After unplugging and defrosting my ge tfx20nw it
The defrost system has failed. It is made up of a timer, defrost thermostat, and defrost heaters.
The timer is located behind the light guard in the fridge compartment.
The heaters and defrost thermostat are located in the freezer compartment, behind the back wall.
1. With the machine running, in the fridge compartment, pull off the thermostat knob, and then unclip the light guard.
The timer is behind the panel exposed, but has a hole to insert a small screw driver to advance the timer.
Turn the timer clockwise until the machine shuts off. Wait 45 plus minutes. If the machine turns itself back on the timer is good.
If not, remove the panel, and install a new timer.
2. If the timer is O.K. then the problems are in the panel on the rear of the freezer compartment.
Unplug the machine, and remove the rear panel. Allow it to defrost.
There are two quartz radiant heaters, one located on the bottom of the evaporator coil, and one half way up. There is also a defrost thermostat clipped to the top of the evaporator. It is a round disk about an inch in diameter.
Purchase and replace all 3. You may need wire nuts to splice wires together so purchase them as well, when getting the other parts.
Go slow, the heaters are easily damaged or broken if handled roughly.
