My refrigerator is not cooling. It appears that the compressor is not running. When starting (relay clicks), it draws 10.6 A (ammeter clamped on power lead). The LRA is 21.6 A, so I am confused to why the compressor does not run. The relay clicks on................clicks off every minute or so.
The evaporator and condenser fans are both running (both replaced last year). The condenser coils were also cleaned last year.
Thank you for your assistance.

Hi,

Unplug your refrigerator from the wall outlet, then remove the compressor start relay.

Once you have the compressor start relay off, shake it and see if it rattles.

Here's the compressor start relay for your model:
WP10097202 Relay, Start


If NO rattle, What I do is ohm test the 2 parallel holes on it. Take the wires off of it(TAKE A PHOTO OF IT FIRST, SO YOU WILL KNOW WHERE THE WIRES GO WHEN YOU REPLACE IT) and ohm the 2 parallel holes on it.

Normal would be under 12 ohms, when reading on the multimeter.

Hello Jake,
Thank you for your reply.
I was away from home for a few days and I am just getting back to this.
I ohmed out the relay. It measures about 6 ohms. It also did not rattle.
I also ohmed out the compressor. There is continuity across all three pins (all combinations). It is also not shorted to ground.
I bought a couple of "3 in 1"s. They are different HP ratings; I did not know the rating of the compressor. It appears the compressor still is not running (remains cool to the touch and is quiet) when they are used in place of the relays.
Thanks again for your assistance.

Your compressor start relay is good.

If the compressor is still not coming on, and the compressor start relay still clicks, then your compressor is shot.

Hello Jake,

That's not really what I wanted to hear, but it's what I expected. Thanks for confirming that.

It doesn't make sense to replace a compressor on a 20+ year old refrigerator for ~$350. Time to call the scrap metal guy.

Thanks again for your help.

Yes, I agree.

Glad to help!
