Frigidaire Oven F10 Error: Runaway Temperature Explained

F10 on a Frigidaire oven means the oven detected a higher than normal temperature. Frigidaire calls it thermal runaway, and it is a built-in safety alert. Turn the oven off and let it cool. Then reset it by cutting power for up to 30 seconds, either by unplugging the range or turning off its breaker. If F10 comes back, have the oven checked before you use it again.

What F10 means

Frigidaire describes F10 as the oven detecting higher than normal temperatures, a safety alert meant to protect the appliance. In practice, the control board either thinks the oven is hotter than it should be, or is not getting a believable reading from its temperature sensor, so it stops heating and shows the code.

What to do right now

1. Turn the oven off and let it cool before doing anything else.
2. If the oven keeps heating even though it is off and showing F10, turn off the range at the circuit breaker right away. Do not wait for it to cool first.
3. Once it has cooled, reset the range by disconnecting power for up to 30 seconds. Unplug it, or switch the breaker off and back on.
4. Try a normal bake at a moderate temperature and stay nearby.

An oven that keeps heating after it has been turned off is a safety problem, not an annoyance. Our guide on what to do when an oven will not turn off covers that situation step by step.

What usually causes F10

When F10 keeps coming back, technicians usually look at three things:

• The oven temperature sensor. A sensor that reads wrong can make the control think the oven is overheating. Technicians test its resistance against the spec on the range's tech sheet.
• Wiring and connectors between the sensor and the control board, which can loosen or burn over time.
• The control board. A relay that sticks closed can keep an element powered, which is the dangerous version of this problem.

All three involve testing live electrical parts, so this is a job for a technician.

Is it safe to keep using the oven?

Not if F10 comes back. A single F10 that clears after a reset and never returns may have been a glitch. A repeating F10 means something in the temperature control system is not working, and that system is what keeps your oven from overheating. If your Frigidaire has the opposite problem and will not get hot enough, see our guide to a Frigidaire oven that is not heating.

Other Frigidaire range codes you might see

F10 is not the only code a Frigidaire range can show. Frigidaire's own support library lists, among others, F3 and F20 as communication errors and F40 and F41 as a cooktop lockout. Codes and their meanings can differ by model, so the Frigidaire range error code guide is the place to confirm any code on your display.

A useful rule for any oven code: if the oven is behaving normally after a reset and the code never returns, it may have been a one-off glitch. If the same code keeps coming back, something is failing and it will not fix itself.

Getting it fixed

If you are in Fairfield or anywhere in Solano County, California, we can connect you with a local technician who works on Frigidaire ranges. Our oven repair page explains how the referral works. If your range is still under warranty, contact Frigidaire first.

Frequently asked questions

How do I clear an F10 code on a Frigidaire oven?

Let the oven cool, then disconnect power for up to 30 seconds by unplugging it or turning off its breaker. Frigidaire recommends contacting support if the problem continues.

What does thermal runaway mean?

It means the oven detected a temperature higher than it should be. The code stops heating as a safety measure.

Can a bad temperature sensor cause F10?

Yes. A faulty sensor is one of the most common causes, because the control relies on it to know how hot the oven is.

Should I keep using my oven with an F10 code?

No, not if it returns after a reset. Have the temperature sensor, wiring, and control board checked first.
