Very good find. I found one of those about 2 months ago. Apparently carrier must have gotten a hold of some bad sensors. I've never seen that on any other unit where the short is actually inside of the snap- disc and shorting because it's clamps onto copper. Pay attention guys. You can learn a lot from this channel. 😎👍
This is why i say you are #1 on RUclips. Bro, I don't know what's better. Your troubleshooting skills, your camera work, or listening to you say that you're "fixin" to fix something! Love you man!!! Good stuff. I always learn something new watching you
I have to say out of all the videos I've watched they're always informative and I have to say this was the best one yet I've always had problems with low voltage shorts but you really simplified it for me in this video on how you go about figuring it out
Good find. I have learned in this situation if it's a bdp heat pump to always look down inside unit for wire shorted to copper. So at beginning I was thinking that from experience. Our meter always tells us the culprit.
Like the nut driver, but I recommend the DeWalt 12v screwdriver can set the torque to prevent stripping the hole. A lot lighter and batteries last forever……
After testing the y,o,g and w wires the reds should’ve been separated and tested separately to see if the problem is going to the t-stat or going out to the condenser unit, but great job..
So I just learned something. I always thought that the defrost sensor was like a regular temp sensor that you would measure in ohms , so when the sensor reached a certain resistance value from temperature it would close and then when the board reached its time to check then it would allow the system to go into a defrost. So know I know that there is 24v going through that defrost temperature sensor.
On a defrost thermostat like that yes. It has to time out and get 24V on the other side of that defrost thermostat in order to go into defrost. Many newer ones use a sensor though.
Old style defrost like this one is "Time & Temp." With one single sensor that opens and closes. The newer style defrost is "Demand Defrost" with two thermistors, one sensing outdoor temperature and the other sensing coil temperature. And those sensors are measured with ohms resistance and compared to a ohm resistance/ temperature chart for proper readings. 😎👍
Is that is that a stackable set of magnetic nut driver ends you had on your impact gun? Pretty neat, who makes them? I haven’t seen a set that you can stack together like that…..
I kept trying to stick my head in help you look for short. Process of elimination little breaker is handy i get mine from when I gut a big rooftop. By the way where are you located?
I was guessing the reversing valve for the short. The whole time I was watching the screw you left on top of the outdoor unit taking the fan off but it turned out to be a bird turd 🤣🤷♂️🐦💩
Awesome videos enjoy watching your videos I have a HVAC company in Texas. Was wondering if you could tell me what brand is your screw chucks I’ve never seen one that goes from 1/4 to 3/8 thanks
If you look at his description (click the down arrow beside the title) he has links to his tools on Amazon. I think you're asking about the Malko flip bit 1/4 and 5/16 red and yellow.
I am confused about one thing. You pulled the thermostat off the wall and then jumped it to the float switch. How did that make it blow the fuse if the float switch had nothing to do with where the short was at which was the unit outside?
You should buy a tool called "short pro". It is a self resetting popper. It makes finding a short much easier and less time consuming. Watch a youtube video on how to use it and you will never use a popper again.
I have 34 years of HVAC service experience (AL11051), and would love to know where you got the resettable device that you replaced the 3 amp fuse with. I need one of those! Jeff
Among the white cotton fields of Georgia, it's the Climate Control truck, with HVAC Detective Sgt Curtice on his way to sleuth out the case of the blank thermostat. Oh no, it was a bad Chinese fuse; who would have guessed. 😎

I watched many HVAC techs work and diagnose a problem...but none of them have the knowlege that you have...yr #1 tech in my book very smart man.
Much appreciated

Love you man!!! Good stuff. I always learn something new watching you
So true 👍
I just learned a ton in this video. I’m 2 yrs in as a service tech in Myrtle Beach. Love the content
Thanks for watching
Great job Curtis. I've never run up on a shorted dft. Sometimes a shorted wire can be difficult to find!
Well… at least the capacitor was in a diamond plated box.
I had same situation last week, it chewed my ass before I found it, first time I come across one in 8 years, great job keep it up
Nice work, like how you cleaned it up better than you got it.
Good job Curtis.
Ah I remember my HVAC days, I design boat decks from home now. no more 8pm”hey we need you to run one more call 1.5hrs away”
I'm trying to run down a 24v short now on a heat pump. Its proven to be very elusive but I never checked the defrost thermostat. Thanks for the video
I am going to have to watch this many times to understand it.

Always fun chasing low voltage shorts!
Thanks again for the videos!

Great troubleshooting
Nice troubleshooting
Great video!
Good find
Love this video 🙌🏻 great job
Great diagnostic video!
Nice work
I get up at five pour myself a cuppa coffee and then go to HVAc Guy school for an hour before my day starts
Appreciate you for making these helpful videos
Good job troubleshooting.
This video was very helpful. Thanks
Glad it was helpful!
After testing the y,o,g and w wires the reds should’ve been separated and tested separately to see if the problem is going to the t-stat or going out to the condenser unit, but great job..
Nice job
I'm seeing it now... 2 years later. I know it's going to be a training 🚂 Day!
man you are the best I have the same problem I check the seleide coil rv my contactor but never the defrost coil I Lear today thanks
That was awesome 🙌
Great video
Thanks for the videos….🙏
It was very helpful
Always helpful,,💯

Where can I get that substitute fuse adaptor your using? Great video thanks for the content.
Thank you sir!
But basically, I like watching you, good stuff….👍
the short is always at the condenser, except when it isn't. 🤪 🤣
Why did you jump the r wire to the float switch? Thanks for any help
Is that is that a stackable set of magnetic nut driver ends you had on your impact gun? Pretty neat, who makes them? I haven’t seen a set that you can stack together like that…..
good thing no bees in disconnect LUCKY HVAC GUY 😁😁😁😁😁

I was guessing the reversing valve for the short. The whole time I was watching the screw you left on top of the outdoor unit taking the fan off but it turned out to be a bird turd 🤣🤷♂️🐦💩
Where can I buy the thing you were using to showing the fuse blowing like a gfci tester? I need one
I got that at United Refrigeration
@@HVACGUY do you have a name for the part I have united near me
Great video
What kind of tablet do you use for drain line.
Can’t tell you the name brand. Sold at United
@@HVACGUY does it work for drain clogged

@@bw1841 yea it’s malco but other one is Klein which goes 1/4 5/16 & 3/8 and other more on one bit
I think you’re talking about the Klein flip bit

Float was still connected to both reds

Go to Amazon they sell it for cheap good to have it
Defrost thermostat NC or NO?
That’s a lot of work/time, what would you charge for that…?
No way you didn’t demand a condenser cleaning and tell them to get rid of that tree
👍
Last one I had it was chewed up by rats.
guy wear kn 95 mask
I never go in a attic or cross space without a dust mask
It would be good if you communicate, a little more, even though, it’s a job, I get it, but you’re making money on us watching you, as well…. Thanks

you need some N95 masks which you can get for free at Walmart as you walk in..courtesy of Brandon..lol If not there, check the pharmacies. All free..
