What F4 E5 means

F4 E5 is shown by Maytag built-in wall ovens that include a microwave. The code concerns the microwave weight sensor and the wiring that carries its signal. Weight sensing lets some programs estimate the amount of food and set the cook time. If the control cannot read that sensor, it reports F4 E5 on the display. Defrost by weight and similar programs are the likeliest to stop working, while manual timed microwave cooking and normal oven baking may carry on without trouble.

Common causes of F4 E5

  • The microwave weight sensor
  • The wiring from the sensor to its board
  • The control that reads the signal
✓ One safe check you can try

1. Turn the oven's breaker off and leave it for one minute. 2. Turn it on again. 3. Wait a minute and look at the display for F4 E5. 4. If it is gone, remove everything from the microwave cavity and run a short timed cycle with a cup of water to see that it heats.

! Why to stop there
  • A heavy item left on the tray or a worn connector can both look the same from the outside, so we need to test the circuit
  • We do not replace a sensor on a guess
  • Price in writing before work starts, then 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.

F4 E5F4 E5 questions
Will the microwave still heat food with F4 E5?

Often it will in manual mode, since the weight sensor serves automatic programs. After the reset, try a timed run. If the microwave will not start at all, tell us so we can look wider.

Could a heavy dish cause F4 E5?

The code points to the sensor circuit, not to the weight of a dish. Still, remove everything and run the reset once with the cavity empty to rule out a one-time reading problem.

Do you repair older built-in microwave ovens?

Yes. Many are well past warranty and still in daily use around Houston. We test, quote in writing, and tell you if the repair is not worth the money.
