Maytag Microwave Error Code F6 E6

F6 E6 indicates that the oven appliance manager, controlled by the GOC AM board, has lost communication with the rest of the control system. This is typically related to a failure in the 13.7 VDC supply from the SMPS, a wiring fault between the power supply and the GOC AM board, or a loss of 120VAC input to the appliance. The microwave will not operate normally until the communication link is restored.

No, you should not attempt to use the microwave while this error is active. The F6 E6 fault indicates a communication failure within the control system, and the appliance has shut down as a safety measure. Attempting to bypass or ignore this fault could lead to unpredictable operation or additional component damage.

Repair costs depend on which component has failed. If only a wiring harness needs reseating, the cost may be limited to a service call fee, typically in the range of $75 to $150. Replacing the SMPS or GOC AM board will add parts costs that can range from $100 to $300 or more depending on the specific model, plus labor. In some cases, the total repair cost may approach or exceed the cost of a replacement unit.

Some causes of F6 E6, such as a tripped circuit breaker or a loose wiring harness connector, can be addressed without replacing parts. However, diagnosing this fault properly requires a multimeter to check DC and AC voltages at specific test points on the GOC AM board. Work involving internal microwave components carries serious electrical hazards, including high-voltage capacitors that retain charge even when unplugged, so this repair is best handled by a qualified technician.

A reset by unplugging the unit for a few minutes may temporarily clear the error, but it will return if the underlying cause is not corrected. If the SMPS is not delivering proper voltage, the wiring harness is damaged, or the GOC AM board is faulty, the fault will reappear once the microwave restarts. A reset is only useful as a first step to confirm whether the issue is intermittent.
