I am trying to troubleshoot the motherboard in my GE Profile Arctica Stainless Steel Side by side refrigerator. The motherboard (Part Number WR55X10942) was scorched at the top and it was obvious that the R6 resistor was blown. It is a 110 Ohm resistor right at top of the board next to the 47 mFD Capacitors on top.
Note this is NOT the 2 Ohm 1/4 W resistor which blows when something is wrong with the evaporator fan.
I checked the Compressor Relay. No blown out soldering and it checked OK. I also checked the 4 or 5 Kettler SPST Relays. They check out fine too.
So I replaced the R6 (110 Ohm) resistor and was hoping that it would work.
But no luck. The Compressor does not kick in. I know that the COmpressor OLP and Relay are good because I have checked the refrigerator with amother motherboard and it works fine. The refrigerator side interior light comes on. The Freezer Side light does NOT come on. And all the LCD displays for temperature controls are black - not lit up.
WHat other component should I check? What else could be worng. I have the fridge with me for a few days so I want to fix the motherboard just for fun...
