What E-23 means

E-23 on Frigidaire convection microwaves, such as FPMO209KF, appears when the preheat temperature is not reached within 30 minutes. The microwave tried to preheat and could not get to the set temperature in that time. You will see E-23 and the preheat stops. Convection heating may be weak or not working. The handbook does not name which individual models carry this code, so we confirm your exact model on the visit.

Common causes of E-23

  • The convection heater
  • The oven thermal sensor reading
  • Airflow through the oven cavity
  • The control board
✓ One safe check you can try

1. Leave the door open and give the microwave time to cool. 2. Make sure the vents are clear. 3. Try a lower set temperature. 4. Should E-23 come back, call us to schedule service. 5. Do not run convection again until it is checked, and note the temperature you had set. 6. Keep the area around the microwave clear.

! Why to stop there
  • A preheat that never arrives could be from a weak heater, a sensor reading wrong or the board, which cannot be separated by checking the outside.
  • We test the heater and sensor in order.
  • We tell you plainly if the microwave is not worth repairing.
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.

E-23E-23 questions
Why does preheat take so long?

The microwave may not be heating the oven side well, or it may be reading the temperature wrong. The microwave cycle uses a different heating system from convection preheat.

Does E-23 affect plain microwave cooking?

Often not, since it is about convection preheat. If E-23 shows in oven modes only, the problem is on the convection side. The preheat limit is long, so the code usually means a real heating problem and not a slow start.

Do you repair this microwave?

Yes. We repair them and quote in writing first. We test the heater and sensor. Tell us which temperature you set and how long you waited, and bring that to the visit.
