Noticed the hot area between doors indicating too much heat. I cleaned the condenser coils under fridge well but his did not solve. Opened back of fridge to find overly heated compressor. Noticed fan not working. I set up plug-in fan and retired for the evening. In the morning, condenser fan was on! Took away the plug-in fan. After while, condenser fan not working and compressor again became overly heated. I replaced condenser fan. It initially came on, then off, and it stayed off. Set up the plug-in fan again. Went to bed. New condenser fan was working this morning! Seems signal telling fan to come on with the compressor is somehow intermittan as the fan motors do run but won't restart with compressor. What might be causing? control board? Condenser control unit (inverter box)?? Help!

Thanks. I am leaning that way but first I was going to try and visually inspect one more potential cause to see if there is something that is showing signs of burn or being blown. This particular fridge looks to have a part called "invertor box" which is described elsewhere as a condenser control unit (AP4308835) and a circuit board in the control parts diagram which is housed inside the interior control panel (AP3773712). Which of these two items would be responsible for condenser fan motor control? My only thought is that if the fan does function and it does so intermittently, perhaps the part responsible for sending the message to the fan may be the culprit. If I can isolate the part I can at least look at it to see if there is something obvious. If all looks like it should, I will get the experts out. Is my logic flawed? I may be completely off base on not even know it. Thanks for any help/assist you are providing. much appreciated.
