I have a 10 year old Kenmore fridge with freezer at the bottom and condenser coil at the bottom. The temperature to both fridge and freezer are warmer than normal: Freezer 1C (34F) and fridge 8C (46F) with setting to max. I have checked for the following: There is airflow for both fridge and freezer - set the defrost timer to defrost cycle and after 30 min. compressor starts up Compressor works fine - condenser coils are clean - condenser fan is functioning - no abnormal noise detected Removed back panel of freezer: NO ice build up - defrost heater working (I see water droplets on the bottom portion of the fins) very little frost build up on the top portion only of the evaporator coil, bottom half is clean as a whistle) Replaced defrost thermostat 1 or 2 years ago. Don't know what else to check for.
