I have been repairing refrigerators for many years but this one has me confused.

The initial problem is that the unit would not go thru a defrost, so eventually a warming freezer and fridge after about 3 days.  Manually defrosting with a hair dryer brings everything back to normal.

The manual defrost sequence (cycle fridge light switch 5 times within 6 seconds) does not work.

After checking the defrost thermostat and heater (both checked out fine).  I realized that the fridge would reset itself, like someone unplugged it and plugged it back in.  The freezer and fridge temperature settings that I set on the temp control board would revert back to default settings and the fridge would beep.  This seems to happen about every 2 hours when the fridge is plugged in.

This resetting of the temp controls so frequently, makes me think that the defrost issue is just a symptom of a bigger problem.  Before I replace the temp control board, I was wondering if anyone has seen this before and if there is a way to prove that the control board is bad. 

FYI - The Control board in there now is #241739710 whis is supposed to be the approved replacement for the original part # 241739702.
