Ge 48” not defrosting
GE psb48lsrabv
new defrost timer
new defrost heater
new Ge control board.
After 9 days the evap coil inside the freezer freezes and becomes solid.
OHM tested the heater, pan heater, and defrost timer. All ohms our OK
when I put the freezer defrost timer on manual on the control board defrosts and the heater starts right up.
however, it never seems to go into defrost on its own.
When i I run the thermistor check 1-10 everything comes back as passed.
I have checked the manuals and ran my tests according to the manual and everything comes back.
Anyone know these fridges well? Should I just manually check the ohms in the thermistors even if the control board says they pass? I read once that someone replaces the ones in the fresh food compartment and it made their freezer heater go into defrost? This is driving me insane! Help!

If anyone cares, after poking and probing everything and it all ohming and checking out. I decided to see if the fridge self diagnoses was correct. I purchased a new Evap Thermister and tested the old when when removed. Althought the OHM was correct for the temperature 4.3KOHMS at 80 degrees. The actual evap temp was -24 degrees. the Control board thought the Evap coil was always 80 degrees, so it never called for freezer defrost. So life lesson, don't trust fridges self diagnoses.

My apologies. I had replied to this soon after you posted it. I don't see my reply. 
In that reply was a request for a model number.
Glad to see you have the problem ironed out.
