Went out today on this refrigerator. Complaint was poor performance in freezer.
Lots of condensation on the augur motor box and the IM direction solenoid is frozen in place. Customer complained of bad freezing performance; everything was frozen when I arrived. Temperature was set to "8" with "9" the coldest possible setting.
Baffles opened and closed but took a long time to respond to controls and had a grinding sound when doing so.
Went back to the control board and took thermistor readings. Evap thermister made sense, showing about -10F. Freezer thermister was way off the mark, was showing freezer at about 23F, when actual temp was 16. FF compartment showed a correct temperature of about 41F. When I plugged the unit in and restored function, I had to push the FF setting to "8" before the baffles finally opened and I had my grinding sound again.
My question: I am going to replace the baffles and the freezer thermister. Should I also replace the board, given that it should have been opening the baffle based on the temp sensor reading? Or GEs just take a longer time to respond to temperature sensors than other units?
