Error codeE03
ApplianceMicrowave
A keypad fault is what E03 stands for on a Maytag over-the-range microwave. The touch panel, also called the user interface, sent an error notice to the control board, so either the panel or the wiring that feeds it may be the weak spot.
Quick things you can do
The only owner step Maytag lists is a power reset. Run it in this order:
Shut off the microwave’s breaker and let sixty seconds pass.
Flip the breaker back on.
Stand by for another sixty seconds and watch that E03 stays off the display.
Make sure the microwave runs normally again.
When E03 keeps coming back
A code that returns after the reset points at the keypad or its wiring. That is a job for a technician visit, not for more resets.
Codes with a similar feel
E13: blames the control board or its wiring instead of the panel.
E11: a gas sensor report rather than a keypad one.
Bay Area owners can arrange a technician for an over-the-range unit through Maytag microwave repair or by phoning (415) 649-2156. Write down E03, the model number and the reset you ran before you ring.
Model compatibility: Maytag reuses codes across series and model years, so E03 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
The keypad (user interface) reported a problem to the control board.
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.
