Whirlpool Gas Range Spark Switch (12002790)

The Whirlpool Gas Range Spark Switch is the control component that sends an electrical signal to the igniter when you turn a burner knob, triggering the spark that lights the gas. It works by completing a circuit each time the knob is rotated to the ignite position, activating the spark module and producing the clicking sound that ignites the burner flame.

The Whirlpool Gas Range Spark Switch can fail from grease and food spills that seep into the switch mechanism, normal contact wear over time, or moisture damage from boilovers. A faulty switch may cause constant clicking when no burner is in use, or prevent a burner from sparking at all when you need it to light.

These symptoms can help you decide if the spark switch matches your problem:

- One or more burners will not spark or ignite when the knob is turned

- Clicking sound continues non-stop even when all burners are off

- Burner only sparks intermittently and does not light reliably

- Spark works on some burners but not the one tied to the faulty switch

- Visible corrosion, cracking, or grease buildup on the switch contacts

- Burner requires multiple attempts to ignite each time it is used
