ApplianceRange
When 4D12 appears, Maytag’s range help directs attention to the door: the latch assembly on the oven door, the door switch, and the wiring associated with them. Any one of the three could be the source.
Four-part breaker reset
Step
What to do
1
Shut off the range’s breaker(s) and let a minute pass.
2
Flip the breaker(s) on to give the range power.
3
Observe the display for one minute; the code should stay away.
4
Verify that the oven works.
Should 4D12 reappear, a technician needs to inspect the door hardware.
Bay Area owners can reach us at (415) 649-2156 for Maytag range work; see Maytag range repair for what the visit covers. Mention 4D12, your model number and the reset you carried out.
Model compatibility: Maytag reuses codes across series and model years, so 4D12 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
