Frigidaire Oven F1 — Runaway Temperature / Stuck Key (Older Models)
Frigidaire Oven · Error code F1
What F1 Means
On older Frigidaire ovens this single-digit F1 indicates either a runaway oven temperature condition (sensor reads way above target) or a stuck key on the touchpad. The control shuts down heat.
Symptoms
- F1 with continuous beeping
- Oven reaches temperatures higher than set
- Touchpad button feels mushy or stuck
Common Causes
Membrane switch shorted from grease or wear.
Sensor reading falsely high.
Control mis-reading the sensor or with a welded bake relay.
Relay stuck closed causing actual runaway heat — safety critical.
How to Fix It
- Cut power at the breaker immediately if the oven is hot — do not keep using it.
- Disconnect the touchpad ribbon from the EOC and restore power — if F1 clears, replace the touchpad.
- Test the oven sensor at room temp — should read ~1080 ohms.
- If the bake element glows after power is cut to the EOC bake relay, the relay is welded — replace the EOC.
- Replace the EOC if the keypad and sensor test good.
