Do you have any promo codes?
10:21 when you test the resistance, doyou test a specific probes or all 3 should work ? For me Only one is showing resistance/continuity, the 2 others aren't
Thankyou shwring gues good welcome gues
Thankyou gues all shering
Brother I am BLOWN AWAY by the knowledge you shared in this video !!! I am retired HVACR tech and no way could I have explained everything the way you do here. Awesome job !
great teacher! clear and detailed photos and explanations. I am an old DYI guy playing and learning how to fix the AC on our camper van. I learned from this video the importance of changing all capacitors and relays at once. I worked my way one by one and have ended up with a problem again, probably a new capacitor blown.
Thank you so much for this fine and informative video! My fridge has one of the modules with the built in control board, and it failed last. Thanks to you, I was able to isolate the probable issue and swap out the part myself. Up and running, saved a lot of $$ and maintained social distancing.The new trifecta!
I own a food establishment and do my own refrigeration maintenance. Note that I am properly equipped and EPA certified to do so. This is an excellent video!
Thanks a lot Jean!
God Bless RUclipsrs like you who share knowledge helping the average fellow diagnose problems like these. Very clear, very kind of you.
thank you for the very informative video sir, I myself am a hvac and appliance tech of 20+ years and you might have schooled me on a thing or two in this video.
always wondered why overloads failed now I know. I can honestly say I have never taken the time to take one apart and look at it.
I have a 17 year old mini fridge that recently stopped cooling. Upon plugging it in, the compressor would hum for a few seconds and then the overload would click and trip open. Checked the protector, very low ohms. Checked the start relay, completely open. No rattles, but when I took off the cover the disc and contacts looked pretty bad. Wanting to make sure a new start relay was the right fix, I made a jumper for the start relay pins, and then plugged in the fridge just for 1-2 seconds and unplugged it, and the compressor started up and sounded normal. After watching your video and the troubleshooting I feel confident enough to order a new start relay. Thank you for sharing.
Today I changed burnt PTC Thermistor in my Samsung fridge. Your instructions mentioned to check the resistance between starter and running inputs (bottom two out of total three)of PTC. It should not be open. Guess what! Mine was open. Along with other tests I decided to chagned PTC for $15.00 from Grainger. It worked. Thank you very much for a very good explanation.
Also as always thanks so much for the detailed information. I can always tell you take pride in what you do. I hope when my apprenticeships are over I can afford to repay you for you're help.
Thank you very much and hey just tell others about the channel and the book, pass the word, thanks a lot Daniel!
@@acservicetechchannel definitely will. It's the least I can do.
Fantastic tutorial - with just my basic air conditioning training and your explanation of the components I was able to diagnose my 1970's Coldspot refrigerator - thanks for showing some of those vintage components, it really helped my comfort level!
There's "PTec" units in the hotel I work at (old I know 😂), this was super helpful! Thanks man
Clixon in the refrigerator .. Thank you, God bless you, my dear
Recently had a Frigidaire mini-fridge that wasn't cooling. Compressor was hot and when the thermal overload reset, it was pilling 9 amps with an LRA of 11. I checked the PTC and it was reading about 50 ohms. I disassembled it and found signs of carbon/overheating on the run terminal/PTC contact surfaces. I scraped both surfaces down and got a reading of 9 ohms. I reinstalled it and the fridge started up with 1.3 amps while running. It continued working while I awaited arrival of the $10 replacement. It's running fine. Thanks for the great video which I found after I had repaired the fridge.
That was a great demonstration of the different relays and caps for a domestic refer can. Thank you for the video. And most of all HVAC ON AMERICA!!!
Thanks a lot Ray Ray!
Wow, tons of information. I did see my relay and capacitor set up. I have a craftsman digital meter that I use for small engine wiring. Not to sure about setting up for ohms on mine to accommodate to test these pieces. I've been out of a refrigerator since Wednesday
This is by far the most valuable video on relay fault finding on the web. Your instructions are the best and most easy to understand. Well done and thank you for sharing with all of us.
Excellent explanation- really appreciate your sharing. Keep up the great work!
I can’t thank you enough, I’ve watched and currently watch a few hvac channels, you are my favourite
Awesome demonstration, thank you.
Thank you for your support!
Thanks for your help and advice on how to do trouble shooting
Really helpful! Thanks for sharing 👍
Excellent video - just what I was looking for thanks for sharing.
Awesome, thanks Mark!
Thank you so much, that was very helpful and well explained
Glad it was helpful!
A truly magnificent, very helpful video, and information. Thx
Glad it was helpful!
Great tutorial! Very clear explanations. Super helpfull my friend! 👍👍👍
Lol. You said tale a picture. Cool. When I started doing this in 1978 we had to make a drawing. I watch your videos review and try and get my wana be techs watch them.
My first year teaching, I told the student to take a sharpie and write the terminal letters on the unit before disconnecting or draw a picture on a piece of paper. He looked at me with an odd look on his face as he slowly pulled out his phone to take a picture, ha ha!
This helped me fix a midea freezer that was DOA. All the parts tested out fine but i noticed the connection to the relay was very loose so I tightened up the connector and the compressor started humming along!
great video this help me repair my freezer
Excellent video partner thank you for sharing!!!!!!!
Thanks Jimbola77!
Found overload protection was open on my mini fridge insignia 2.6 cf ... In Dallas lots of lighting occurred maybe jolted it.. Worth trying it for 5 bugs .. Ordered it will see.. Many thanks for your video
Thanks for sharing great information my just stop working freezer and refrigerator.
Great job and video Craig
Thanks Kenny!
This is very helpful, great video.. thank you
Thank you. All the way from South Africa
I noted that there was no thankyou sent for you from Craig. Maybe because you are from South Africa (like myself) and they probably think we are still swinging in trees here like Trump ha implied. Lol
Very helpful, thanks for posting.
Glad it was helpful!
Thank you sir. I learned a lot.
Glad to help!
Excellent & good teaching...👍🏽 ⭐️⭐️⭐️⭐️⭐️
Glad you liked it!
Very nice video, thank you.
Thanks DC!
Very nice video good information thanks but I have a compressor star some time and it gives hard start some time
thank you..for telling me how to check the refrigerator components.
I had to subscribe bro. You are good, please keep doing what you do. Following you here in Kenya.
Thanks for the sub
Awesome video! Thank you.
Tetorial overload dan kompresor yg sangat keren ....mantap
This was very informative keep up sir and share with us it wil help in the future👍👍👍👍
So nice of you
Great video to save for future. Thanks for taking the time to make it and share. Do you know if there is a good cross-reference source for components in case they no longer make the exact model component. Also, any comments about using the universal 3in1 components you can get online?
You the best teacher ❤️
Thanks so much JD!
Another great video!
Thanks Familia Sanchez HVAC. You have been around commenting since the start! Thanks!
Excellent video, congratulations
Thank you!
Great video, Thank you! Is not UF is Miu F, is a Greek M, used to indicate MIcrofarads.
Thank you for this miniclass!
is it possible to measure resistance reading between the start and run winding of the overload protector & PTC relay combination kit?
Very nice video. Thanks
Thanks Lance!
My Kenmore Elite (Whirlpool) refrigerator stopped working when it was about 5 year old. I took the start relay off and shook it and it rattled like a maracca! Got a new one from the parts store and it hasn't failed since (15 years). Had other issues with the fan and ice maker and water in the door though.
@9:00 those capacitors I’m fairly certain were run capacitors. Their mfd ratings are low. Even supco has kits that identify these as run capacitors not start caps. Still a great video!
Yes absolutely are run caps on the TSD's thanks and good catch!
I think I'll grab the paper back. Great video.
Great information and clear
Glad it was helpful!
Thank you sir. I'll be buying products off your amazon shop.
Thanks a lot Earth is hEart, I really appreciate it!
Good
Thank you very much, my GE got a relay starter bad. 25$ @ at Amazon, i will replace it.
Hey Craig I’m thinking abt buying your book! Are you planning to write another book for more advanced techs? Where we learn more about theses relays and and Hvac wiring ect and more complicated Hvac situations that we might encountered, but regarles i think 💭 I need to have your book handy with me everywhere that I go until I feel confident enough. Thank you for sharing your personal experiences you make us better!
I would like to put together a book on electrical and furnaces. However it all takes a lot of time to get it all exactly how I want it, thanks and please let me know what you think of the existing book after reading it. Thanks!
Great stuff as usual. Can you do a video on replacing these with a supco 3 in 1?
I'm hoping someday you'll put all these videos on CD or flash. I would buy it just to watch it at hotel or away from home. I saw your "video-book" but it linked to youtube which is useless in hotel because of the slow internet. BTW, study guide and quick cards I ordered from your web site are really kool. Thank you.
Great video...!!
Great video and great details!!!! But what to do if one of the three leads coming off the compressor or lose? Can it can fixed or does the compressor needs to be replaced? The other two or fine but that lead is lose with a hole around it.
Love the explanation
Glad it was helpful!
شكرا لك
سعيد للمساعدة! Glad to help!
You are the best of the best.
Wow Beautiful info thank you so much
Great video, you are the real deal
I appreciate that!
Excellent training.7/11/2021
Glad you think so!
Thanks.
It's a nice video and I have learnt a lot.
To save all the time of testing individual parts I find it much easier and cost effective to just remove old parts and install a 3 n 1.
Cool video. I ask are all these fridge or freezer compressors for commercial refrigeration?
Good sir. Thank you.
So nice of you
Great helpful video, my question is if I check everything work but the compressor overload keep tripping please advice.
Seems 88/108 is fairly common with vintage refrigerators and freezers. I'm troubleshooting a 42+ year old Sears 106.6327150 upright freezer that went out for the first time last summer, and it has the same spec for the capacitor in it. I have yet to remove it from the plastic housing it's mounted in to see if it's leaked at all, but one afternoon this coming week I'll be going through it part by part in hopes that what made it go out was a still-available component. Lost 100+ lbs of salmon and beef when it went out last summer. Hooooo that stung the nostrils....
Good video!
Thanks a lot!
Tank you
Glad to help!
Hey Craig great viid!!!!! But... Reminds me of a request I've had rattling around in my coconut... COMMON VS.NUETRAL VS.T-STAT VS.TRANS VS.120 BLOW VS.240 BLOW VS. BOARD N.BOARD C........ANYWAY "common" is thrown around a lot everywhere and I think you are the guy that could differentiate concisely the term C.
Ha ha yeah it can be confusing but common is essentially the path back but can mean different things depending on 24v, 120v, and 240, thanks for letting me know!
AC Service Tech LLC that’s the most basic and accurate definition I’ve heard anyone explain. The world needs more teachers like you
Thankyou brother that's the best explanation 👍👍❤
You're most welcome
Straight to the point very informative. Looking for a compressor relay NSN 5945-00-110-0209 one piece. Any ideas?
thanks
Glad to help!
Galco TV refers to "OL" as "open lead". Oh is a letter zero is a number. Greg thanks for your excellent videos, well presented and accurate.
Open line, Over Limit, the list goes on but basically the resistance value is too high to read with the meter. It is reading the resistance across the air from probe to probe, thanks
@@acservicetechchannel Correct, the term is a matter of preference by the instructor. Open line or open lead is what I feel most comfortable using, again it is a matter of choice. Thanks for your reply.
Open loop
Question, My compressor cane with two types, the pin config is the same as the third compressor in your first illustration, but has the pc thermistor and overload protector attached, but also came with the third version with the start capacitor, on the side of the compressor says no start without starting device, I love you book and videos, always wanted to learn about this, Ty, Anthony
What a awesome video.
Thank you
Welcome!
Nice Tutorial , thx lot dear
Glad you liked it
The capacitor in the third one from left is start capacitor or run capacitor? Thank you
Nice teaching
Glad you enjoyed it!
What about a solid state device in place of the thermistor? I was checking a refrigerator for my home and found a tiny circuit board in the start up plastic shell that plugged into the compressor.
Hi pal, that is a very good work!!!!!
Thanks for the visit
Craig this is great video explaining these start components. I greatly appreciate all of your videos. I have a question. I work at a facility doing the HVAC throughout the buildings. Just installed a new thermostat on an old Traulsen reach in fridge. It's over 30 years old. runs great now. After watching this video and another about currect relays I am considering getting new start components for this Traulsen. Would that be the proactive right thing to do? The parts for the Tecumseh compressor can be gotten locally for under $50. Your thoughts?
❤ from Burundi 🇧🇮
Your video helped me diagnose a friends mini freezer with a broken PTC starter. I can't find an exact replacement anywhere on the web. Can I pull the PTC off another broken freezer even if the resistance is slightly different? My friends broken one is rated at 4.7Ohms and my working one is rated at 6.8Ohms. Is it safe to switch? Thanks.
first the current go in the windings of the relais to the startwinding , the relais comes in en turn the contact of of the start winding . the back emf from the start winding holds the relais ON (relais on is contact of the start winding )for the run winding . sorry my English is not good
Thanks for the vid
Any time!
Thanks that's amazing great video channel I like this post Nice I dea I respect
Have you done any videos on inverter controlled compressor?
Not on the diagnosis but resistance values will be equal on all three pairs when the wires are disconnected to the compressor, thanks!
Hi, I wanted to make this silent compressor so I got from my friend the ac compressor (from external unit) and I was wandering whether you would be able to help me with connection of my ac compressor ( ac was single phase) but there wasn't separate capacitor as I can see on some RUclips videos, there was whole like main board from computer and there were few capacitors, any way on the compressor itself is a label which says 148VDC, at 120Hz, and I have no idea how to connect it to a power supply
Great job and video. Now i am not sure what to do. Working on a wine cooler. The reading are E1 E1 DUAL COOLER. Fuse is good. Start relay ohms is .1 overload relay is 4.7? what do you think?
