Hello,
Have a Whirlpool fridge that quit working all of a sudden. Tried replacing the start relay and that did not work. Checking voltage to start relay RED and White I only have .5 VAC. Looking at the wiring diagram today I see that the condencer fan runs off the same voltage supply and fan is working??? Diagram shows an overload before compressor. Is that separate from the relay?
Side note: I can here the relay click on an off every few minutes and the relay seems hot. Compressor windings 5-8 ohms.
Take a look at items 13 and 16 in section 11.
Looks like item 13 includes the overload.
If you click on the items description or picture a new page will open with more info (Q&A) about that part.

Something is weird here.
Red to White should also be the fan voltage and it would not run with 0.5 volts across it.

See the parts.

Below is how to check the windings.
Note that bad winding readings can tell you if the compressor is bad.
But good winding readings do not tell you that the compressor is good as it may have other internal problems.http://www.acmehowto.com/howto/appliance/refrigerator/refrigerator.php
Rechecked volte to compressor and it is good. (123 VAC). Needs compressor.
One question I do have though, is under the section for checking a compressor it stated that checking the resistance of the pins on compressor that it should show zero ohms. shouldn’t you see the resistance values of the windings?

Yes you should.
Looks like they are using too high of a meter scale.
Using a 200 ohms scale on a meter you should see.
1 to 5 ohms for the run winding.
3 to 11 for the start winding
Then the addition of the above two readings when you read the windings in series.
Also infinity ohms from all pins to ground.
Be sure to short the meter leads together before starting so you can see if there is a zero offset in the meter.
