Hotpoint/GE HTS20GBNBWW Fridge

Not cooling enough, I can hear the freezer fan and lower fan running. The lower coils were dirty and I cleaned them with brush but need to really take the water hose after them. It is in my garage and I am in Texas. Freezer temp is 22 and fridge is 55. Any suggestions? Thanks Michael

  If its all running you could have a. Defrost isssue causeing buildup of ice behind the pannel in freezer of low on charge.

  Unplug remove back pannel and. Look for ice and take note of the patter on frost on the coil.

 Is the motor in bottom rear vibrateing/running?

Compressor is running, I will check the freezer coil for ice. Thanks Michael

I haven't looked at the coil yet but I thought I would leave the temp probes in overnight and see what it should when the garage cooled down. This morning the freezer was a 2 and the fridge was at 50. Could I have a door problem from the fan in the freezer not getting enough air to the fridge? Thanks Michael

The way it looks I would suspect the defrost thermostat, which shows to be no longer available.

Well this has been running good, The only defrost thermostat I could find was used but now its freezing up. I would suspect the part has failed again. Could wiring in a adjustable defrost timer and trying to find the sweet spot work to keep it going? Thanks Michael
