Maytag Refrigerator Error Codes
15 error codes with causes and fixes
- 22Freezer evaporator fan not runningCode 22 on Maytag French-door and side-by-side refrigerators means the freezer evaporator fan did not report rotation. Cold air stops circulating from the freezer into the fresh food section.
- 23Defrost heater circuit openCode 23 indicates the adaptive defrost system detected an open defrost heater circuit. Frost will accumulate on the evaporator until airflow fails.
- 24Defrost thermostat open during defrostCode 24 means the defrost thermostat did not close when the heater energized. The board interprets this as a failed defrost temperature path.
- 25Defrost cycle ran too longCode 25 appears when a defrost cycle exceeded the maximum allowed time without the evaporator thermistor reporting thaw completion.
- 26Compressor relay or start device faultCode 26 means the compressor did not start when the control energized the start device. Both sections warm when the sealed system is not pumping.
- 27Freezer thermistor signal faultCode 27 means the freezer compartment thermistor sent an out-of-range signal. Defrost timing and compressor run length depend on accurate freezer temperature feedback.
- 28Fresh food compartment thermistor faultCode 28 indicates the refrigerator section thermistor failed. The control may over-cool or under-cool the fresh food area without valid readings.
- 29Ice maker optics or position faultCode 29 appears on models with optical ice level sensing. The control cannot confirm ice maker position or bin level.
- 30Refrigerator damper stuck closedCode 30 means the motorized damper between freezer and refrigerator did not open. The fresh food section warms while the freezer may still cool.
- 31Dispenser ice door motor faultCode 31 means the in-door ice chute flap did not open or close on command. Cubes may jam or warm air enters the freezer through the chute.
- 32Dispenser water valve or switch faultCode 32 indicates the dispenser water system failed—valve, switch, or heater circuit on chilled-water models.
- 33Water filter status or flow faultCode 33 relates to the water filter circuit—either excessive restriction, missing filter, or RFID mismatch on models with filter sensing.
- 34Sealed system performance faultCode 34 means the control detected poor cooling performance consistent with a sealed system issue—low refrigerant, restriction, or weak compressor pumping.
- 35User interface board communication faultCode 35 means the dispenser or console UI lost communication with the main control. Temperature displays and ice/water requests may freeze.
- 36Main control to UI serial link faultCode 36 is a broader communication fault between the main machine control and distributed boards—UI, ice maker, or damper modules.
