Frigidaire Microwave Combination Code F44: Cooling Fan Speed Too High

Medium · inspection needed

Code: F44
Appliance: Range
Brand: Frigidaire
Warranty: 30-day workmanship

What F44 means

On Frigidaire range and wall-oven combinations with a microwave, F44 means the external cooling fan for the microwave is turning abnormally fast. The control compares the fan's speed with what it expects and shows F44 when the speed runs high, then may stop the microwave. You will see the code on the display, and the microwave may refuse to run even though the oven below it is fine.

Common causes of F44

The fan speed signal the control reads
The cooling fan motor
The wiring between the fan and the control
The control board that drives the fan

✓ One safe check you can try

1. Turn the microwave off. 2. Cut off power at the breaker or plug for up to 30 seconds, then turn it back on. 3. Try a short microwave run and watch for F44. 4. Do not take the housing apart.

! Why to stop there

A fast reading can come from the motor or from a bad speed signal, and those need different tests.
We check the fan and its signal, then the control that drives it.
You get a written price first, and a plain answer on whether an older combination is 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.

F44F44 questions

Is F44 as serious as F43?

Both stop the microwave as a precaution. F44 means the fan reads too fast, so we check the signal and the motor before replacing anything, because the signal is often the cheaper fix.

Can the oven still be used with F44?

Often the oven works while the microwave does not, but that varies by model. We would test both sections so you know exactly what you can and cannot use.

Will a reset clear F44?

It may, if the reading was a one-time glitch. If F44 returns, the fan circuit needs testing, and we begin with the fan's speed signal and wiring.
