Stove Repair in Lower Merion & Narberth

A gas burner needs three things at the same moment: gas from the valve, air mixed in at the right ratio, and a spark or flame to light it. Turning a knob opens a valve to that burner and closes a small switch that signals the spark module, and the module then pulses every igniter on the stove together. That shared circuit explains why turning one knob sets off clicking under every burner. Gas flows through a small orifice, mixes with air in the burner base, and comes out under the cap through a ring of ports, where the spark lights it.

That chain gives a few predictable failure points. The igniter can be wet, dirty or cracked. The burner cap can sit crooked after cleaning, or the ports can be clogged with boil-overs. The spark switch behind the knob can get wet and click nonstop. And, less often, the valve itself can stick or leak internally.
