What Does Error Code F31 Mean on a Frigidaire Oven?

Oven temperature probe short circuit.

F31 fires when the control board reads near-zero resistance on the oven temperature probe (RTD) circuit, the opposite of the open-circuit condition that triggers F30. A healthy probe reads roughly 1,100 ohms at room temperature; a short makes the board interpret an impossibly high temperature, so it locks out heating for safety. The short can originate inside the probe itself, in wiring pinched against the metal cavity, or at the board's sensor input.

Models affected: Frigidaire electric and gas ovens/ranges with a resistance-based temperature probe, including models such as FCRE3052AS and FGGH3047VF

What owners report: Owners commonly report F31 appearing at power-up or partway into a bake cycle, sometimes right after the oven or a rack was moved, which can pinch the rear probe wiring. Swapping in a new probe usually clears it, though a stubborn short pinched against the chassis can mimic a failed probe.

What Causes Error Code F31?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

1

Probe shorted internally 65% of cases
2

Wiring pinched causing short to chassis 25% of cases
3

Control board sensor input shorted 10% of cases

How to Fix Frigidaire Oven Error Code F31

🔧 Easy DIY Est. time: 10–20 min

⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.

1

Test the probe

Disconnect the probe from the control board. At room temperature, it should read approximately 1,100 ohms. Near 0 ohms = shorted probe.

🔩 Multimeter
2

Inspect probe wiring

Look for pinch points where the wiring passes through the oven cavity. Even slight pressure against the chassis can cause a short.
3

Replace the temperature probe

A shorted probe cannot be repaired. The probe threads into the upper-rear oven wall — typically 1–2 screws. Pull 2–4 inches of wire slack through and connect the new probe.

How to Reset Error Code F31

After replacing probe, run a short 350°F bake cycle to confirm F31 is resolved.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

When to Call a Professional

If probe measures correctly and F31 persists after replacement, the control board sensor input has an internal short.

Average professional repair cost for this issue: $150–$320

Frequently Asked Questions

Can I keep using my Frigidaire Oven when error F31 appears? +

It is not advisable. The oven may still power on, but running it while F31 is active can worsen the sensor fault or damage related parts. Treat it as a soon-as-possible repair.

What most commonly causes F31 on a Frigidaire Oven? +

Across reported Frigidaire oven repairs, the most frequent is probe shorted internally (65% of cases), wiring pinched causing short to chassis (25%), then control board sensor input shorted (10%). Check them in that order before replacing any parts.

F31 keeps coming back after a reset — what should I check next? +

A reset only clears the stored F31 fault; if it returns, the sensor problem is still present. Move on to the physical checks — test the probe, then inspect probe wiring — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.

How much does it cost to fix Frigidaire Oven error F31? +

A DIY repair typically runs $25–$55 in parts, versus $150–$320 for a professional service call, so handling it yourself saves around $125. Expect the work to take about 10–20 minutes.

Which Frigidaire Oven models show error F31? +

F31 is documented on Frigidaire electric and gas ovens/ranges with a resistance-based temperature probe, including models such as FCRE3052AS and FGGH3047VF. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
