Symptoms
• Oven will not heat or maintain temperature
• Display screen shows 'F00' error code
• Oven buttons and controls do not respond properly
• Bake, broil, or self-clean functions will not start
• Oven may beep repeatedly or continuously
• All indicator lights on display panel may be inactive
• Oven turns on and off unexpectedly during cooking
Possible Causes
• Faulty electronic control board (main PCB) failure
• Loose or corroded electrical connections inside the oven cavity
• Power supply failure to the control board
• Temperature sensor probe disconnected or failed, sending erratic signals
• Damaged wiring harness between control panel and heating elements
• Tripped or failing 240V household circuit breaker serving the oven
• Improper 240V electrical connection at the wall outlet (USA standard requirement)
• Control panel buttons stuck or damaged causing false inputs
• Failed relay or capacitor on the control board
Safety Checks You Can Do
• Allow the oven to cool completely for at least 30 minutes before attempting any troubleshooting
• Check your home's circuit breaker panel and confirm the 240V dedicated breaker serving the oven is in the ON position; if tripped, switch it fully OFF then back ON
• Perform a hard reset by switching off the circuit breaker for the oven for 60 seconds, then switch it back ON to clear temporary electronic errors
• Verify the oven is plugged into a dedicated 240V outlet as required by USA electrical codes and that the plug connection is firm and fully inserted
• Visually inspect the oven door latch and seal for damage, cracks, or misalignment, especially if the error appeared after running the self-clean cycle
• Look inside the oven cavity for any visible loose wires, disconnected connectors, or corroded terminals that you can safely observe without disassembly
• Check the temperature sensor probe (located inside the oven, usually near the back wall) for visible damage, cracks, or loose connections you can see from the oven opening
• Ensure no objects are blocking the oven door from closing completely, which can cause control board stress
• Wait 24 hours after performing the hard reset to see if the error reappears, as some transient faults may be temporary
• If the error persists after these checks, the control board or internal components likely require professional service
Safety First
Always disconnect the appliance from power before performing any checks. If you are unsure about any step, please contact a qualified technician.
