Possible Causes
Weak hot surface igniter, Faulty gas safety valve, Loose igniter wiring, Incorrect line gas pressure
How to Fix / Troubleshooting
Safety first: Turn off gas and power before servicing. Gas work should be done by qualified personnel.
- Measure igniter current: A weak igniter may glow but not draw enough current to open the gas valve. Test current draw against Bosch specifications.
- Inspect igniter: Look for cracks or white spots on the igniter. Replace if damaged or if current is low.
- Check wiring: Ensure igniter leads are securely connected and not heat-damaged.
- Gas valve: If a new igniter does not resolve the issue, the gas valve may be faulty and should be replaced by a professional.
