What F3 means

F3 on Frigidaire convection microwaves, such as FPMO209KF, is read as a key short error. The control sees one of the touch pads as shorted, as if a key were being pressed all the time. The pads may not respond normally, and the keypad is the repair that is usually needed. This is our plain reading of the code, and we confirm it on site.

Common causes of F3

  • A shorted or damaged touch pad
  • Moisture under the keypad
  • The control board or its connection
✓ One safe check you can try

1. Wipe the pad surface with a dry soft cloth. 2. Make sure nothing is resting on the pad. 3. Try a few pads gently. 4. If F3 returns, call us to schedule service. 5. Keep liquids away from the touch panel and avoid pressing hard on the pads.

! Why to stop there
  • F3 tells us a key reads shorted but not whether it is the pad, moisture or the board.
  • We check the pad and its connection before we recommend a replacement.
  • We give the price in writing and tell you plainly if an older microwave is not worth it.
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.

F3F3 questions
What does a key short mean?

The control reads one of the touch keys as always pressed. That can come from a damaged pad or from moisture. Pads can short from moisture, grease or wear.

Can I use the microwave with F3?

The pads may not work normally, so it may be difficult. Do not keep pressing buttons. If wiping does not help, the pad needs to be checked.

Do you repair touch pads?

Yes. We repair microwave controls and tell you plainly if it is not worth it. The control board is tested after the pad. Tell us whether any pad works normally, since that narrows the cause to the pad area.
