A rangetop sits in the counter with no oven underneath it, which changes what can go wrong and where we have to get to. The gas train, the valves and the spark system all live in a shallow chassis under the cooking surface, and on a drop-in installation the access route is from above, through the burner wells, or from below through the cabinet. ## Clicking that will not stop A burner that keeps sparking after it has lit is telling you that the module never received confirmation that a flame exists, or that a switch never opened. The two common physical causes are a wet or soiled electrode and a burner cap sitting a fraction out of position. Cooktops get washed. Caps get lifted off, cleaned, and put back down rotated slightly or resting on a crumb. The slot that indexes the cap to the burner head exists precisely so the flame lands where the electrode expects it, and a cap that is a few degrees out will click forever without ever satisfying the module. We seat every cap, check the electrode gap and its ceramic for cracks, and dry anything that is wet before a part is named. If all positions spark when one knob is turned, the fault is at the module or in a switch that is stuck closed, and that is a different repair. ## Yellow flame and lazy flame A clean burner burns blue with a defined cone. Yellow, tipping flame means the air-to-gas mixture is wrong: ports partially blocked, the air shutter disturbed, or the appliance running on the wrong fuel setting. Liquid propane conversions are the usual culprit behind the last one. A conversion is three separate steps — orifices, regulator, and the low-flame adjustment at each valve — and a range converted quickly usually has one of them outstanding. It shows at simmer first, because simmer has the least margin. ## Stiff knobs Valve stems turn against a high-temperature grease packed in at assembly. Over years of heat that grease migrates and hardens, and the knob gets stiff, gritty, or refuses the last few degrees into the low position. Forcing a stiff valve is how stems snap. The correct repair is to service or replace the valve, and on a rangetop that means getting into the manifold, which is why we would rather do it at the first sign of stiffness than after the stem has broken off in the knob. ## Griddles and grill sections An integrated griddle heats through a plate with a thermostat sensing its underside. Uneven heating is usually the plate itself — warped from a cold liquid hitting it hot — or a thermostat sensing at a spot that no longer contacts the plate properly. Neither is diagnosed from the top; the plate has to come up. ## Induction surface elements An induction element that cycles rapidly at a low setting is usually behaving correctly: at low power the coil pulses rather than modulating continuously, and you hear it as clicking or as the cookware humming. What is not normal is an element that shuts down after a few minutes at a high setting, which points at the cooling fan, a blocked air path under the unit, or a temperature sensor under the glass. Induction also depends heavily on the pan. A pan with a slightly domed base or a thin disc bottom will heat poorly and get blamed on the appliance. We check with a known-flat ferrous pan before going further. ## What we check before any of it The gas supply and the electrical supply. A rangetop needs 120 volts for its spark and controls even though it cooks with gas, and a cooktop that has been sharing a general-purpose circuit in an older Mandarin kitchen will misbehave in ways that look like component failure.

Call (904) 822-9883 Owner feedback ## What owners said after a rangetops visit 4.3 out of 5, across 33 customer reviews. Each one below is a single visit, in the words of the person who paid for it. Read all 33 of them ★★★★★ Our griddle ran hot at one end and cool at the other, so nothing on it cooked evenly. One of its two elements had gone open, and that was what he replaced. Both ends match now, which they had not for a year. Curtis B.2026-07-02 ★★★★☆ A gas smell near the back of the rangetop worried us. He leak tested every joint with solution, found a loose flare fitting behind the unit, tightened it and retested. Nothing since, and he said what to watch for. Janelle S.2026-01-30 ★★★★★ The simmer plate had warped and one burner roared no matter how low we set the knob. He replaced the burner cap and the valve under it, then set the low flame with the kitchen door shut so it stayed steady.
