On the covered Maytag wall oven, F4 E6 means the microwave section of a combination wall oven has reported a fault First, open and close the microwave door firmly and reset the power at the breaker. Then: test the oven side and the microwave side separately, and book service if F4 E6 returns.
Differential
Likely causes of “Maytag wall oven code F4 E6”, and how to tell them apart
- 1
The microwave section of a combination wall oven has reported a fault
What separates it The display shows F4 E6 and the microwave side will not run
How to confirm Open and close the microwave door, then reset the power
- 2
A sensor in the microwave section that reads wrongly
What separates it Heating is uneven or stops early
How to confirm A technician tests the sensor in the microwave cavity
- 3
A loose connector in the microwave section
What separates it The code came after the oven was serviced
How to confirm A technician reseats the plugs
- 4
A door switch that did not register
What separates it The microwave door closes but the control disagrees
How to confirm A technician tests the door switches
- 5
A control board fault
What separates it Sensors and switches test well
How to confirm The board is replaced last
Before you touch a setting
Record this first — changing settings destroys the evidence
- That the display shows F4 E6
- Whether the oven side works normally
- Whether the microwave heats a cup of water
- The model number from the frame, which tells you whether your oven has a microwave section

Correct only the documented fault domain
ReversibleTest the oven side and the microwave side separately, and book service if F4 E6 returns. A power reset is the whole of what Maytag publishes for this code: remove power for 1 minute, restore it, and watch whether the code returns.
Open and close the microwave door
ReversibleOpen the microwave section's door fully and close it firmly until it latches, in case the control was only waiting for the door.
Reset the power at the breaker
ReversibleA wall oven is hard-wired, so switch it off at its breaker for a minute and then on.
Test the oven side
ReversibleSet a short bake on the oven cavity to see whether the oven works normally, which confirms that the fault is limited to the microwave section.
Test the microwave side
ReversibleHeat a cup of water for a minute. If it warms, the heating circuit is working and the code may have been a one-off.
Note which cavity was in use
ReversibleRecord what the oven and the microwave were doing when the code appeared, for the technician.
Book service if F4 E6 returns
ReversibleA technician checks the microwave section's sensors and the board and replaces the part at fault.
Model-specific
What is true of this model and not of its siblings
- The code on this page
- F4 E6, a microwave section fault on a combination wall oven.
- Parts involved
- The microwave sensors, the door switches and the control.
- Related
- F4 E0 to F4 E9 are in the same group.
Stop boundary
When this stops being a self-service repair
- !If F4 E6 returns after the door has been closed and the power reset, book Maytag service with the model number
- !Never open the microwave case; the capacitor stays charged
- !Wall ovens are hard-wired, so leave any wiring to a licensed technician

Usually not; the oven and the microwave are separate circuits.
Can I reset it myself?+
Yes, with the breaker, but the repair of the microwave section is for a technician.
Is the microwave safe to use?+
If it heats normally and the code clears, yes, but never open the case.
Is it the same as F4 E0 to F4 E9?+
They are neighbors in the same microwave group, each naming its own sensor.
