Local conditions
Symptom, local cause, and how we test — each card stays short for mobile scanning.
A LG range burner stuck on high in Palm City proper is isolated at the breaker the same visit — welded infinite-switch contacts, not a new cooktop.
Palm City range cooktops are safety visits when a burner sticks on high. We isolate welded infinite-switch contacts, RTD ohms, and bake/broil relay logic the same visit.
Lightning on older rural services west of Martin Highway welds LG bake/broil relays and chatters infinite-switch contacts. A blank panel is a supply and breaker path first.
Common failures
Surface element / limiter
LG radiant cooktops drop a single burner when the limiter or element opens. Stuck-on-high is isolated immediately.
Spark module
All burners clicking with no flame is a module or ground path; one dead burner is usually the igniter or orifice, not the whole gas valve.
Cooktop control
Dual-fuel and slide-in LGs need independent cooktop and oven paths so a bake sensor is not blamed on a spark module.
Field diagnostics
Range calls split cooktop safety from oven temperature. A stuck-on burner is isolated before we talk about bake performance. Gas igniter current is measured, not guessed from glow color.
Platform: lg Cooktop infinite switch + oven cavity
| Component | Test | Spec / pass line |
|---|---|---|
| Infinite switch / IGBT on induction | Welded contacts or command voltage to the element | A burner stuck on high is a safety isolate first; welded contacts are a switch, not a 'hot element' |
| Surface element / gas igniter | Element ohms; igniter current on gas | Gas igniters that glow but will not open the valve are usually under ~3.2 A |
| RTD | Same platinum ~1090 Ω room-temp check as a wall oven | Drifted sensors cause overshoot that homeowners read as a runaway bake |
Interactive bench check
Ohm, kΩ, µF, or voltage — not an error-code lookup. Pick the component, enter what the meter shows, and we will tell you whether the control board is being lied to.
RTD / oven sensor. ~1080–1100 Ω at ~70°F on 1000 Ω platinum sensors (~1090 Ω typical)
Unplug or kill the breaker before opening the back panel. Do not ohm a live circuit.

Spec: ~1080–1100 Ω at ~70°F on 1000 Ω platinum sensors (~1090 Ω typical)
We kill power at the breaker, pull the switch, and will not leave a welded infinite switch 'to watch.'
Keep / repair: Cooktop glass or grate set is intact and the job is switch, igniter, or sensor
Replace when: Shattered glass-top, a rusted gas manifold, or stacked surface + oven control failures on an older dual-fuel
Hyper-local conditions
Palm City is well water and older electrical. Slow ice is an inlet screen until proven otherwise. Dead 240 V appliances get a panel check. Hidden Oaks and Citrus Boulevard are extended coverage — the ticket carries a window, not a 'be there in an hour' promise. For LG ranges here: Water is not the story — welded infinite switches and RTD drift are. Ice-maker fill valves clog with grit; washer screens load rust-tinged debris; dishwashers scale faster than any county-fed Stuart kitchen. Access: Share the cross street and whether the lot is well or county water. We confirm a defined arrival window so a western lot is not treated like Sandpiper Bay.
Private wells west of Martin Highway and toward Citrus Boulevard, plus some county-fed pockets closer to Stuart
Harder, iron-heavier, and dirtier than coastal Martin municipal water — this is sediment, not a light scale film
Ice-maker fill valves clog with grit; washer screens load rust-tinged debris; dishwashers scale faster than any county-fed Stuart kitchen
River-adjacent humidity on the east lots, inland heat on the acreage — milder salt than Jensen Beach
Older 100–200 A services on larger lots were not sized for today’s 240 V dryers and ranges
A 'dead' dryer or oven is a breaker or a loose lug as often as an internal part; door-boot mold still happens on the river side
