Cooktop infinite switch repair is about the part that turns a knob position into a level of heat. An infinite switch holds a small bimetal strip that clicks the element on and off in a timed cycle; the lower the setting, the shorter the on time. After years of cycling the contacts pit or weld, and the zone then heats only at full power, stays cold until high, or keeps heating after the knob reaches off. The same repair covers knobs that slip on a worn shaft, cracked knob inserts and the indicator light wiring that shares the switch. On gas cooktops and rangetops, knobs that no longer grip their valve stems are replaced here too; the valves themselves are a separate job. How the visit goes ### What it usually costs Low · Infinite switch or knob A knob is minor, and a switch is a short job reached through the lifted top or the front panel. Burnt terminals on the switch are renewed during the same visit. ### Answers 5 problems Cooktop Element Only Heats on High Cooktop Simmer Too Hot · Cooktop Burner or Element Won't Turn Off · Cooktop Element Not Heating · Cooktop Hot Surface Light Stays On ### Comes up most on Electric cooktop Gas cooktop · Rangetop ## Infinite switch and knob repair, step by step.

Is the switch failing? No, that is the switch doing its job. At every setting below high it switches power on and off in a timed cycle, and on a radiant zone you can see the glow come and go. Only a zone that never cycles, or cycles on high, points at the switch. ### The knob spins but nothing happens. Is it the knob or the switch? If the knob turns with no resistance, the flat inside it has worn round, and a new knob fixes it. If the knob grips and the zone still stays cold, the switch or the element is next. ### Can one bad switch damage the rest of the cooktop? A switch with welded contacts keeps an element at full heat and can overheat the wiring and terminals nearby. Switch that cooktop off at the breaker until it is repaired. ### Can I change my cooktop knobs to a different style? Only knobs made for the same shaft fit securely. A universal knob that sits loose or off angle can show the wrong setting, which matters on something that cooks, so matched parts are used. --- **[Read on the site: Cooktop Infinite Switch and Knob Repair](https://cooktoprepair.center/services/infinite-switch-and-knob-repair/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
