LG Cooktop Repair Cost in Newton, MA: Gas, Electric, and Induction
LG cooktop repair in Newton, MA usually costs $150 to $700. Gas burner igniters and spark switches are the most affordable common repairs. Radiant elements and control switches fall in the middle. Induction power boards and cracked glass tops are the most expensive, and glass replacement can exceed $800.
This guide covers built-in LG cooktops that sit in the countertop with no oven below. The cost depends on the cooktop type, the failed part, and how it's installed. Gas, radiant electric, and induction models fail in different ways, so a technician needs to confirm the cause before quoting. If your cooktop is the top of an LG range, see the LG oven and range repair cost guide instead.

Average LG Cooktop Repair Cost in Newton
Most LG cooktop repairs fall between $175 and $450. Gas cooktop igniter and switch repairs sit at the lower end of that range. Electric element and induction board repairs sit higher.
What changes the cost:
Cooktop type. Gas cooktops have igniters and valves. Radiant cooktops use heating elements and switches under glass. Induction cooktops use coils and power electronics.
Access. Built-in cooktops often need to be lifted out of the countertop to reach parts underneath.
Glass. Glass-ceramic tops are expensive to replace and must match the model.
Age. Older models may have limited parts, especially glass tops and induction boards.
Not sure what is causing the problem?
A dead burner or zone can come from a switch, element, coil, board, or power supply. Promix Appliance Repair can diagnose your LG cooktop and explain the repair options before work moves forward.
Common LG Cooktop Problems and Repair Costs
Problem | Likely Causes | Typical Cost |
|---|---|---|
Gas burner clicks but won't light | Igniter, burner cap, spark switch, spark module | $150-$300 |
Gas burner won't stop clicking | Wet spark switch, failed switch | $150-$275 |
Radiant element not heating | Element, infinite switch, board | $175-$400 |
Induction zone not working | Coil, power board, pan detection | $250-$700 |
Touch controls unresponsive | Touch panel, control board, lock | $250-$550 |
Cracked glass top | Impact, thermal stress | $400-$800+ |
Gas Burner Won't Light
The burner clicks but no flame appears. Causes include a wet or misaligned burner cap, a dirty or cracked igniter, or a weak spark module. Most repairs cost $150 to $300.
Gas Burner Keeps Clicking
Continuous clicking after the burner lights often follows a spill that soaked a spark switch. If the clicking continues after everything dries, the switch has likely failed. Replacement usually costs $150 to $275.
Radiant Electric Element Not Heating
One zone stays cold while others work. The element may have failed, or the infinite switch or control board may not be sending power. Element and switch repairs typically cost $175 to $400.
Element Stuck on High
An electric zone that gets very hot on every setting usually has a failed infinite switch or relay on the control board. Stop using that zone until it is repaired. Repairs usually cost $175 to $450.
Induction Zone Not Working
Induction cooktops only heat magnetic cookware. If a zone won't start, first test with a pan that a magnet sticks to. If the pan is fine, the cause may be a failed coil, power board, or sensor. Induction electronics are the costliest cooktop repairs, at $250 to $700.
Touch Controls Not Responding
LG cooktops with touch controls can stop responding because of control lock, spills on the panel, or a failed touch board. Board repairs typically cost $250 to $550.
Cracked Glass Cooktop
A crack can spread and may expose electrical parts. Stop using the cooktop and turn off the breaker. Glass replacement depends on part availability and often costs $400 to $800 or more.
LG Cooktop Repair Cost by Part
Component | Typical Repair / Replacement Cost |
|---|---|
Burner igniter | $150-$275 |
Spark switch / spark module | $150-$300 |
Radiant surface element | $175-$375 |
Infinite switch | $175-$325 |
Touch panel / control board | $250-$550 |
Induction coil | $250-$500 |
Induction power board | $350-$700 |
Glass cooktop | $400-$800+ |
LG Cooktop Error Codes
LG induction and electric cooktops can display codes for overheating, sensor faults, and pan detection problems. Meanings vary by model, so check your owner's manual first. A code that returns after turning the breaker off and on usually means the cooktop needs service.
What Makes LG Cooktop Repair More Expensive?
Built-in cooktops have to be lifted from the countertop, which takes care with stone surfaces. Induction power electronics cost more than gas or radiant parts. Glass tops are model-specific and can be hard to source for older units. A spill that reaches the electronics can damage several parts at once.
Can You Check Anything Yourself?
Check the breaker. Electric and induction cooktops often use a double breaker.
Turn off control lock.
Dry and reseat gas burner caps after cleaning.
Test induction zones with cookware a magnet sticks to.
Wipe spills off touch controls and let them dry.
If you smell gas, do not light anything. Leave the home and call your gas utility from outside. Never use a cracked glass cooktop or work on wiring underneath.
Is It Worth Repairing an LG Cooktop?
Igniters, switches, elements, and many touch panel repairs are worth doing on a cooktop in good condition. Built-in cooktops fit a specific countertop cutout, so a replacement may require a model with exactly the same dimensions.
Cracked glass and induction power board failures on older cooktops deserve a closer look. Compare the repair estimate with the cost of a new cooktop that fits your cutout, and consider age, previous repairs, and parts availability.
Before replacing your LG cooktop, consider having the actual failure diagnosed.
A switch, element, or igniter may be the only problem. Promix Appliance Repair serves homeowners in Newton and can help identify the failure.
