Frigidaire Oven Error Code F31
Shorted oven temperature sensor
Common Causes
- 1Probe element internally shorted, reading collapsed-low
- 2Melted lead insulation shorting the run to the cavity wall
- 3Moisture bridging the sensor plug pins
Step-by-Step Troubleshooting
- 1
F31 is the collapsed-low twin of the open-sensor fault: here the board sees resistance far below the room-temperature figure, which it interprets as a wildly hot cavity, so the oven balks or trips instantly
- 2
Kill power and meter the probe across its pins — a reading crushed down toward a handful of ohms confirms the element has shorted inside and the probe is done
- 3
If the probe meters correctly once unplugged from its lead, the short lives in the wiring: hunt for melted or pinched insulation where the run grazes the hot cavity wall and grounds out
- 4
Dry and inspect the connector shell too, because condensate bridging two pins mimics a shorted probe until the plug dries out
Pro Diagnostic Tip
The tell of a short versus an open is which way the reading breaks: F31 collapses the resistance low so the board thinks the oven is already scorching and refuses to fire. Unplug and meter the probe alone — a normal reading there pins the blame on a grounded lead, not the sensor.
