What F4 means

On Maytag built-in wall ovens, F4 refers to the oven cavity control and the wiring that goes to it. This is the electronics that runs one cooking cavity, not a sensor or a heating element on its own. The control may not be answering as it should, or a wire to it may be loose. You see F4 on the display and the oven may stop the cycle, refuse to start one, or heat unevenly. If your oven has a microwave section, other F4 codes with a second character cover that part separately.

Common causes of F4

  • The oven cavity control
  • Wiring and connectors between the cavity control and the main control
  • How the oven responds after power is cut and restored
✓ One safe check you can try

1. Find the circuit breaker for the oven and turn it off for one minute. 2. Turn it back on. 3. Look at the display for a minute to see if F4 returns. 4. If the display is clear, run a short bake and check that the oven heats and the clock keeps time.

! Why to stop there
  • A reset does not repair a control that is failing, so F4 may be back within days
  • The code points to the control and its wiring, and we separate those by testing
  • The price is written down before we begin, and our work comes with a 30-day workmanship warranty
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F4F4 questions
Is F4 the same as F4 E0?

No. Plain F4 refers to the oven cavity control. F4 E0 and the codes after it name specific microwave parts on combination ovens. Look at exactly what the display shows before you compare.

Can I run the oven with F4 showing?

If the breaker reset clears it and the oven heats normally, careful use is fine. If it comes back, stop using the cavity, because the control is not responding the way it should.

Does F4 mean I need a whole new oven?

Not by itself. The code points to one control and its wiring. We test first and quote the repair in writing, and we tell you honestly if an older oven is not worth the cost.
