Maytag Refrigerator Error Code 25
Defrost cycle ran too long
What this error means
Code 25 appears when a defrost cycle exceeded the maximum allowed time without the evaporator thermistor reporting thaw completion.
How 25 is detected
Maytag refrigerator models lock the door or lid before energizing fill, heat, or high-speed spin. 25 means the latch switch never sent a "locked" signal to the main control, or the lock motor did not complete its travel. On Maytag MFF2055FRZ, Maytag MFI2570FEZ, and similar variants, clothing caught in the gasket, a misaligned strike, or a failed latch assembly are the most common mechanical causes—not the board itself.
Inspect the door gasket perimeter and strike alignment before replacing the latch. Heavy ice load requiring extended manual defrost is reported frequently on this code. After correcting mechanical issues, manually defrost the freezer with power off and doors open 24 hours. If the latch clicks but 25 persists, the door lock switch or wiring harness to the control board likely needs testing with a multimeter.
Do not force the door open during an active cycle; wait for the lock to release when the board de-energizes the lock motor—usually two to three minutes after canceling power on most Maytag units.
Common causes
- Heavy ice load requiring extended manual defrost
- Defrost thermistor giving false cold readings
- Heater partially open producing slow thaw
- Main control defrost timer logic fault
Step-by-step fixes
- 1Manually defrost the freezer with power off and doors open 24 hours
- 2Inspect the thermistor clipped to the evaporator for ice encasement
- 3Verify the heater draws expected amperage during defrost
- 4Clear the drain pan tube before restarting
When to call a technician
Code 25 after full manual defrost and good heater amps may need main control or thermistor replacement.
Affected models
- Maytag MFF2055FRZ
- Maytag MFI2570FEZ
- Maytag MSS25C4MGW
Prevention & maintenance
- Wipe the door gasket weekly and avoid overloading items against the seal—25 often starts as a slow leak or latch misalignment.
- Record when 25 appears in the cycle and whether it clears after a 60-second power reset on your Maytag refrigerator—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for 25; Maytag uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting 25; reversed plugs on pumps and valves cause immediate repeat faults.
