Error codeF9 / F9 E0
ApplianceWall Oven
F9 and F9 E0 are one message
Display: F9 or F9 E0, treated alike.
Usual cause: wrong wiring at the home electrical supply or at the hard-wire connection.
Owner action: reset the power.
Wiring questions: a qualified electrician.
Three situations behind the code
Recent installation. If the oven went in within approximately 3 months, have a qualified electrician verify the supply. Every terminal needs correct wiring, and L2 and N must not be swapped.
Power outage. Unexpected line noise during an outage can be read by the control as an incorrect voltage amount. The same event may bring up PF.
Early keypress. Pressing a pad during the 10-second delay at power-up can produce the same code.
Resetting the oven
Switch the circuit breaker off for one minute, then switch it on. Watch the oven for 1 minute to see that the code stays gone, and check that it operates. If F9 returns, follow the wiring check described above.
Maytag wall oven service in San Francisco and around the Bay is booked on (415) 649-2156. When you phone, mention F9 or F9 E0, the model number, and whether the oven is newly installed or the code followed an outage. See Maytag wall oven repair for the overview.
Model compatibility: Maytag reuses codes across series and model years, so F9 / F9 E0 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F9 and F9 E0 most often indicate the oven is wired incorrectly at the home electrical supply or the hard-wire connection.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
