Frigidaire Oven Error Code F31

What Does Error Code F31 Mean on a Frigidaire Oven?

Oven temperature probe short circuit.

The oven temperature probe is reading near-zero resistance, indicating an internal short. This causes the oven to see a falsely high temperature and prevents safe heating operation.

1. 1
   Probe shorted internally 65% of cases

How to Fix Frigidaire Oven Error Code F31

1. 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. 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. 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.
