Frigidaire Oven Error Code F3
Oven sensor open or shorted
Common Causes
- 1Cavity probe reading out of its resistance window either direction
- 2Broken or grounded probe lead
- 3Loose or corroded plug at the control
Step-by-Step Troubleshooting
- 1
Take F3 as the umbrella complaint — the board simply cannot trust the probe reading, and your first job is to sort which direction it has drifted before deciding what to replace
- 2
Meter the probe at its plug against the room-temperature figure: a reading that has run away toward over-limit means the element or lead has broken, while a reading crushed toward nothing means it has shorted
- 3
Ohm the lead separately from the probe so you can tell a bad element from a bad wire; a good probe with a dead lead is a cheap harness fix, not a sensor
- 4
Reseat the plug at the control and clean its pins, because a loose or filmed connector alone can push the reading out of the window and set F3 with a perfectly healthy probe
Pro Diagnostic Tip
F3 is the catch-all that fires whether the probe has broken open or collapsed short, so one resistance reading at the plug tells you both whether the probe is bad and which way it failed. Sort the element from its lead and its connector first — a good probe behind a loose plug fails this test for free.
