Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today. lets get started.
What you need to do is pull a refrigerator away from the wall and remove the bottom access panel that covers the compressor, there will be a fan there you need to see if this fan is running for one,if it is running make sure there is not a lot of dust buildup on the coils back there, what you get this removed and check the fan let me know we will take it from there.
I'm Marlenes husband, Jim. I pulled the fridge out of the wall enclosure and there was a metal grill/panel. To the right was a grating and behin it was a 'rolled oats container' sized screen/mesh cylinder. aAt the left end of the screen cylonder was a 4" plastic fan blade that was turning. I cleaned greasy dirt from the mesh wiri cylinder and it seems like the air flow was much better. The temperature inside went from 32 degF to about 25 degF in 15 minutes, and 20 degF in about and hour. We have it set at '9' (out of 10) on the thermostat for the freezer. The big test will be it's regenerative capacity after you open it a couple times to take things out and put things in/back. It just didn't recover. After the "recall repairs" the new computer/program which kept the compressor running after the door had been left open for too long, it worked quite well. I don't know if I cleaned it well enough to help enough ... talk to you tomorrow.
