GE Refrigerator Error Code 0200

Code 0200 means the freezer defrost heater ran longer than the control board's allowed time limit without completing a successful defrost cycle. The board monitors the FZ evaporator thermistor to know when the coils have reached the defrost termination temperature. When that signal never comes within the timeout window, the board logs 0200. The root cause is usually a bad evaporator thermistor, a failed defrost heater, or a faulty defrost thermostat.

You can use it in the short term, but continued operation without addressing the fault will lead to frost accumulation on the freezer evaporator coils. As frost builds up, airflow through the evaporator becomes restricted, causing the freezer and fresh food sections to gradually lose cooling ability. If the refrigerator is no longer maintaining safe temperatures (below 40 degrees F in the fresh food section), do not rely on it to store perishable food until the fault is repaired.

Yes, a damaged or poorly sealing freezer door gasket can contribute to code 0200. When warm air leaks into the freezer continuously, frost builds up faster and heavier than the defrost system is designed to handle. The defrost heater cannot melt the excess frost within the normal cycle time, triggering the timeout. Inspect the door gasket by closing the door on a piece of paper and pulling it out. If there is no resistance, the gasket is not sealing properly and should be replaced.

Start by checking whether fault code 0004 is also present, which would point directly to the FZ evaporator thermistor as the problem. If 0004 is active, test the thermistor resistance and compare it to the spec in your model's service manual. If the thermistor checks out, test the defrost heater for continuity and the defrost thermostat for continuity when cold. Replace whichever component tests as open or out of spec. Also inspect the door gaskets for gaps that could be causing excess frost.

If the FZ evaporator thermistor is the cause, the part typically costs between $15 and $40 and is a manageable DIY repair requiring removal of the freezer back panel. A defrost heater assembly generally runs $20 to $60 in parts. A defrost thermostat is usually under $20. If you hire a technician, expect a service call fee of $75 to $150 plus labor, which can bring the total to $150 to $300 depending on which component has failed and your location.
