What does Maytag microwave error code F5 mean?

Error code F5 means the control board in your Maytag microwave has an internal failure. Try unplugging for 10 minutes. If the error persists, the board needs replacement. Compare the repair cost to a new microwave — replacement may be more cost-effective.

Maytag Microwave Error Code F5 — Control Board Failure

Professional Required Professional service required Tools: None (professional repair recommended)

What this means

The F5 error code on Maytag microwaves indicates the main control board has suffered an internal failure, typically involving the EEPROM memory chip or a critical processing component. The microwave will not function until the board is replaced. This is most often triggered by power surges, electrical storms, or general component aging.

Step-by-step fix

3 steps

Reset the microwave

Unplug the microwave for 10 minutes to allow a complete discharge and reset. Plug it back in and check if the error clears. Some board glitches can be resolved with a full power cycle.

If the error appeared during a power surge or storm, a reset has a reasonable chance of working.

Check the power source

Make sure the microwave is on a dedicated circuit. If it shares a circuit with other appliances, voltage drops when they run can affect the control board. Consider adding a surge protector.

Kitchen countertop circuits are often 15-amp shared — microwaves on dedicated 20-amp circuits are less prone to board failures.

Evaluate repair vs. replacement

If the reset doesn't clear the error, the control board needs replacement. Get the board cost for your model and add expected labor ($100–$150). If the total exceeds 50% of a new microwave's cost, replacement is usually the better option.

Maytag microwaves typically last 8–10 years. If yours is near end of life, investing in a new unit with a warranty may make more sense.

When to call a professional

Control board replacement inside a microwave requires working near the high-voltage capacitor. This is a professional-only repair.
