Help With Side By Side

My refrigerator and freezing were working fine two days, ago. Yesterday morning, noticed the sherbet we got was soupy. The refrigerator remained fairly cold through the day. Last evening, we noticed the unit was running cool, instead of cold, so removed everything and unplugged it overnight. So, if there was frost, it’s gone now.

The fan is running, but the air blowing is only cool. The compressor clicks on and is not running hot. Have thoroughly cleaned everything on the freezer and refrigerator.

I am stuck and so hoping it’s not the compressor itself. Any ideas?

I would pry off the compressor start device from the side of the compressor.
If it rattles when shook, it’s bad, order it here 5304468029
