Not able to get a freezer thermometer but ran tests shown below
Service Test 14 - Door Ice Box Thermistor
Service Test 16 - Door Ice Maker Tray Thermistor
Service Test 59 – Ice Box Fan Test
- shows “on” and fan runs
During normal operation I don’t hear the fan kick on.
Ice Box (IB) Fan
The IB Fan is a variable speed fan located in the F(freezer)C(compartment). It circulates air from the FC Evaporator area to the IB in the left RC door to maintain temperature at its set-point. For models with an ice maker in the FC, it also circulates air over the FC ice maker.
The IB fan is supplied with constant 12.7 VDC power from Orion board P16-4. The fan is switched On and Off by a 12.7 VDC gating signal from GF2 board P9-2. The gating signal is adjusted based on temperature to change the speed of the fan between HI (3450 rpm) and LOW (1725 rpm).
The IB fan is On any time the FC fan is On. The IB Fan is Off when the FC fan is Off.
Do you hear the fan in the freezer running? If so, the IB fan should be running too.
The IB Fan is located inside the freezer behind the back panel in the freezer.
Got someone to look at it. Says defrost for 48 hours. If after a week the freezer goes back to getting warm/frosting up the fan then I will have to replace the control board and defrost heater.
What are your thoughts.
And do you have pointers to replacing the defrost heater is need be.
Service Test - 89 Run FC Defrost Heater
• When entering this Service Test, defrost heater turns on and stays on for 5 minutes or until the evaporator thermistor goes above 60°F.
• “ON” will be displayed while the operation is executed.
The evaporator thermistor has to stay below 60 degrees to keep the defrost heater on. So you can put the evaporator thermistor in a cup of ice water during this test and see if the defrost heater stays on.
