How much does a cooktop infinite switch replacement cost?#
A cooktop infinite switch costs $100 to $190 to replace, typically about $145. The control that sets how much power a burner draws is an inexpensive part, so the labor to reach it behind the front panel is the larger share of the bill. That leaves the job far below the $400 to $2,000 a new surface costs installed, so an element you cannot turn down is a small repair rather than a reason to replace the whole cooktop.
What the burner does tells you which part failed#
The infinite switch and the element under one zone fail into overlapping symptoms, and they are different parts at different prices. The distinction is in the pattern, not in the heat: a switch controls how long the element is on, so a switch fault is about timing, and an element fault is about heat itself.
| What that zone does | Which part | What it means |
|---|---|---|
| Full power at every setting, and the knob makes no difference | The infinite switch, welded closed | The repair this page prices — and worth acting on, because the zone has no low setting at all. |
| Cycles on and off far faster or slower than the others | The infinite switch, cycling out of calibration | The switch again. Compare against a neighbouring zone at the same setting; that is the test. |
| Never heats at all, on any setting | Either — an open switch or an open element | Needs a meter. Both are reached from the same place, so a technician settles it in one visit. |
| Heats, but never gets as hot as the matching zone beside it | Usually the element | Not a switch fault. A switch is a timer, not a dimmer. |
| Audible clicking from behind the knob while the zone is on | The infinite switch working normally | Not a fault. That click is the switch cycling, and every zone does it. |
| The knob turns loosely or spins without stopping | The switch shaft | The switch, mechanically this time. |
| Every zone dead at once | Neither. The supply or the main board | Nothing under one knob explains all four. Check the breaker first. |
| The indicator light stays on after the zone is turned off | The switch, not shutting cleanly | A switch fault with a safety edge — the surface may still be powered. |
Denominator: the $100 to $190 on this page is one figure for one job — a cooktop infinite switch, part plus the labour of reaching it behind the front panel — against $400 to $2,000 for a new cooktop installed. Two figures, not a survey across brands or regions, and neither covers the surface element itself, which is a separate part reached at the same time and priced on its own.
Cooktop infinite switch replacement cost
- What it does: the infinite switch sets how much power reaches an electric burner.
- Signs it is failing: a burner stuck on high, stuck on low, or that ignores the knob.
- The repair job: replacing the infinite switch and confirming the full heat range.
- DIY or pro: a moderate DIY job behind the control panel.
| What you pay for | Typical cost |
|---|---|
| Part plus basic labor | $100 |
| Typical repair | $145 |
| Premium part or hard access | $190 |
| A new cooktop, installed | $400–$2,000 |
Against a new cooktop at $400–$2,000 installed, a infinite switch repair at $100–$190 is usually the cheaper fix — unless the cooktop is already old or has other faults.
Pro note: a tech confirms the switch, not the element or a melted terminal, is what pins the burner to one heat setting.

Is replacing the infinite switch on a cooktop worth it?#
On any sound electric cooktop this is clearly worthwhile. The $100 to $190 outlay is trivial next to the $400 to $2,000 of a replacement, and a burner locked on full heat is genuinely unsafe to leave in daily use. Whether the element stays stuck on, dead, or refuses to vary between low and high, restoring proper control is the obvious move at nearly any age of appliance.
Cooktop Infinite switch replacement cost: FAQ#
How much does a cooktop infinite switch replacement cost?#
Expect $100 to $190, typically about $145. The control is cheap; the price mainly reflects opening up the panel area to reach it and testing the burner across its full range afterward.
Is replacing the infinite switch on a cooktop worth it?#
Yes. Against the $400 to $2,000 a new cooktop costs, the repair is easily justified, all the more so because a burner that will only run flat-out is a hazard you should not keep using.
What makes the infinite switch fail on a cooktop?#
Its internal contacts pit and wear from the heat and the constant on-off cycling that regulating a burner demands. The signs are an element stuck on high, stuck off, or with no usable middle range.
Can I replace a cooktop infinite switch myself?#
A handy owner can attempt it, but it means opening the control area and matching a part rated for that burner, and telling the control apart from a failed element takes testing — so many prefer to have it done.
How long does a cooktop infinite switch replacement take?#
Budget about 45 minutes: opening the control panel, swapping the part, and running the burner up and down its range to confirm smooth control has returned.
