Maytag range code 4D21 reports a cooling fan speed that is too low, with an airflow restriction, the fan or wiring as possible causes.
Model compatibility: Maytag reuses codes across series and model years, so 4D21 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
What this code means
4D21
Cooling fan speed too low; there may be a problem with an airflow restriction, the Oven Cooling Fan, or the associated wiring.
Try this reset
First, take the range off power by switching off its circuit breaker(s) for a full minute (one minute). Then, turn the circuit breaker(s) back on to restore power. Next, check for one (1) minute that the code stays off the display. Last, verify operation of the oven.
Possible trouble spots
Cooling fan speed too low is how Maytag explains 4D21. The article lists an airflow restriction, the Oven Cooling Fan and the associated wiring as areas where a problem may exist.
A repeat of 4D21 after the reset means help is needed from service.
