Differential
Likely causes of “Whirlpool wall oven code F4, F4 E0, F4 E1, F4 E2, F4 E3, F4 E4, F4”, and how to tell them apart
- 1
The microwave inverter (F4 E0, F4 E8, F1 E5)
What separates it The microwave side will not heat and the code is one of these
How to confirm Whirlpool names the microwave inverter (and the magnetron tube for F1 E5) or the associated wiring
- 2
A microwave thermistor or sensor (F4 E1, F4 E2, F4 E3, F4 E4, F4 E5, F4 E6, F1 E6)
What separates it The microwave side reports a sensor fault on the display
How to confirm Whirlpool names, in turn, a thermistor, a sensor/thermistor, the exhaust air temperature sensor, the humidity sensor, the weight sensor, the waveguide temperature sensor and the microwave thermistor
- 3
The microwave appliance manager, user interface or power relay (F1 E2, F1 E3, F1 E4, F6 E7, F6 E8)
What separates it The microwave controls do not respond when you touch them
How to confirm Whirlpool names the microwave user interface, the microwave appliance manager or its power relay, and the wiring
- 4
A microwave meat probe or its receptacle (F4 E7)
What separates it The code appears when the microwave probe is used
How to confirm Whirlpool says to verify the microwave meat probe is seated and not to use the oven meat probe in the microwave, as they have different resistance values
- 5
The microwave door not seen by the control
What separates it Door in Microwave Display shows on the control panel
How to confirm Whirlpool says to open and close the door because the control is looking for input from the door switches
Before you touch a setting
Record this first — changing settings destroys the evidence
- The exact display, such as F4 E0, F4 E7, F1 E5 or Door in Microwave
- Whether only the microwave side is affected or the whole unit
- Whether the microwave meat probe was in use

0 of 6 completedWhat to do first
ReversibleOpen and close the microwave door and reset the power.
Correct only the documented fault domain
ReversibleArrange service for the microwave component the code names. A power reset is the whole of what Whirlpool publishes for this code: remove power for 1 minute, restore it, and watch whether the code returns.
Open and close the door
ReversibleFor Door in Microwave Display, Whirlpool says to open and close the door because the control is looking for input from the door switches, then give a one-minute breaker reset.
Reset the power
ReversibleFor every code on this page Whirlpool gives a one-minute breaker reset: turn the circuit breaker off for one minute, turn it on, and monitor the oven for one minute to make sure the code does not return.
Check the microwave meat probe
ReversibleFor F4 E7 verify the microwave meat probe is securely inserted in its receptacle and use only the microwave probe, not the oven probe.
Arrange service for the component named
ReversibleWhirlpool publishes no repair beyond the reset for the inverter, sensors and managers; a code that returns needs a technician with the model's tech sheet.
Model-specific
What is true of this model and not of its siblings
- Displayed as
- F4, F4 E0 to F4 E9; F1 E2 to F1 E6; F6 E7, F6 E8; Door in Microwave Display.
- Parts named
- Microwave inverter; magnetron tube; microwave appliance manager; microwave user interface; thermistors and sensors; meat probe; power relay.
Stop boundary
When this stops being a self-service repair
- !Do not open the microwave section or touch the inverter or magnetron; they hold high voltage even when the unit is off
- !Turn off the breaker and arrange service for any code that returns after the reset

the microwave side of a combination wall oven reported a fault, or the control is waiting for the microwave door
What are the F4 E codes on a combination wall oven?+
Microwave-side codes: F4 E0 and F4 E8 the microwave inverter, F4 E1 a thermistor or the appliance manager, F4 E2 the microwave sensor or thermistor, F4 E3 the exhaust air temperature sensor, F4 E4 the humidity sensor, F4 E5 the weight sensor, F4 E6 the waveguide temperature sensor and F4 E7 the microwave meat probe.
What are F1 E2 to F1 E6?+
F1 E2 the microwave user interface, F1 E3 the microwave appliance manager, F1 E4 the appliance manager or power relay, F1 E5 the inverter or magnetron tube and F1 E6 the microwave thermistor or sensor.
What is F4 alone?+
Whirlpool names the oven cavity control or the wiring.
Is it safe to use the oven side?+
Whirlpool does not say; keep the microwave side off until the code is cleared and use the oven side only if the unit otherwise works.
Does this apply to Maytag, KitchenAid and JennAir combination units?+
Yes, on the same platform.
