Maytag Microwave Error Code F6 E0

F6 E0 indicates a lost communication fault between the oven user interface board and the GOC AM appliance control board. The two boards exchange signals continuously during operation, and when that link is broken the microwave logs this code and disables operation. The fault can stem from a wiring issue, a voltage supply problem, or a failed board on either end of the communication circuit.

Start by verifying 120 VAC input at pins P8-1 to P7-1 on the GOC AM board, then check for 13.7 VDC at pins P6-1 to P6-2. Next, inspect the orange wire at P6-4 for continuity and look for damaged or unseated connectors in the wiring harness between the GOC AM and UI boards. If voltage and wiring are correct, the UI board or GOC AM board will need to be replaced.

Repair costs vary depending on the root cause. If the issue is a wiring harness repair or a reseated connector, costs are minimal and mostly involve labor time. A replacement UI board typically runs in the range of $50 to $150 for the part, while a GOC AM control board can range from $80 to $200 or more. Professional labor adds to these estimates depending on your location and service provider.

A power reset by unplugging the microwave for one to two minutes may temporarily clear the code, but if the underlying cause is still present the error will return. A reset is useful for ruling out a one-time communication glitch, but persistent F6 E0 codes require hands-on diagnosis of voltages and wiring.

No. The F6 E0 fault means the control and display boards are not communicating properly, which can prevent the microwave from responding correctly to commands. Operating the appliance in this condition is not recommended, and the unit will typically lock out cooking functions until the fault is resolved.
