evap coils frozen. replaced bi metal defrost thermostat and defrost heater and coils will freeze up again after 4-5 days . Is there a defrost timer for this model or should I be checking or is it something else? any help would be great. Thank You Brian
Go to web site %url% There are two proceedures there to manually force defrost, one should work. If it fails to defrost, replace the control board, this contains the adaptive defrost circuit. It must be there as there is no other pc board in the fridg.
