Frigidaire Oven F1 Error Code: The Runaway Temperature

The Logic Verdict: Electronic Control Failure

The F1 error code is a critical safety alert. It usually means the Electronic Oven Control (EOC)—the brain of the oven—has detected a failure. This can be a “Runaway Temperature” (the oven thinks it’s getting hotter than it should) or a “Stuck Key” (the keypad thinks a button is being held down).

The Fix:

1. Test the Sensor: A bad temperature sensor can sometimes trick the board.
2. Replace the Board: If the sensor is good, the EOC board itself is fried and must be replaced.

Common Causes

• Failed EOC Board (Most Common): The relay on the board is stuck closed, causing the heating element to stay on indefinitely, or the processor has failed.
• Bad Temperature Sensor: The probe inside the oven is giving false resistance readings.
• Stuck Keypad: The touch overlay is shorted, sending constant signals to the board.

Step-by-Step Fix

Step 1: Test the Sensor (The Cheap Fix)

Before buying an expensive board, rule out the $20 sensor.

1. Access the Sensor: Open the oven door. The sensor is the metal rod sticking out of the back wall.
2. Test Resistance: You’ll need to pull the oven out and remove the back panel to access the sensor plug. Unplug it and use a multimeter.
3. The Reading: At room temperature, it should read around 1080 to 1100 ohms. If it reads significantly higher or has no continuity, replace the sensor.

Step 2: Replace the Control Board (The Likely Fix)

If the sensor tests fine, the EOC board is bad.

1. Safety First: Unplug the range.
2. Remove Back Panel: Unscrew the upper back panel to reveal the control board.
3. Transfer Wires: Take a picture of the wiring before disconnecting anything. Remove the wires from the old board.
4. Swap the Overlay:
   • Crucial Step: Most new boards do not come with the plastic faceplate (overlay).
   • You can try to peel your old one off with a heat gun (risky).
   • Or, buy a new overlay that matches your color (Black/White/Stainless).
5. Install: Screw the new board in, reattach the wires exactly as they were, and apply the new overlay.

Required Parts

1. Electronic Oven Control Board (The Fix) This is the brain that usually fails. Verify your specific model number, but this is the most common one for Frigidaire Gallery. Frigidaire Control Board (316557205)

2. Temperature Sensor (The First Check) If your sensor reads bad (not ~1100 ohms), replace this first. Frigidaire Oven Sensor (316217002)

Summary

1. Test the sensor resistance (should be ~1100 ohms).
2. Replace the sensor if bad.
3. Replace the EOC board if the sensor is good.

Step-by-Step Fix

1. Power Cycle: Unplug the oven or flip the breaker for 5 minutes.
2. Disconnect Touchpad:
   • Unplug power.
   • Access the back of the control panel.
   • Unplug the ribbon cable connecting the touch panel to the clock board.
   • Power the oven back on.
   • The Test: If the F1 code stops (and you just get a different code for “missing keypad”), then the Touchpad is the bad part. If the F1 code returns immediately even with the keypad unplugged, the Clock Board (EOC) is bad.
