Rangetop and cooktop repair

A rangetop is a cooking surface with no oven under it, dropped into a counter with cabinetry below. A cooktop is shallower still. Both bring problems a freestanding range never has, because both live inside somebody else’s carpentry.

Gas surfaces

The burner faults are the same as on a range: fouled igniter tips, blocked ports, a spark module that has taken moisture, a burner cap sitting proud of its seat. What differs is access. On a rangetop the whole assembly sits in a cutout with a cabinet below, and the amount of room behind the unit decides how much can be done without pulling it. In a kitchen where the opening was cut to the old appliance rather than the new one, that margin can be nothing at all.

Griddles and French tops are their own diagnosis. A griddle plate that heats unevenly is usually not a burner fault — it is a plate that has warped away from its heat source, or a thermostat bulb that has lost contact with the underside. The test is a temperature map across the plate at steady state, not a single reading in the middle.

Induction surfaces

Induction fails in ways that look like magic and are not.

An element that drops out under load is usually thermal. The coil sits above a cooling fan and a heatsink, and if that fan is choked with dust or its intake under the counter is blocked by cabinetry, the electronics protect themselves by backing off power. The symptom is a hob that works beautifully for ten minutes and then goes quiet. Nine times out of ten the fix is airflow, not a board.

Pans matter more than owners expect. A pan with a warped base makes intermittent contact, and the surface reads intermittent contact as no pan. A pan smaller than the element’s minimum detection diameter will not start at all. Before we condemn a coil we test with a known-good flat ferrous pan.

Touch controls that respond at one end of the panel and not the other are a ribbon or a control board issue, and heat is nearly always the reason. A control board that lives directly beneath a hot surface ages by degree-hours, not years.

Electric radiant

Radiant elements cycle. They are meant to. When the cycling gets noticeably faster or the element glows unevenly, the infinite switch or the element itself has drifted. Both are straightforward to test with a meter and both are straightforward to replace.

The retrofit problem, locally

A large share of the coastal kitchens here are second- or third-generation renovations built around an original cabinet opening. When a wider or deeper unit goes into an older cutout, you get one of three outcomes: reduced clearance to combustible material at the sides, a rear gap that will not take the gas connection without a hard bend, or a unit that sits on its trim rather than on its support. All three shorten the life of what is in the hole, and the last one cracks glass.

We measure the opening before we quote a replacement part that depends on it.

What a visit looks like

Flat diagnostic fee, credited toward the repair when you go ahead. Written estimate before anything is ordered, genuine OEM parts, and if the fault is a clearance or supply problem rather than a component, we say so and you keep the part money.
