Error code9D21
ApplianceRange
Maytag lists 9D21 for ranges and blames the oven door: its latch, its switch, or the wiring that belongs to them. These are possible causes, not confirmed ones.
Resetting, start to finish
Begin with the breaker(s) in the off position and let a minute go by.
Move them back to on.
Check the display for sixty seconds, looking for 9D21.
Use the oven to confirm it works.
Another 9D21 after that means booking a technician to inspect the door hardware.
Call (415) 649-2156 to set up Maytag range repair in San Francisco or elsewhere around the Bay. Note 9D21, the model number and the results of your breaker reset first.
Model compatibility: Maytag reuses codes across series and model years, so 9D21 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
A fault may exist in the oven door latch, the door switch or the wiring that belongs to them.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
