I have 7 year old Kenmore/Frigidaire top freezer refrigerator. It been really hot lately, compressor runs about 90% of the time but does maintain
35F in fresh food compartment as long as evaporator is frost free. Problem is that evap coils keep frosting over and I have to defrost these manually. I have replaced defrost timer and checked the heater/thermostat circuit(measures 33ohm )to be good. Is it possible that the excessive on-duty cycle produces frost faster than system can remove it? Have any experts seen an problem like this? Thanks , in advance George Raetz- posted
