Range and Cooktop Repair
The surface side of a professional range: sealed burners, spark modules, gas valves and the simmer settings that stop behaving long before anything fails outright.
How it gets described on the phone
- One burner clicking over and over while the rest light on the first turn
- Flame that lifts away from the port and snuffs itself out when the hood goes to full
- Simmer that either drops out completely or runs hot enough to catch a sauce
- Knob that turns through its travel with no click and no gas behind it
What gets tested on the visit
- Supply pressure read at the regulator with a manometer, then again at the burner under load
- Burner caps and heads lifted, ports cleared and each cap checked for a flat seat on the head
- Spark module and each electrode tested individually — a module that fires all burners at once is its own fault
- Valve travel and the simmer stop through the full sweep of the knob, not just at full input
- Flame shape read cold and again after ten minutes with the extraction on high
The first split on a surface call is fuel against spark. A burner that clicks is telling you the ignition side is alive, which puts the fault in the cap, the port, the orifice or the valve. A burner that neither clicks nor lights puts it in the switch, the module or the harness. That one distinction decides which half of the appliance comes apart, and it costs nothing to make.
