Occasional erratic temperature swings in refrigerator
« on: August 30, 2011, 06:43:47 AM »

Working on GE Monogram refrigerator.  Occasionally, the refrigerator temperature will go up to 46F by itself but the freezer side will stay cold.  I checked the damper door operation and it's working fine.  The only thing I did is shut the breakers off to the unit to allow the control board to reset.

Any suggestions on what else I should be looking for??
