Electronic oven control beeps and displays F1, oven will not start or cancels shortly after starting.

Safety first: Disconnect power at the breaker before removing any panels. High voltage is present even when the oven is off.

Steps to try:

• Power reset: Turn the oven off at the breaker for 5–10 minutes, then restore power. If F1 returns immediately, the fault is likely permanent.
• Inspect control panel: Remove the front control panel bezel (usually from inside the door frame or from the back, depending on model). Check the keypad ribbon cable where it plugs into the electronic oven control (EOC) for corrosion, moisture, or burnt spots.
• Clean and reseat ribbon: Gently unplug the ribbon, wipe contacts with a soft dry cloth or electronics contact cleaner, and firmly reseat it.
• Isolate keypad vs board: If possible, disconnect the keypad ribbon from the EOC, restore power, and see if F1 reappears. If F1 appears with keypad disconnected, the EOC is likely bad. If F1 only appears with keypad connected, the keypad is likely shorted.
• Replace failed part: If cleaning and reseating do not help, replace the faulty keypad/control panel assembly or the EOC according to the above test. Transfer wires one at a time to the new board to avoid miswiring.

When to stop: If you are not comfortable working around live wiring or removing the front panel, contact a qualified BlueStar technician.
