Cooktop Repair
Sealed burners, spark modules, valves and orifices — the ignition and flame-quality work that starts at the burner head and ends at the gas valve, plus the flat-top and griddle surfaces beside them.
How it gets described on the phone
- Flame lifting off the burner head or burning yellow instead of blue
- Burner that lights but will not hold a low simmer without going out
- Knob that has become stiff, gritty or will not return cleanly to off
- Spark that continues after ignition, or several burners sparking together
What gets tested on the visit
- Burner heads and caps lifted and the ports checked for blockage and spill damage
- Electrode gap and ceramic condition inspected on every burner, not only the one that failed
- Spark module behaviour watched during and after ignition
- Valve action through its travel, and the stop the knob returns to
- Flame shape and colour at high and at simmer, then a leak test on anything opened
Most cooktop calls come down to something that got wet or something that got blocked. A spill under a cap will stop a burner lighting from its own spark while a match lights it instantly, and that one distinction — match yes, spark no — already tells you the gas side is fine and the problem is ignition. Yellow, lifting or roaring flames are a different family: air shutter, orifice or pressure, and they are the ones worth measuring rather than adjusting by eye.
