Maytag Microwave Error Code F6 — Relay Board Failure
What this means
The F6 error code indicates a failure of the relay board or its associated wiring. The relay board controls power delivery to the magnetron and other high-voltage components. When it fails, the microwave may not heat food, may run without heating, or may display the error and refuse to start.
Alternate codes: F-6, F6E0
Step-by-step fix
4 stepsReset the microwave
Turn off the circuit breaker for the microwave for 1 minute, then restore power. This may clear a temporary relay glitch.
If the error clears and does not return, the issue was likely transient.
Monitor for recurrence
Use the microwave normally and watch for the error to return. If it reappears during heating, the relay board has an intermittent failure.
Note what function you were using when the error appeared — this helps diagnose which relay is failing.
Do not attempt internal repairs
Microwave ovens contain high-voltage capacitors that can deliver a lethal shock even when unplugged. Do not open the microwave cabinet unless you have specific training.
Microwave capacitors can hold a charge of 2,000+ volts even after unplugging.
Schedule professional service
Contact a qualified appliance technician to diagnose and replace the relay board.
Relay board replacement is the most common fix for F6 errors.
When to call a professional
Always call a professional for microwave internal repairs. The high-voltage components inside microwaves are extremely dangerous.
