Maytag Microwave F1 E1 / F1 E4 / F6 / F6 E0 / F9 Error Code

These codes share the same owner-safe boundary: record the exact display, use one Maytag power reset, and arrange qualified service if it returns. The display can narrow the electronic path for a technician, but it is not a parts-replacement diagnosis.

Applies to Maytag over-the-range microwave with an applicable electronic display

What the appliance detected

Detected condition

Maytag documents F1 E1, F1 E4, F6, F6 E0, and F9 as electronic execution/control-path faults that may involve the relay control board, appliance control board, or associated wiring depending on the exact display and model.

What may contribute

Possible causes

  • The relay control board may not be executing commands normally on applicable codes.
  • The appliance control board may not be executing commands normally on applicable codes.
  • Associated wiring or connectors may require professional diagnosis.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the display and confirm the model

    • Photograph or write down the exact display before changing anything: F1 E1, F1 E4, F6, F6 E0, F9.
    • Confirm the complete Maytag model number and compare the display with the owner documentation for that exact microwave.

  2. Try one Maytag power reset

    • If there is no smoke, burning odor, repeated arcing, visible door damage, active water intrusion, abnormal overheating, or repeated breaker trip, switch the microwave circuit breaker off for one full minute.
    • Restore power once, monitor the display for at least one minute, and verify normal operation without opening the cabinet.
    • If the code returns, stop using the microwave and request qualified service rather than repeating resets.

Actions not recommended

  • Do not remove the outer cabinet, control panel, vent housing, waveguide cover, or any service panel to chase an error code.
  • Do not touch or test the high-voltage capacitor, transformer, inverter, magnetron, internal fuse, interlock wiring, control boards, sensors, thermistors, relays, or internal harnesses.
  • Do not bypass, tape, bridge, defeat, or adjust the door-interlock system, and do not operate the microwave with a damaged or misaligned door.
  • Do not perform live-voltage, continuity, resistance, capacitor-discharge, or internal connector tests as an owner troubleshooting step.
  • Do not replace a keypad, sensor, thermistor, control board, relay board, or other internal part from the displayed code alone.

When to stop and request service

  • Request qualified microwave service if the code returns after the single Maytag one-minute power reset.
  • Leave power disconnected and arrange service immediately for smoke, a burning odor, repeated arcing, a repeated breaker trip, visible door or wiring damage, water near electrical parts, or abnormal heat that does not subside normally.
