About LG Cooktop Repair
LG relies on its linear/direct-drive inverter compressors and motors (marketed for quiet operation and fewer moving parts) and ThinQ smart connectivity across its lineup. Known for InstaView door-in-door refrigerators and TrueSteam laundry technology. That means LG isn't a typical cooktop manufacturer, but if you have a LG-branded unit in this category, our technicians still apply the standard approach: diagnosing burner ignition or induction coil faults, control board and touch-panel issues, and element/surface heating problems behind uneven heat or no-power complaints, sourcing OEM-compatible parts where the original brand's parts aren't available.
Ready to Fix Your LG Appliance
We service the full range of LG appliances found throughout Houston-area homes, including refrigerator, washer, dryer, dishwasher, oven, freezer, cooktop, stove, range, and microwave, and every one of those categories gets the same certified diagnostic attention regardless of which specific unit is giving a household trouble. We treat every LG appliance throughout our coverage area with that same level of certified care, regardless of a household's specific neighborhood or property type.
We keep emergency scheduling flexible for LG appliance failures throughout our coverage area, understanding how directly a broken refrigerator or washer disrupts a household's daily routine.
That commitment to honest, certified LG service is exactly what we intend to keep bringing to households throughout greater Houston, without exception, for many years to come.
A genuinely large share of the LG calls we handle throughout our coverage area involve a unit that's still well within its useful life but has developed a single specific fault, and we consider correctly diagnosing and fixing that one component, rather than recommending a wholesale replacement, part of doing this job honestly.

Cooktop Problems We Fix on LG Models
Burner Not Working
A single burner that won't ignite or heat is one of the most common cooktop repairs.
Usual causes: Clogged igniter port (gas), Failed spark module (gas), Worn surface element switch (electric), Burned-out coil element (electric).
Won't Ignite
A gas burner that clicks but won't light requires immediate attention.
Usual causes: Clogged burner ports, Wet or cracked ceramic igniter, Faulty spark module, Faulty gas valve.
Constant Clicking When Not in Use
The gas cooktop produces constant clicking sounds even when all burners are off and no knob is turned.
Usual causes: Moisture in the igniter module from spill or cleaning, Food debris shorting an igniter switch contact, Failed igniter switch conducting continuously, Shorted igniter wire touching chassis.
Burner Knob Broken or Missing
A control knob for a gas or electric burner is cracked, broken, or missing.
Usual causes: Physical impact or forcing knob against incorrect position, Plastic fatigue from heat cycling near burner, Knob accidentally broken during cleaning, Child pulling on knob.
Spark Igniter Electrode Failed
The spark electrode for one or more burners is cracked, broken, or no longer producing a spark.
Usual causes: Electrode cracked from heat cycling, Physical impact during cleaning, Food boilover causing thermal shock to electrode ceramic, Electrode tip worn from extended use.
Cooktop Requiring Specific Cookware
The cooktop is only working properly with certain types of cookware and not with others.
Usual causes: Induction cooktop requires ferromagnetic cookware — this is by design, Smooth-top works best with flat-bottomed cookware — warped pans cause poor contact, Gas cooktop grates designed for specific size cookware, Cooktop surface damage causing poor contact with some pan types.
Downdraft Vent Not Working
The pop-up or built-in downdraft ventilation on a cooktop is not operating.
Usual causes: Downdraft motor failed, Duct below cooktop blocked or disconnected, Control switch for downdraft failed, Lift mechanism for pop-up downdraft seized.
Surface Element Only Works at Full Power
The electric cooktop element is stuck at full heat regardless of the setting selected.
Usual causes: Infinite switch welded in the on position, Wiring fault bypassing the switch, Knob not engaging the switch correctly — stuck at full, Control board relay welded on (electronic models).
Radiant Element Cracked or Burned
A smooth-top radiant element has a visible crack or burn mark visible through the glass ceramic surface.
Usual causes: Element coil burned through creating a visible hot spot, Arc to the glass surface from a failed coil, Physical impact cracking the glass at the element location, Overheating from warped cookware concentrating heat at one point.
Surface Element Heating Intermittently
An electric cooktop element works sometimes but randomly stops heating mid-cooking.
Usual causes: Infinite switch making intermittent contact, Element terminal connection intermittently loose, Element itself failing — hairline break in coil conducting sometimes, Control board relay intermittent (electronic models).
Cooktop Surface Permanently Stained
The glass ceramic cooktop has a permanent discoloration that cannot be removed with normal cleaners.
Usual causes: Aluminum or copper cookware depositing metallic oxide on hot surface that fused, Sugar boilover at very high temperature permanently bonded to glass ceramic, Incorrect cleaning chemicals that reacted with the glass surface, Old burn that was not cleaned promptly and now bonded to the surface.
Electric Cooktop on Wrong Voltage
The cooktop is not heating properly and may be connected to an incorrect voltage supply.
Usual causes: 220V cooktop connected to 110V circuit — will underperform significantly, Only one leg of 240V circuit working — acts like 120V, Circuit breaker for one 240V leg tripped leaving partial power, Wrong wire gauge for the cooktop's amperage causing voltage drop under load.
