Range repair for Bay Area homes
A slow cooling fan on a Maytag oven is part of our Maytag range repair work in San Francisco and around the Bay. Ring (415) 649-2156, quote 4D21 and the model number, and say whether the reset cleared the display for a while.
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.
Plain language
What this code means
The oven cooling fan is running too slowly; an airflow restriction, the fan or its wiring may be the cause.
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.
