I have a Whirlpool refrigerator model WRF560SEYM04 (bottom freezer). The refrigerator is not maintaining temperature, but the freezer is working fine. I cleaned the condenser coils, which were fairly dirty, and went to check the evaporator fan motor operation. When I removed the back of the freezer to get to the evaporator fan, the upper right side had a big ice chunk around the two copper pipes going up into the actual refrigerator. Using a hair dryer I melted the ice. When it was plugged in again, the evaporator fan activated. I reassembled the freezer and plugged everything back in again.
I wasn't expecting to find the ice chunk. Is that something I should be worried about? Would the ice have caused the initial problem of the refrigerator not maintaining temperature, but the freezer working?
