Maytag Refrigerator Error Code 29
Ice maker optics or position fault
What this error means
Code 29 appears on models with optical ice level sensing. The control cannot confirm ice maker position or bin level.
How 29 is detected
Maytag refrigerator models lock the door or lid before energizing fill, heat, or high-speed spin. 29 means the latch switch never sent a "locked" signal to the main control, or the lock motor did not complete its travel. On Maytag MFI2570FEZ, Maytag MSS25C4MGW, 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. Ice mound blocking the emitter and receiver LEDs is reported frequently on this code. After correcting mechanical issues, level the ice in the bin below the sensor path. If the latch clicks but 29 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
- Ice mound blocking the emitter and receiver LEDs
- Misaligned optics boards after shelf removal
- Ice maker module stalled mid-rotation
- Loose connector at the ice maker head
Step-by-step fixes
- 1Level the ice in the bin below the sensor path
- 2Remove the ice maker cover and verify both optics boards face each other
- 3Manually rotate the ejector if a cube is jammed—power off first
- 4Press the feeler arm down to reset the harvest cycle
When to call a technician
Optics aligned with no ice obstruction but code 29 every harvest needs ice maker module W10884390 series service.
Affected models
- Maytag MFI2570FEZ
- Maytag MSS25C4MGW
- Maytag MFF2055FRZ
Prevention & maintenance
- Wipe the door gasket weekly and avoid overloading items against the seal—29 often starts as a slow leak or latch misalignment.
- Record when 29 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 29; Maytag uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting 29; reversed plugs on pumps and valves cause immediate repeat faults.
