I don't remember when I, or anyone, cleaned the coils, so I vacuumed them, blew out dust as well, just a few minutes ago. There really was very little accumulation, just a light coating on some of the coils.
So, now I will wait and see what happens to the temperature. I'll check back with you later after observing the thermometers. Will I be able to reply directly to you? I'm going to log off for now.
I decided to keep an eye on it. The compressor and frame around that area were getting very hot, too hot to touch. I see the fan is not running even when the compressor is running. So, for the time being, I set up a floor fan to keep fresh air passing thru, and everything has cooled off except the compressor. Looks like there is a fan issue. I don't have any meter to check for power to the fan. If it has to be replaced, what is the procedure?
If the fan is not working you need to find out if there is voltage going to it. With the compressor that hot you could end up causing damage to it if it stays hot.
Keep the fan going on it and see if the compressor cools down enough so that you can touch it without burning yourself. If the fan will keep it cool go ahead and keep using it. If it stays hot it would be best to turn it off until you can get a volt meter and check for voltage to the fan.
If there is voltage replace the fan. If there isnt replace the control board.
Thank you very much. I had to call a local service man, since I don't have a meter or the tools necessary to remove and replace the fan. End result, the motor was OK; the control panel had to be replaced, and the service man had both in his truck. fridge working much quieter now, temp remaining fairly constant!
Just thought you would like to know you had the right diagnosis.
