I had this problem where frost would show up on the back of my freezer. The ice maker would quit making ice and the fridge side would get too warm. I have replaced the following parts at the advice of folks in this forum and was wondering if there is anything else that needs to be done.

Heater
PTCR relay
Run capacitor
Overload [COLOR="Blue"]These three parts are not related to the defrost cycle, which was your problem.[/COLOR]

The unit has been running for about 12 or 14 hours and to my knowledge it hasn't shut itself off yet. I can put the thermostat on zero and it will turn off but otherwise its just running and running. Do I need to replace this part? http://www.appliancepartspros.c...&diagram_id=22294226 [COLOR="Blue"]That is the defrost thermostat which prevents the freezer from getting too warm during the defrost cycle. You can test it with an ohm meter by connecting each lead to the two wires. It should show continuity when cold and not when warm.[/COLOR]


Also, after I installed the heater, and plugged the unit back up, I noticed that ice forms on the coils almost immediately. After it gets about half way up the ice defrosts but I never see the heater heat up or anything.[COLOR="Blue"]Your motherboard(part 801 on diagram 8 Replacement parts for GE GSS22SGPCSS | AppliancePartsPros.com) controls your timing for the defrost cycle.If the heater and defrost thermostat checked out ok that will be the problem.[/COLOR] Is that normal?[COLOR="Blue"]It is normal for the coils to be lightly frosted but it should be frosted over the entire coils. Partial frosting is a sign of low freon. [/COLOR]
Any suggestions would be greatly appreciated.
