How to Fix / Troubleshooting

Safety first: Disconnect the appliance from mains power before accessing controls.

Dry the area: If the issue started after a spill or cleaning, allow the cooktop to dry completely for several hours. You can gently blow warm (not hot) air around the knobs.
Identify faulty switch: Turn each knob one at a time. If clicking stops when a specific knob is moved or pressed, its switch may be stuck.
Access switches: Remove the cooktop surface to expose the ignition switches on the gas valves. Inspect for moisture or corrosion.
Replace switch: If a switch is visibly damaged or tests shorted with a multimeter, replace that ignition switch.
Check wiring: Inspect ignition wiring for insulation damage that could cause a short to chassis.

Gas cooktop ignites but keeps clicking even after the flame is established.
