Possible Causes
How to Fix / Troubleshooting
Safety first: Turn off power to the cooktop and close the gas supply valve. Continuous sparking can ignite gas if there is a leak.
- Dry the control area: Remove the knobs and wipe away any moisture. Allow the area to dry fully; use a hair dryer on low if needed.
- Inspect switches: With power disconnected, check each valve shaft for free movement. If a switch is visibly damaged or corroded, it must be replaced.
- Test operation: Restore power and check if sparking stops when all knobs are OFF.
When to call a technician: If F1 remains or sparking continues, a spark switch or ignition module is likely shorted and should be replaced by a professional.
