HVAC Basics: First - Mini Fridge Refrigerator Troubleshooting Part 1 of 2
HTML-код
- Опубликовано: 1 окт 2024
- In this video we discuss some of the basic for trouble shooting a mini fridge refrigeration system. Testing for shorted ground, testing the thermostat operation and compressor running load amps (RLA) and locked rotor amps (LRA) are discussed. This is only half of the lesson and part two will be uploaded at a later time.
The only thing I thought this entire video is this guy is one hell of a teacher. The world needs more people like this. Very informative. Asking the students questions to keep them engaged. Asking questions over previous lessons for memory through repetition and engaging the students. This was 10/10
I thought so, too. He's teaching them to think on their feet, which is what's needed in that line of work. I wonder if he was an instructor in the military (?)
Bra I had a teacher like this, and she was cool and all, but like trust me asking questions to previous classes and stuff we’ve done many times, I feel the students and their awkward shuffle silence, cause it’s like, you gave a hint, but also, we’ve done it so much we forget it’s a procedure or formula or whatever, and it becomes more like second nature rather than having a name, so being asked to name it is hard
Yes he is,.. who the hell is he, I wish my teachers were like this guy for damn sure!!!! There is a clear difference in a quality teacher, and well,... the opposite. He's no fuss matter of fact, down and basics, simplicity all teacher. Just damn good.!!
Agreed 3 mins in learned that 80% all issues are electrical
I know. It is so cool. I'm not even in a related course but I got something out of this. 😅
I'm a 64 year-old woman and never knew I'd be interested in something like this. That's the sign of a truly skilled teacher -- engaging, animated enough to get the students excited about learning. Those students are lucky to have such a great teacher and mentor!
fizzy0ne1 yes indee D
A. This guy is an amazing teacher.
B. This guy sounds like Matthew McConaughey. 😆
Lol alright alright
Those students are fortunate to have a instructor like him. Great video thank you.
+Ron White thanks for saying that. Very nice of you.
I panicked when this guys literal first example of how something could go wrong was exactly what I did to break my fridge xD
Me too💀
Within the first 30secs of the video I was thinking to myself “ah see this is the teacher you want to have”.
I was fortunate enough to have an excellent HVAC teacher that included and engaged students similarly to this teacher, and it made all the difference to the level of skill we were able to then directly apply, & use confidently and successfully in the real-world workplace environment.
This is the example for all teachers that teach hands-on technical/mechanical/industrial classes such as this one. You’ll know it you’ve got one at your school because their class registration will fill up most quickly after registration-opening. Try to get in that one.
Thank you for your kind words.
he has talent to teach
Thank tecnico, very nice of you to say. Thanks for watching.
edisonhvac I'm using the probes on my multimeter because I don't have a clamp, the little refrigerator I'm looking at is rated at .8 amps and at the Wire going to the overload switch I'm getting 1.1 amps do you think that is the compressor locked up?
tecnico agree, I like his matter of fact style! Good teacher.
@@ChiefHoover .8 amps +/- 10% . 1.1 is not unreasonable.
Yea he does
I Love the way you teach, first year in school and boy those guys are so lucky to have you.
Where is this a s school located? The teacher really knows his stuff and is a wonderful instructor.

A shop teacher that still has all ten fingers. You don’t see that everyday.
35 years old … I needed this teacher growing up
Really great teacher! Love his technique and hands on experience to learn what needs! Very impressed! Makes me want to take an HVAC course!
Returning to this video, to let people know. His explanation helped me to resolve a similar issue with my refrigerator. Thanks a million to the Wonderful Teacher!! 👍🏼👍🏼🙏🏼🙏🏼
My mini fridge quit working last year and I was just about to go buy a new one. Thanks to great instructors like this I won't have to. Great video 👍
Do mini fridges not have any fans moving air around? I feel like they would mold food quickly with our air circulating
We’re you able to fix yours? I’m trying to see if I could fix mine myself too.
@@sillybears4673 Many fridges and freezers don’t have fans, only frost free models require fans for air circulation.
I have a mini fridge that has a working fan and the lights work in the fridge but it isn’t cooling, the thermostat is set to max cool as well, no oil leaking, can anyone help me out?
He sounds like Mathew mcanothy
When you teach that way you KNOW you have a passion for it!
Agreed
This guy looks like Johnny Knoxville's smarter brother....
I have watched dozens and dozens of you tube DIY. Never have I seen someone so thorough, easy on the ears and eyes, and explain what, where, when, why and how so simply that I actually get it!
Wow. This is a teacher.
You are an awesome shop teacher. I would have loved to have had you in my shop classes!
This is not what I was searching for, but glad I found it. I agree 100% with Ricky Stubblefields' comment. I watched the entire video gave a big .👍 & subscribed. Will be watching more of this channel.
Stay safe, Joe Z
Thanks!
@@edisonhvac 👍
This guy is an amazing teacher. I'd love to see him do some more instructional videos exactly like he did this one.
Wow. Why does society tell kids, the only way to succeed in life is to go college. Trait schools are awesome. Learn a skill.
Awesome teacher!!! This guy loves what he does and deserves a major raise!!! These kids are blessed to be taught like this! A+ Teacher
He is a pretty good, very informative teacher. He also sounds a lot like Matthew McConaughey 😀😊
Loved your video and teaching style. The world needs more teachers like you! Cheers! What do you do for a mini fridge that is continuously running and not cooling like it use to?
This man is a genuinely wants his students to succeed ..well done
I hate these things, for the very reason that they bond the condenser coil to the inside of the back panel. It reduces condenser efficiency and is harder on the system as a whole. They do the same thing to the condensers on newer residential chest freezers.
can u guys fix my fridge 😭 lmao
I just got me a little mini-fridge and I want to know how long it takes to get cold. There's this lady living with me and her children keep eating my food. I come out of work and half of my food is gone.
Tell them to piss off!!!
I don’t know how I got to this video; I have zero interest in HVAC, but I watched quite a bit of it because your teaching style is incredibly captivating, efficient, and personable. I wish you the best
And here you are! I’d be interested to know how you landed here. Thanks for the kind words and for leaving the comment. Best to you as well.
@@edisonhvac Of course, thank you for the well wishes. It was on my RUclips recommended homepage actually! I think that means all the positive engagement on your videos is starting to cause your videos to be recommended to a wider audience
I swear if my teachers were like this who cares and really gets the students involved with clear and a real simple explanation with plenty of examples, I would of succeeded instead of screwing off and relearn simple physics later in life "myself". Anyways great video and thank you for the enlightenment =]
Where's Part 2 of this great video? I agree with other comments about this teachers techniques and his approach in teaching his student's. But now I am thirsty for Part 2 and I have searched, but can't find it. Has anyone seen part 2? If it's a yes, please let me know where to view it at. Thanks
Thank you for your videos, they are a great help to learning HVAC/R. It was a great help and a great educational experience in total. I especially loved seeing the "Annie". That being said, I believe you misdiagnosed this refrigerator. Happens sometimes when we are in front of an audience and have already formed a hypothesis. It's still a great educational video. I didn't see you test the start components. Near the end of part 1 you showed the schematic confirming my suspicions. The schematic shows this is an RSIR (Resistor Start Induction Run) compressor with no capacitors. It uses a PTC to provide Start winding current and then, as the resistance increases, decrease the Start winding current to prevent it burning out. It is probably a 4.7 ohm PTC. I found this video while attempting to repair a slighly larger mini-fridge that had the same symptoms. The compressor got very hot and hummed but wouldn't cool. I believe it was failing to start because of a failed PTC and just sat there with current flowing through the Run winding but not rotating, until the Thermal Overload cut it off. The cycle repeated when ever it cooled off enough to reset. It was drawing about 9 amps while sitting and humming with an LRA rating of 11 amps. I checked the PTC device and was reading about 60 ohms while it was supposed to be 4.7 ohms when cold. I disassembled it and found a coin shaped PTC sandwiched between 2 flat spring contacts. One side showed signs of arcing on the PTC disc and its contact. I sanded/scraped the PTC and the contact and got the PTC down to 11 ohms and reading 9 ohms when the device was reassembled. I reinstalled it to check my hypothesis. The mini-fridge started right up and is showing its rated RLA of 1.3 amps. The new replacement should arrive in 2 days but the fridge is still running.
Again, thank you for your videos. They have been a great help in my HVAC/R education and will remain a wonderful resource. I hope you and your family are doing well!
Your one of only a few to catch that. It doesn’t even have a cap on that unit. Someone else mentioned it but didn’t go into the detail you did and I’d like to say thanks. Appreciate you leaving this comment for others to see. Thanks for watching.
You posted this a year ago, but I wanted to respond to let you know that I tried exactly what you just said… sanding the “dime” inside the PTC… and it worked for me. Found a non-working mini fridge on the side of the road, and that trick made it work, 100% confirmed. My only concern is, I also sanded away what looked like some kind of special coating. Not sure if that will lead to a future problem.
I thought that evaporator thingy was meant to be a freezer. I just bought one and it said fridge freezer !!
Well I just snitched on myself lmaooo I impulsively started jabbing at the giant chunk of ice that was surrounding the freezer part of my fridge with a kitchen knife and then it started to make a hissing sound and also let out a faint smell of gas I read the warning on the door to the freezer and it said explosive and flammable I immediately unplugged it 😭
Had to subscribe right away out of respect for what a great teacher this guy is. I had a few teachers like him growing up; they're worth their weight in gold.
Thanks
Who else loves feeling the compressor when it's doing it thing?
The hum and scent of data centers was always a favorite
My compressor runs, I hear Freon moving but isn’t cold. Can’t figure it out
Question, small 1.6cu ft fridge new, small compressor, on colder setting turns on every 15 minutes and runs for five minutes… is this normal? Temp about 34-36 degrees open space air in fridge temp gauge door closed…
Could be. Stays cold and cycling is a good thing. As long as the compressor doesn’t overheat all is good
We need this type of education in High Schools.
Would help a lot with youth mental health. These trades give us a purpose and helps us with growth in patience and problem solving.
One heck of a professor.
Trade teachers or really any jobs with active/on the job training are always way more engaging. Anything where you can be shown in person how to and the teacher/trainer is really invested in making you successful are always the best. Feels a lot more "real world"
Sir, where do I purchase the meter your using??
Thanks, from Joe..
Turn the subtitles on an go to minute 13:10 and maybe tou will read something funny 😂😂
This is a great informative video for the diyers of the world
Wouldn’t be an electrical class if they swept up they’re mess aye😂
Yeah I'm here 11/19/2021 love from Visalia CA
Thanks for this video .
My fridge when I plug in the wire the fridge light inside the fridge working but the fridge compressor and the little cooling fan the one next to the copmressoer not running ?
Did you check the Thermostat?
This video saved me a lot of trouble and money. My wine cooler repair was cost was under $7.50. Wish this guy was here to share a glass of chilled wine.
😀
Thank you!
He sounds like Matthew McConaughey 😎
It was working and I cleaned it and everything and then all the sudden
This guy made me wanna learn Hvac to be honest, obviously this is the simplest introductory, but growing up and being an adult showed me I should be able to fix my fridge or a/c, do my breaks change my own oil, not needing a specific technician and paying someone hundreds of dollars.
Yeah he demos, lecture, and hands on you can't ask for anything better! Simply the best at what he do!
Schools need Teachers like this!!! Very informative!
Thank you again for teaching these kids. I just love watching it
This teacher is going to make me switch from welding program to Hvac
Great video, great teacher! My only criticism is that I wouldn't be leaning on the top of the metal fridge with one arm and hand while poking around inside it with the other when plugged in. I was taught to put one hand in my hip pocket whilst poking around live circuits, thus preventing a possibly deadly circuit through my heart.
Mine looks just like that different brand name but same inside luck. I want to get a drink in the garage because I was so hot and sweaty and my drinks were all warm so I checked the breaker just fine I had it set on six it won’t go no further so I turned it down to one and turned it back up to six and boom sparks flew is this fixable or throwable
I think when you let the sparks out it’s time to get a new one. 😁 Thanks.
@@edisonhvac I did. Lol ty
How to stop the Majic Chief mini 2.5 in my Semi from making a rattling noise when I am driving?
Thank you, very helpful and interesting.
Thanks for the comment. Spread the word😊
This video took me straight back to my days in vo-tech school. Had an automotive teacher who acted and taught so much like this guy. I wish i could go back and be a young fledgling again.
Right on. Thanks.
I'm over here yelling all the answers because they don't say anything lol
Thanks for your participation 🙂
Bog props and much respect to this teacher. I am inspired to learn more of these skills simply due to his instruction and encouragement. His confidence and intuitive real time teaching is high level. Whomever you young folks are that learned from him over the years, you should be proud and honored to have had such a teacher.
P.S. this helped me fix a free mini fridge. Thnx
Peace N Love
Teachers like this make me wanna go back to school 😂 perfect .
oh goodness I am LUCKY! This looks like the exact mini fridge I'm dealing with
Fix it?
@@edisonhvacindeed! 20+ year poker group is enjoying not having to get a new one and I'm looking handy as a concierge
Thanks to you and this video
I recently had to patch a hole in the freezer tray how hard is it to refill the freon on the mini fridges everything works on it just doesn't get cold since the freon leaked out
Needs the refrigerant for sure
@@edisonhvac is it hard to use the bullet punch an attachment to refill freon
Thankyou I was able to fix my mini fridge just by turning the knob off and back on. 🙌🏼 thought I needed to buy a new one.
Thanks for your help! 😊
Love this vid. We need more educator like this! Looking around to see why my beverage fridge not cooling. Compressor not running. Change the relay but didn’t help and the overload make a bit of shaking noise. It is that you think?
I pierced the tray,frion shot out, can I fix w JB weld
Maybe
7:54
OMG. He is having all these newbies just stick their hands into the back of live refrigerator, with wires exposed, and apparently overload tripping.
Sure it can be done safely if you know what you are doing, but there needs to be a bit of instruction on that; gloves maybe.
That notwithstanding, the teacher is very good, and knows his stuff.
Best learning video I've ever seen. It brought back all the simple stuff that I thought I didn't need in high school.
Great style and so informative. Loved the way you teach. So practical and logical in your approach. Thank you for filming and sharing your knowledge with us AND the future tradespeople of the world.
I picked up one just like this for $10 at garage sale. Works great, however I want to use in my Jeep for camping with an inverter. I would prefer the door to open on top. Easier to secure, store items. I could remount the compressor so that it will be upright in the new position- but would the evaporator function properly on it's back?
Amazing Instructor. Intrigued to learn more about this field now. If he had online virtual classes or near me , I'd instantly change careers. 🙋♀️ 👏 🏆👍
Great Teacher.His students will prosper.👍👍
I agree he is a great teacher and handsome too
Excellent teacher !!! They couldn't ask for anyone better.
I didn't know McConaughey was teaching refrigeration
Right on, right on, right on.
Must be a great school. My school couldnt afford new meters smh.
Awesome Teacher. i Like, OLE!
Very great video. I have a little large small refrigerator. It worked great but I had it on a roller cart to move it, it slipped off and tipped about 2" to one side. When I discovered that ( after 2 days or so) and I plugged it in, it didn't work again. I didn't drop it or anything. Do you have idea what could have gone wrong? Thanks in advance for your help.
Dude is a great teacher. I learned so much!
No if it was locked up it would be pulling LRA or greater.You definitely have an issue but,it’s not a locked rotor.High Amps yes over heating compressor yes.I would begin my diagnostics at the capacitor.
yea... Lol i poked a hole in my mini fridge about 13 years ago ..
helpful video . thank you so much keep on
+moe's suliman thanks!
First thing you should do for any refrigeration/ac call is grab the suction line and the liquid line, every time. You’ll immediately know if that compressor is running, and based on how hot/cold the lines are you can make a determination if it’s low on refrigerant. Also touch that compressor and feel how hot it is. You can troubleshoot and rule out a lot of potential issues just by feeling the temp of different components
I am waiting for part 2 my mini fridge is doing the same thing and I want to know what I need to replace to fix it, Jesus, I just noticed this was back in 2017 and this is 2019 I don't thing it will be a part 2 at this point, so please if some one knows what need to be done just comment below.
Here is the part 2: ruclips.net/video/vEmSWvLOfMc/видео.html

hi Guys,
Foamed condensers in the inside wall of the mini cooler are very bad for service.sie rust fast and then only a capacitor builds on the back for help
🎉🎉🎉🎉🎉🎉❤❤❤❤❤❤😮😮😮😮😮😮. Awesome thanks for knowledge..... Am a. Student of. HVAC ..... now... That just learned ENGLISH.... LITTLE.. &. ALSO.... ELECTRIC 💡⚡ ELECTRICITY 🔌⚡
I laid a mini-fridge on the back for 7 hours, and it then leaked brown ooze. Ooops.
It then sat upright for several days, plugged in, is cooling, but the backside is very hot. What should I do?
Nice video!!
Man I love this. We need to get this back in every high school in America!!!
May I have a question: Does the Whirlpool 4.3 cu ft Mini Refrigerator have a fan somewhere in it? If it does, where is the fan located? Thank you for the answer.
Lot of nuances to pick up on here.
Thank you professor.
Thank you Edison HVAC.
My mini fridges little freezer section still freezes up into a solid block of ice. Have to defrost it twice a year. Right now it started ticking or clicking multiple times a day. It still runs and gets cold and stays cold. It's really loud and getting more annoying by the day. 🤣
Is this high school? If not i should definitely go ahead and get a "paper" from em lol. Class seems SUPER easy!.
Try explaining the bi metal distortion of the Klixon o/load and how it works and WHY is it always on the C ( common) ?
That’s unit 4 class lol
Im Following along with a multimeter and my garage mini fridge that quit cooling. Same situation compressor comes on a few seconds then the overload switch trips. Maybe i can save it after all with this pros lesson!
Sahm here trying to fix my mini fridge 😅
I had to go back for the right words, but I think the water drip tray melted on top of the black compressor.
My freezer was melting. There was no oil, but the compressor is warm.
It’s unplugged until I figure this out 😅
He is a great teacher! There was a ticking noise I kept hearing that caught my attention on my fridge 😮
Wait 1 is the coldest setting
Depends on manufacturer
Ok look now I got a mini refrigerator and the mice messed up the cord to it ( I got some Decon mouse poison and don't have that problem any more ) I just need to know how to replace the power cord. Well you please do a video on replacing the power cord.
