For what it's worth.........for all you guys that have had a problem with the evaporator fan motor not coming on for a GE GTS22.....This is what I found out.......the R-95 (2 ohm 1 watt) resistor on the board was burnt......also the terminal for one of the relays was also burnt........what I did was replaced the resistor with a 2 ohm 5 watt ceramic resistor and re-soldered the terminal for the relay and it worked....... been going on 1 month now with no problems............cheap fix but it saved me $100.............it won't hurt to try............might want to take it to a electronic shop if you don't have the equipment.........also I did bench test the DC volt evaporator motor before I decided to mess with the board and the motor was okay.

Something makes we wonder why the resistor and circuit pads burnt out. I assume the resistor was in series with the motor, and the relay was the device that turned on the motor.

Did the 2Watt have a good solid solder connection?

A bad solder joint may come apart from fridge vibrations, thus causing surges, but if that was the case, the resistor wuld be the last to go.

The fan may be pulling too much current?

If you happen to blow the resistor again, I would try the same thing, but maybe go with a wire wound resistor. Wire wounds are a little better for motor circuits.

Also, maybe lift a lead on the resistor and throw in a meter and see what the current is.

Current time is 08:55
