Frigidaire Range Code F42: Control Software Mismatch

Medium · inspection needed

Code: F42
Appliance: Range
Brand: Frigidaire
Warranty: 30-day workmanship

What F42 means

On Frigidaire ranges with later electronic oven controls, F42 means the control's internal software configuration is wrong for the range it is in. The most common reason is that a replacement control was fitted that does not match the model. The range cannot run properly with the wrong setup, so you may see F42 as soon as power is applied, with the oven and keys unresponsive. It is not a heat or sensor problem.

Common causes of F42

A replacement control that does not match the range model
The control's saved configuration
The memory on the control

✓ One safe check you can try

1. Turn the range off. 2. Remove power from the range at the breaker or plug for a short time and restore it. 3. If the control was replaced recently, note who fitted it and when. 4. Leave the control panel closed.

! Why to stop there

F42 usually shows up after a control swap, so the history of the range helps us a lot.
We compare the control's part number against your range model and check its configuration.
A written price comes first, and we are honest about what the correct control costs for an older range.

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.

F42F42 questions

Why did F42 appear after a repair?

A replacement control that is not the right one for the model can carry the wrong configuration. We would compare its part number with your range before doing anything else.

Can a power reset fix F42?

Unlikely if the control is the wrong match, since the setup itself is the problem. A reset is still worth a try, because it costs nothing and rules out a simple glitch.

Do you correct this on older ranges?

Yes. Older ranges remain common in Houston, and we repair them. You get a written price, and we say plainly if it is not worth it.
