigger switch? Mine was clogged, I cleared it, poured water down the drain and it stays clear, but the AC won't come back on. Originally, I happened to be walking by the hall closet where the unit is (1969 house) and I heard some clicking, shortly after the AC went off. So I checked the Safe-T-Switch, which I normally pour vinegar down 4 times a year - but hadn't in at least 3 years.
My ac unit at this rental looks older than anything you've showed. Their is a pvp pipe coming out, but it's just ran down the side, and then parallel to the ground, down to a drain in my basement. Not scorching yet but it is almost 80 and ac unit won't work. Landlord said he will get someone out here tomorrow. Worst part is I absolutely can't sleep when I'm hot. I keep it around 65-67 when I'm going to sleep. 😪
What would be common problems for BOTH indoor and outdoor units not running? I turned air off but forced fan “on” and it doesn’t blow. Outdoor unit never kicks on. Does the thermostat directly control outdoor unit or does that signal pass through the indoor unit first? Meaning, can a problem with the indoor unit (like a condensate drain) also cause the outdoor unit to not come on?
Oh the nest the number #1 issue with those are the common wires not being connected at the time thermostat or at the air handler or period due off factory charge . I always check to see if common is connected, not recommended but I grab a little piece of wire and barely touch r and c to see a little spark (ounce again not recommended) keeps you from going in air handler attic up stairs etc …. You know common is connected SO I then hook it to the thermostat or connect it at the board air handler etc..
A couple weeks ago, when I turned my central air on, it wasn’t cooling. I had forgotten to take the cover off the unit. Now I’m finding that it has stopped working. I changed the batteries and circuit breakers and they’re all good but unable to check the rest. Hard to do with no man around. 😂
I've gone through these potential problems and can't find out why the unit suddenly stopped. The only anomaly I found was all lights are out on my Honeywell HZ322 controller and it's getting power. Will a unit not start if the zone controller is dead?
Hi! Thanks for this video. In the past couple of months, sometimes when we push the thermostat down a few degrees, it won’t trigger the on. It’ll flash “cool on” but the AC doesn’t turn on. I then turn off the system and then reset the circuit breaker. When I turn it on again it starts working. It doesn’t appear to be a condensate drain line problem as water isn’t backed up. Also, the unit is only 2 years old, got it installed a couple of years ago. Do you have a sense of what this could be? I don’t understand why it always works after resetting the circuit breaker for AC. (The breaker doesn’t appear to be tripped when I reset.)
My daughters LG air conditioner, after being cleaned by a technician recently, started to work differently after he left, e.g. when I turned on the inside unit, the fan blows at full capacity and then the inside unit shuts down. The outside motor (compressor) doesn't kick in at all when this is happening, and then the inside unit that is blowing the fan at full speed shuts off within a minute. I rang the technician and he said that he was willing to come back to have a look at it and of course take my left arm for the problem he caused in my opinion, because it was working fine before he pulled it apart to clean it, so I told him to FO in the nicest possible way. I am not in anyway a technical kind of guy, but I think I can change the capacitor by myself, if that is what it is. I would appreciate any assistance that anyone reading this can provide me with, e.g. do you think it is anything else apart from the capacitor. The outside motor (compressor) kicks in after about half a dozen attempts at turning it on and off, when the inside unit was blowing air at full speed, so it sounds to me like it is the capacitor, as that is what gives the compressor that extra kick from videos that I have seen. Appreciate all assistance in advance.
It’s annoying because if I knew how to fix it, I would. But I have to wait in the middle of the night three hours for someone to come and do it, and now I’m going to go into work tomorrow not having had any sleep and being cranky because I was hot and anxious all night.
Update: I checked the float switch after watching this and that indeed was the problem. I was just worried I wouldn’t have the right tools, I would break something, or I would electrocute myself. But you made me feel safe once I understood what everything was. And I just used a towel repeatedly to soak up the water that was full in there. Thank you!
Pressure Limit Switch is tripping. (Located outside on A/C unit). Fan will not move on its own unless knocked with a screwdriver. Unit itself was very dirty. Smaller diameter copper pipe was HOT to touch.
I cannot express how thankful I am to you. My system shut down in NC during this 100° heat wave. Turned out the system in the attic was filled with water.

Problem #5, was my situation. Your video saved me a service call and one day of 95 degree weather. Thank you very much.
That lightning bolt scared the crap out of me 😅 great video for people learning simple diagnostics on an AC!
Best most complete video on HVAC troubleshooting by far!!!
Thank you!
Very informative and professional!
Thank you for the 10 tips I just fixed my Ac with your help.

Number 1 problem for ac system not running after 30 years in Hvac business is condensing unit capacitor bad . 8 out of 10 summer service calls are capacitor .
Capacitor replacement will become obsolete in the coming years.
@@July4.1776 Variable speed control boards will be the new capacitor for ac failures
@@billy5032 yeah, and if they fail as often as a capacitor then someone is bound to make a lot of money.
We’ve been having a lot of clogged drains and condenser fan motors here in TX, and fuses that pop on residential Geothermal package units
Efficiency up ,reliability down ,repair expense up ,electric bill down.
Thank you for the time you spend every day making these videos
For me it was the fuse. It was 3a and I had a 3a. Started right up. So many thanks. And really liked how thorough it was. I have found and replaced capacitors before but not a fuse.
Mine was problem 4!
Thank you , saved me some money & time!
It was 93 degrees outside in Texas today definitely needed that Cold AC
Problem number 4 was mine, and thank you for educating me on that because you saved us a lot of money.
After spending figure why my smart doesn’t power. After seeing your video, fixed it. I love ppl like you making video like this for ppl like me no a handing man
Very informative, not generic. I learn things that others don't say or go into more detail about. Thank you! and Kudos.
Glad it was helpful!

it was the purple fuse for me. it only cost 5 bucks and saved me a few hundred. Thanks man.
Thank you!! My son put a broom in the closet and shut off the light switch. I didnt even know it was in there! Appreciate this video🤗
Great video! I had these symptoms and using the jumper wire technique to bypass the thermostat revealed it was the problem!
Your videos are really saving a lot of people, a lot of money! Thank you!
Thank you so much. Hooked up a shop vac to the outside discharge pvc line. Lots of gunk in there. Got it working pretty quickly after that.
Thank you.
Glad it helped!!

Wow, thank you for your kind words and for watching our content!
My issue was the little 3 amp fuse which I figured out thanks to you but only after I replaced the capacitor. Thank you!
Thank you for your suggestion on the 3 amp. My fiance didn't think about it when he was trying to get our AC to work. Your video is so very much appreciated.
Although my problem was a bad contactor, this video helped me go through the troubleshooting procedures to narrow the problem. Thanks for the help.

Thanks for watching!
What kind of multimeter would you recommend for testing the capacitor and other AC components?
Thank you for the video you save my life I live in florida and my ac went down at the middle of the night you save my life thank you so much

This video helped me to solve my problem. Problem number one was the solution. Thank you very much
On a electric/gas unit..
Does the furnace need to have propane going to it in order for the ac to work in the summer time?
Great video that has helped me twice today. Thank you for posting this!
Thanks man! Tip number one solve my problem. I really appreciate the video!
Videos are always well done and informative. Great information for seasoned techs that want to refresh or new guys looking to learn.

Would you recommend changing capacitors or fan motors based on time (21 years) as a preventive measure?
Check MFD on the capacitor. That’s how you test to see how what they are currently running at vs what they are rated for.
My ac unit at this rental looks older than anything you've showed. Their is a pvp pipe coming out, but it's just ran down the side, and then parallel to the ground, down to a drain in my basement. Not scorching yet but it is almost 80 and ac unit won't work. Landlord said he will get someone out here tomorrow. Worst part is I absolutely can't sleep when I'm hot. I keep it around 65-67 when I'm going to sleep. 😪
You just saved me a chunk of change! Thank you 🙏🏼
Any plans for a book in electrical troubleshooting?
Appreciate your content !
Thanks I follow all the the video and check every step and the door from rhe unit was a little open .
Fit it... thanks
thank you for your expertise AC trouble shooting knowledge, I was able to resolve the problem and feel like I shaved some money,
You just saved me from having to call the hvac tech. Blessings upon you and your family. It was the thermostat, not the outdoor unit. Thank you.
As usual, the most clear concise videos. Great info. Thanks!
Thx. Safety was tripped
Bad control unit, thank you so much. Bout to go crazy trying to figure it out!
Jumping the thermostat points revealed the flaw in my system. Thank you!!!! Subscribed w/notifications
What would be common problems for BOTH indoor and outdoor units not running? I turned air off but forced fan “on” and it doesn’t blow. Outdoor unit never kicks on.
Does the thermostat directly control outdoor unit or does that signal pass through the indoor unit first? Meaning, can a problem with the indoor unit (like a condensate drain) also cause the outdoor unit to not come on?
When your pregnant gf flips the emergency switch and enters into panic mode when the AC doesnt turn on 😂 this was gold! Thank you sir
Thank you so much for your help my problem bad phase in the thermostat
Thanks man
I’m here wondering how to find my AC control panel? I live in Phoenix in a condo, there is no indoor furnace. AC unit is on the roof
Your videos very informative. I have a bad 3amp fuse. Thank you
You are amazing!! Thank you!! I wish i would see your video before my Ac. Broken.
Thank goodness for you i cannot even begin to thank you god bless you
Thanks for the great explanation of possible issues.
Oh the nest the number #1 issue with those are the common wires not being connected at the time thermostat or at the air handler or period due off factory charge . I always check to see if common is connected, not recommended but I grab a little piece of wire and barely touch r and c to see a little spark (ounce again not recommended) keeps you from going in air handler attic up stairs etc …. You know common is connected SO I then hook it to the thermostat or connect it at the board air handler etc..
Thank you so much man for your videos
What type of wire are you using to jump
You did not discuss about bad stepdown transfomer 24 v and what components affected.
Thank you so much. I followed the video and fixed it which was problem #3
Great video! Thank you!
Went on a two hour drive once just to turn on switch. Inspected unit found nothing wrong was not very happy about that call lol
Haha I hear about those a lot. I’m finishing up HVAC school currently. But hey it’s still $$ in your pocket. (Or your company’s lol)
That's free money.
3 hours or 5 hours depending how you charge.
I would love a port 2 port OT call like that. Haha
Thank you so much! Fuse went out.
A couple weeks ago, when I turned my central air on, it wasn’t cooling. I had forgotten to take the cover off the unit. Now I’m finding that it has stopped working. I changed the batteries and circuit breakers and they’re all good but unable to check the rest. Hard to do with no man around. 😂
Thank you so much sir it was the float switch worked instantly
8:30 I tested a capacitor last year and it tested good but when I shook it, I could hear it. It was bad, but why? Thanks for the awesome video!
Oscilloscopes are really necessary when diagnosing
Hi voltage alternating current motors!
I've gone through these potential problems and can't find out why the unit suddenly stopped. The only anomaly I found was all lights are out on my Honeywell HZ322 controller and it's getting power. Will a unit not start if the zone controller is dead?
Thank you!!! For the info saved my Easter with this video you sir are my hero!!!
You helped loads! Thanks!
Thanks so much for your information. Worked like a charm in my case and I'm a true novice.
Excellent!
Hi! Thanks for this video. In the past couple of months, sometimes when we push the thermostat down a few degrees, it won’t trigger the on. It’ll flash “cool on” but the AC doesn’t turn on. I then turn off the system and then reset the circuit breaker. When I turn it on again it starts working. It doesn’t appear to be a condensate drain line problem as water isn’t backed up. Also, the unit is only 2 years old, got it installed a couple of years ago. Do you have a sense of what this could be? I don’t understand why it always works after resetting the circuit breaker for AC. (The breaker doesn’t appear to be tripped when I reset.)
My daughters LG air conditioner, after being cleaned by a technician recently, started to work differently after he left, e.g. when I turned on the inside unit, the fan blows at full capacity and then the inside unit shuts down. The outside motor (compressor) doesn't kick in at all when this is happening, and then the inside unit that is blowing the fan at full speed shuts off within a minute. I rang the technician and he said that he was willing to come back to have a look at it and of course take my left arm for the problem he caused in my opinion, because it was working fine before he pulled it apart to clean it, so I told him to FO in the nicest possible way. I am not in anyway a technical kind of guy, but I think I can change the capacitor by myself, if that is what it is. I would appreciate any assistance that anyone reading this can provide me with, e.g. do you think it is anything else apart from the capacitor. The outside motor (compressor) kicks in after about half a dozen attempts at turning it on and off, when the inside unit was blowing air at full speed, so it sounds to me like it is the capacitor, as that is what gives the compressor that extra kick from videos that I have seen. Appreciate all assistance in advance.
Newer Allied air hamdlers/furnaces have a 3amp circuit breaker, located on the door switch instead of a fuse on the board.
Thanks for video it's really helpful.
Glad it was helpful!
THANK YOU!
It’s annoying because if I knew how to fix it, I would. But I have to wait in the middle of the night three hours for someone to come and do it, and now I’m going to go into work tomorrow not having had any sleep and being cranky because I was hot and anxious all night.
Update: I checked the float switch after watching this and that indeed was the problem. I was just worried I wouldn’t have the right tools, I would break something, or I would electrocute myself. But you made me feel safe once I understood what everything was. And I just used a towel repeatedly to soak up the water that was full in there. Thank you!
Pressure Limit Switch is tripping. (Located outside on A/C unit). Fan will not move on its own unless knocked with a screwdriver. Unit itself was very dirty. Smaller diameter copper pipe was HOT to touch.
Awesome video!
