As of last night I noticed the fan in my fridge would not shut off and ice maker was slow at making ice and things were getting soft in freezer and items in fridge were all sweaty and not cold enough.Temp in freezer is only 20 degrees and fridge is at 50 degrees,any suggestions?? I clean the bottom of the fridge twice a year.
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.
check defrost heater, defrost thermostat. How to check here>Refrigerator Repair Guide: How To Fix a Refrigerator - ACME HOW TO.com
If the heater and thermostat are ok it’ll be the control.
