All fans running not cooling bad board or adc how do I check i unplugged temp control trying to get compressor to cut on no voltage at compressor still.
You will want to check for frost on the rear wall of the freezer compartment. If there is frost then You can check the defrost limiter to see if it has continuity. If it does not have continuity then you would not need to change it out. You will also want to check the defrost thermistor for resistance. The resistance values should be as follows, 42.5K at 0 degrees, 14.4k at 37 degrees and 5K ohms at 77 degrees. If not within range then it would need to be replaced. If it checks good then also check the defrost heater for continuity. If no continuity then replace and if good with continuity and all other components check ok then you would need a new main control board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
As for the compressor not running test for 120 vac to the wires leading to the compressor. If there is no power then the issue will be the control board and if there is power the start relay has failed.
Ge model gss25xgnabb all fans running. Is this a bad board or thermistor or adc?
Answer Hello Rookie. If the unit is running, then all the fans are suppose to be running on the unit. This is normal.
Have a side by side refrigerator. The refrigerator is registering anywhere from 26 to 32 degrees instead of the recommended 37. Freezer is doing ok. Is this a mother board issue or something else? In October the whole unit quit cooling and had a repairman replace mother board with a refurbished one. Now 4 months later this problem. Help! Thanks
Answer Hello Mik,
You will need to check the defrost heater since it is the most common failure on this design. If it tests good with no frost build-up on the evaporator coils and the evaporator fan motor is running up to speed, you will need to check the damper for a frost build-up preventing air flow to the fresh food compartment. Don't forget to check the air return to the freezer compartment at the bottom of the fresh food compartment. Remember if frost is located in the damper area, the usual cause is a air leak at the ice dispense door or around one of the door seals.
