How to Fix / Troubleshooting
Safety: Turn off gas and power. Do not attempt to open or repair the gas valve body.
- Check wiring: Locate the gas valve on the Beretta furnace gas train. Inspect the electrical connector and wires for damage or loose terminals. Reseat the connector firmly.
- Inspect for overheating: If the gas valve coil area is discolored or smells burnt, the valve may be failing and must be replaced.
- Reset and test: Restore power and gas, reset the fault, and observe operation. If A09 returns, the gas valve or control board is likely defective.
Gas valve replacement and gas tightness testing must be performed by a licensed gas technician.
