Gas ovens are equipped with a safety feature known as a flame failure device, which automatically shuts off the gas supply if the flame goes out. This is designed to prevent gas leaks and potential explosions. When you release the knob, the flame may go out, triggering the safety mechanism and cutting off the gas flow.
Common Causes and Solutions
1. Incorrect Knob Position
- Cause: The knob may not be fully turned to the “On” position.
- Solution: Ensure the knob is firmly pushed in and turned to the desired setting.
2. Faulty Thermocouple
- Cause: The thermocouple, a sensor that detects the presence of a flame, may be malfunctioning.
- Solution: Call a qualified technician to replace the thermocouple.
3. Dirty or Clogged Burner Ports
- Cause: Debris or grease buildup can block the gas flow to the burners.
- Solution: Clean the burner ports using a wire brush or a commercial oven cleaner.
4. Faulty Ignition System
- Cause: The igniter, which sparks the flame, may be weak or damaged.
- Solution: Check the igniter and replace it if necessary.
5. Gas Pressure Issues
- Cause: The gas pressure may be too low or too high.
- Solution: Contact your gas supplier to adjust the pressure.
6. Airflow Obstructions
- Cause: Inadequate airflow around the oven can cause the flame to extinguish.
- Solution: Ensure the oven is properly ventilated and remove any obstructions from the vents.
7. Loose or Damaged Gas Connections
- Cause: Gas leaks can occur due to loose or damaged connections.
- Solution: Inspect the gas lines and tighten any loose connections. If you suspect a leak, contact a professional immediately.
Additional Troubleshooting Tips
- Reset the oven by turning off the gas supply and waiting a few minutes before turning it back on.
- Clean the oven thoroughly, including the burners and the interior.
- Check the oven’s user manual for specific troubleshooting instructions.
