Local conditions
Symptom, local cause, and how we test — each card stays short for mobile scanning.
A LG range burner stuck on high in Sandpiper Bay is isolated at the breaker the same visit — welded infinite-switch contacts, not a new cooktop.
Port St. Lucie 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 along Becker Road and Prima Vista Boulevard 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.
Enter the meter reading
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
Port St. Lucie jobs are shop-adjacent. We treat canal-side condensers and Becker-corridor surge boards as the default, not a generic 'Florida humidity' note. Water here is the city blend: scale shows up late, ice rooms freeze from moisture, and gated St. Lucie West stops need the village name before the van rolls. For LG ranges here: Water is not the story — welded infinite switches and RTD drift are. Dishwasher and washer heaters in 1990s–2000s homes; ice-maker valves last longer here and then fail from humidity freeze-ups rather than calcium alone. Access: Put the village name and the preferred gate on the ticket. Daytime radar pockets run Village Parkway, Crosstown, River Park / White City, then Sandpiper Bay — we do not bounce I-95 twice in one window.

First meter check: 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'). Stuck-on-high is a same-visit safety job: We kill power at the breaker, pull the switch, and will not leave a welded infinite switch 'to watch.'

Triage on this platform (10–15 years): repair when 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.
