How to Fix / Troubleshooting
Critical safety warning: Gas-related work must comply with local codes. If you smell gas, shut off the gas supply, ventilate the area, and contact a professional immediately. Do not attempt repairs if you are not qualified.
Steps:
- 1. Check gas supply: Ensure the gas valve to the heater is open and other gas appliances are working.
- 2. Inspect igniter and flame sensor: With power and gas OFF, remove the burner access panel. Clean the igniter and flame sensor rods with fine emery cloth to remove soot.
- 3. Check electrode gap: Verify the igniter gap and position relative to the burner per Electrolux specifications.
- 4. Clean burner: Remove and clean the burner and orifices to ensure proper gas flow.
- 5. Test ignition: Restore gas and power, then attempt to start the unit while observing through the inspection window. If no ignition or flame sensing occurs, the gas valve or control board may be faulty.
Professional help: Gas valve and combustion control diagnostics must be performed by a licensed gas technician.
