Question about GE Profile Energy Star PSC25MGS Side by Side Refrigerator
Periodically the freezer seems to go into a defrost mode and melts all the ice in the ice bucket. Later it will refreeze. If I do not keep a bucket under the ice bucket I end up with ice cicles hanging down through the freezer. I have been told this is the fan. But why does it seem to correct itself later. Problem occurs about every 2-3 days.
GE Profile Model: PSC25MGTA
As far as I know the fan does not normally cause this kind of defrost, but some of this fridges use a complicate temperature control system and you never know.
If the problem is restricted to the icemaker, the only way the ice can melt is if the heating release system starts heating up because of a contact. The problem is that this icemaker does not have evap system inside icemaker. Contrarily to majority of built in icemakers, this model uses an auger based mechanical release system. If problem is restricted to icemaker, then I would replace the whole icemaker assembly: ICEMAKER ASM (MECH ICEMAKER ASM).
If the whole unit is defrosting, then the first part to test is instead the defrost thermostat DEFROST THERMOSTAT (THERMOSTAT DEF). Defrost thermostat can be tested using a multimeter. To test, cut thermostat contacts and read impedance with tester set at Rx1 to read impedance. The thermostat must return low or 0 impedance at low temp, and infinity when limit temperature is reached. Also check for any weird thing in the defrost system, also temp sensors should be tested.
This fridge has also an humidity control, when dampness is eccessive, the control board will start fans. That can also be causing the problem.
A technician on site will probably test the defrost system, and then replace the control board (MAINBOARD KIT D/EVAP (KIT MAIN BOARD SERVICE)
Try first disconnecting fridge from power and allowing a complete defrost overnight. This can fix a jammed sensor, and will reset the electronic control board.
If that does not work, check the warrant status, repairing this fridge it is quite easy to replace wrong part, since the fridge is working, a slightly defective elecronic control will be impossible to test. And repairing under warranty will cover any part needed. If warranty is expired, call manufacturer and discuss purchase of a five years warranty extension.
To proceed with the repair, test the defrost system, check wiring and temp sensors, then replace the control board, that is most likely the problem.
