1 month ago my refrig was no cooling. so I defrosted all the frost on the coil in the behind the panel (inside freezer) and replaced defrost heater and thermostat. It was ok for about a month. but it happened again. and I defrosted again but 4days after it happened again.
do I need to replace defrost timer? where is it?
someone said it is incorporated in the mother board in the back.
another said it is in the control board in the fresh food section inside the refrig. who is right? what should I do?
and do I have to replace heater and thermostat again when I replace the timer?

Please help me......

Neither is right, there is no defrost timer, and the board is located at the back of the cabinet, you need to pull the refer out to get access to the access panel where the board is located. Please provide serial# also, can you give me the GE part# you used to replace the heater, and I will help you with your problem, I am a GE tech for 8 years now

What is the frost pattern on the evap coils, is the whole thing iced up top to bottom, or is the top half of the evap iced?

[jl0055]

whole thing iced up top to bottom

Take the wires off the heater and do a continuity check of the heater

[jl0055]

what do you mean? disconnect the wires from the heater and see if heater works?

[abadfish66]

Do you have a volt meter? If so take the wires off the heater and take an ohm reading of the heater to see if it is good or not

[jl0055]

No, just voltage tester (to test if a outlet works). not volt meter.

if I replace heater and thermostat again
and the board at the back too, then will it be OK?
