Leyland L for Model Number zlss480D

Answer Leyland, Did you check or replace the evaporator thermo disc, mounted on the evaporator under the evaporator sensor ? And did you actually test the resistance of the defrost heater (38 ohms). And, you are sure the door is closing and sealing, especially at the top of the door. You should also check the pan heater resistance (330 ohms). We'll be sending you some additional information.
