Not working, ER and CO in spots for temp. French doors bottom freezer, water and ice on door. Called customer sercvice, was told to turn off circuit breaker. Fridge started working. cleaning in back of, had significant dust on vent. still working 32 hours later. Was the dust the problem or do I need a new board?
ER CO is an indication of a communication error between the display board and the main board. Has this unit had a board replaced recently? If so, one of the multi pin plugs may have not gotten connected firmly, or an incorrect board may have been installed. The problem has nothing to do with the dust.

Nothing has been replaced. Brought it in August 2008. Is it normal for a board to be replaced in 2.5 years?
