I pulled the fridge away from the wall and cleaned the back coils a few months ago.....they definitely needed it.
Everything seemed fine for awhile...
Then the freezer seemed to have issues staying @ 0 degrees then shortly after the fridge couldn't retain its temps.
Fridge stays around 50-60 degrees when its set on 40-46
Freezer is set on 0 degrees and everything is just barely frozen like a thawing snow.
It seems to work for awhile after i unplug it and then a few days later it stops cooling again.
I have everything out of it now with the temp sensors and thermostats pulled on top and bottom.
Put a multimeter and tested continuity on the the thermostat and Ohm tested the temp sensors @ room temps and in ice water.
They all seem to be fine.
Checked the thermal fuse on the fridge...it doesn't appear to be blown.
Couldn't find one on the freezer side.
Not sure where to go next.
EDIT: I have power consumption history on the fridge....the compressor is working i see it running @ 200w periodically through the day.
