Electronic oven control beeps and displays F1, oven functions disabled or erratic temperature control.

Safety first: Turn the range OFF at the breaker and allow it to sit for at least 5 minutes before touching any wiring. Do not work on the unit while it is energized.

• Power reset: Switch the range off at the household breaker for 5–10 minutes, then restore power. If F1 returns immediately, the fault is likely permanent.
• Inspect control panel: Remove the backguard/rear panel screws to access the electronic oven control (EOC) and keypad ribbon cable. Look for signs of moisture, grease, or corrosion on the ribbon connector.
• Reseat ribbon cable: Gently unplug the keypad ribbon from the EOC, wipe the contacts with a dry, lint‑free cloth, and reconnect firmly.
• Check for stuck keys: With power restored, press each keypad button individually. If the code reappears when a specific key is pressed, the touchpad is shorted.
• Replace parts as needed: If F1 persists after cleaning and reseating, replace the control panel touchpad assembly or the electronic oven control board as a matched set according to the Thor Kitchen parts diagram for your model.
