kenmore side by side fan working, compressor hot, when compressor tested with unit off checked for open windings by ohms found resistence leg to leg, do we need a new compressor?
maybe just a relay
Its a Kenmore, the overload and relay combination have a history of going out. I bet that is it. Tom ApplianceEducator.com

You now me, the Appliance Guru. Tommy boy
[quote=kayakcrzy;39951]You now me, the Appliance Guru. Tommy boy[/quote] Yup. Sheilas forum is loaded with garbage ads.:eek: What 's up with that. 
You have 3 pin (triangle) you have to check with a Ohm meter how to check:
Common : Is the biggest resistance
Start: Medium
Run: Smallest
If you see that all of them are almost the same it means shorted or if you touch one of those pins with a pipe & you have a continuity it means its shorted 2.
Hope it was Helpful!

The total resistance between Run and Start should equal the sum of Start to Common and Run to Common.
Example: C to S = 5 Ohms, C to R = 2 Ohms, Then C to S = 7 Ohms
Testing for Grounds: Using an Ohmmeter place one probe on a good ground
such as the ground screw on the compressor. The other probe should then be placed on one of the pins as so stated. If you get a reading, the compressor is grounded.
Testing for open windings: Using an Ohmmeter take the leads and test between any two pins. Reading infinity compressor has open windings.
Testing for shorts: Using an Ohmmeter, place the leads between any two pins. Reading zero shorted compressor.
So much for “Compressors 101”
nicely done Icehouse lol
Thanks. I love what I have been doing for forty years now. God I’m getting old. :eek:
I was trained by your generation. lol I’ve only been doing it for twenty.
Icehouse, isn’t that a bunch of garbage on sheila’s site. It hard to wade through it. Ice house wouldn,t you consider a tech with 20 years experience a rookie. LOL!!! Tom ApplianceEducator.com
Thats why I’m here so I can learn more.lol If I’m ever wrong please correct me I’ve been wrong once or twice before 
Like I said I was trained by the best.
I am only as good as you guys, just been at it since the days of the Westinghouse Ratcheting Defrost Timer to count how many times the door open and closed (sound familiar). And GE Compressors had a Fourth terminal.
What i meant it’s to find the Common, Start or Run.
If Between 2 pins of the compressor (since it’s a triangle) you have the biggest resistance. It means that the other pin is the Common.
If Between the other 2 pins ít’s medium resistance. It means Run
The final pin is the start!
Maybe didnt explained well
I like it here a lot good support!!! Hope to speak to you soon!
Compressor terminal identification U.S. Army Refrigeration School Fort Belivor, Virginia.
Compressors have three terminals that may or may not form a triangle, sometimes they are side by side, sometimes one on top of another However you read them like a book. From left to right. Common,Start and Run. This applies to most American Compressors.
The other method is the A,B,C method.
- Any two pins and call them A and B the other pin label C
- Take a reading from A to B and write it down. = 5 Ohms
- Take a reading from A to C and write it down. = 2 Ohms
- Take a reading from B to C and write it down. = 7 Ohms
- Add all A readings. 5+2=7
- Add all B readings. 5+7=12
- Add all C readings. 7+2=9
- The largest reading is B, so that is Start
- The next largest is C, therefore is is the Run
- So that leaves A, which is the lowest, it is Common
Thank you everyone for your support and I hope I am not annoying.
A B C D E F G. Mr. Ice house come and help me. LOL. Tom ApplianceEducator.com
Tom, I help everyone I can. And twenty years ! I get guys with 7 months of “Apex Technical School” who think they know everything. :eek:
As a test I take them to a site with a Trane Centra-Vac centrifugal chiller and ask them to explain it.
That’s way to give them a reality check. LOL Tom
I love when they say "so what does this thing have to do with “Air Conditioning”.
