Refrigerator/Freezer abruptly stopped cooling. After a cursory investigation online and switching thermostat off and then back on to max, fan came on, but no cooling.
Just about a year ago, I used Appliance Parts Pros very successfully to replace both water solenoids. So I'm back at the well trying to buy parts to fix this cooling issue.

Thankx, Richappy, for your prompt reply! I really appreciate it. The empty fridge is in the kitchen and, because of ongoing painting there, I can't pull it out from the wall for a couple of days. However, I did recycle the defrost timer before bed last night, and this morning it's running BUT not cooling. Yesterday and again today, when I felt the back wall of the freezer, it was and is still warm to the touch, so no icing up. I have right this minute turned the temperature control completely off and back on the max. Fan stops and starts running but no unusual sounds, e.g., clicking, from the compressor. The fridge just continues not to cool. Reg Doherty, Suburban Philly at Paoli. P.S. Noticing your location, I'm wearing my Penn State Wrestling T right now. Have a super day.

Just got to fridge. Compressor is warm to the touch on top but not vibrating. It feels like it's running but not doing anything.

Thankx for your good help. I'll have to take off the part to shake it. I assume if I shake it and it's burnt I can smell it, right? Would there be anything else besides this part. After all, the fridge is about 11 years old. The Start Device is @ $45 total and, if there's something else to order, I'd prefer to order it at the same time to get all done at once. Have a super day! Reg

Sorry for the delay. Our home is in complete disarray with painters everywhere and in the kitchen, where the fridge is located.
There was a "small, black plastic ptc ??? device on the side of the compressor". This was held in place by a wire bail. I removed this one-piece part, which, according to the parts catalog should be three separate parts. However, this was just one part, containing all three and solidly welded together.
I shook the part, asked my wife what she heard, and she described it as sounding like "salt in a cellar". So, I decided to break it open and did, in fact, find burning and small pieces." The wiring harness going to the unit has but two wires, both, if I remember correctly, the same beige/tan color. So polarity isn't an issue.
The total price of the three pieces, Cover, Overload, and Start Device, at APP is close to $100, without shipping. So, doing a little research on ********, I found what appears to picture the EXACT same thing as I had removed, i.e., a "Genuine Whirlpool Refrigerator Relay Overload Start Capacitor 67005560 W10613606" for $43.90. As this is some $60 difference, I ordered it last night and it has already been shipped. There's a 14-day return policy, if necessary.
Being a real technophobe, I am at a loss how to send you a picture of the wires. Of course, I have a smarter-than-me-phone [sic] with camera but how-tos elude me to send a pic to you. Sorry about that!
I really appreciate your patience and promptness. Judging by the number of your posts, you're a real pro. I'm at the far end of that spectrum!
We going to get the fridge moved to the basement today, where, when I get it fixed, we can use as a back-up. This pleases my Italian wife... more fridge to fill up! Tomorrow I'll have more room to maneuver.
Have a super day. Reg
