I have an AMANA refrigerator where the evaporator coils are frozen over.?

Question

Which probably means that the defrosting heater isn't working. How do I fix that?

The freezer part of the refrigerator isn't freezing anything.

more then likely the defrost er part of the cold control is bad.

Try using a blow dryer on the evaporator coils, might work, might not.

Answer 3

It could be either the defrost timer, defrost thermostat or the defrost heater.  If it needs replacing check out http://www.apwagner.com.  They should have a breakdown of a refrigerator somewhere there.
