KitchenAid Range Error Code F1 E4: Meaning and Fix
Also shown as: F1E4, F1-E4
Reading the range display
On a range or oven the fault appears on the clock or oven display, often with a beep. Press Cancel or Clear once to silence it, and write the code down first. KitchenAid pairs the number with a letter group in the manual, so match the exact characters.
KitchenAid is Whirlpool Corporation's premium appliance line. Its dishwashers, ranges, microwaves and refrigerators share Whirlpool boards but use their own panel layouts and numbering in the manuals. The codes apply to model numbers such as KUDS24SEWH1, KUDS01DJSS0 and KHMS155LSS4; check the label on your unit to confirm yours.
What causes F1 E4
- Magnetron is weak or has failed
- Relay or driver circuit on the control board is not closing
- High-voltage diode or capacitor is shorted or open
- High-voltage transformer or inverter board has failed
How to fix it
- Cycle the power: turn the range or oven breaker off for one minute, switch it back on, and run the function that showed the code.
- Before opening any panel, switch off the breaker or unplug the appliance; this circuit can carry line voltage.
- Unplug the microwave and wait at least five minutes; the high-voltage capacitor can hold a dangerous charge.
- Do not remove the cabinet to probe the high-voltage section unless you are trained; the capacitor can be lethal.
- Have a technician test the magnetron, diode, capacitor and transformer using safe discharge procedures.
- Replace the failed component, or weigh the repair cost against a new microwave on inexpensive units.
- Run a full short cycle or function again and confirm the code stays gone before putting the appliance back into normal use.

Questions
What does F1 E4 mean on a KitchenAid range or wall oven?
It is a fault code from the KitchenAid control. It indicates a problem with the microwave power section. A power reset is the first thing to try.
Can I keep using the range or wall oven while it shows F1 E4?
Stop using it until it has been checked. This fault involves heat, high voltage or sealed-system parts, and running it can damage the appliance or create a safety risk.
Do I need a technician to clear F1 E4?
Often yes. Part of this repair means testing live circuits or replacing a control board, so a technician is the safer choice unless you are comfortable with electrical diagnosis.
