How to Fix / Troubleshooting

Safety first: Disconnect power to stop the clicking. Turn off gas if you smell gas.

Steps:

Dry the cooktop: If a spill occurred, remove burner caps and knobs. Allow the area to dry completely. Use a hair dryer on low to gently dry around the switches.
Inspect switches: Under the top, locate the small microswitches attached to each gas valve. Check for signs of corrosion or physical damage.
Switch test: With power disconnected, use a multimeter to test each switch for proper open/closed operation when the knob is turned.
Replace faulty switch: Replace any switch that remains closed when the knob is off.
Ignition module: If all switches are good but clicking persists when powered, replace the ignition module.

Warning: Do not operate the cooktop with exposed live ignition wiring.

Gas cooktop shows Er03 and continuously clicks even when knobs are off
