LG Oven Broiler Not Working — What’s Happening
When the broiler is not working in your LG electric oven, the control is calling for broil heat but the broil element is not getting hot or glowing red. This means the broil circuit is either open somewhere or not receiving the voltage it needs to energize the element.
In practical terms, you select the broil function and wait, but the element stays cold and your food does not cook. LG’s own troubleshooting guidance for oven heating issues points first to power resets, cycle selection checks, and door gasket inspection before moving to component-level service.
Most Likely Causes
- Burned-out broil element The broil element itself has failed, often showing visible breaks, blistering, or simply no red glow when power is applied.
- Loose or burnt wiring at the broil element The wires and connectors near the broil element overheat or corrode because they sit close to the heat source, interrupting the power supply.
- Defective electronic control board The control board is not sending voltage to the broil element even when the broil cycle is selected.
- Faulty temperature control thermostat On models with thermostat-based regulation, a defective thermostat can interrupt the broil circuit.
- Tripped breaker or power interruption A partial power loss or tripped circuit breaker can leave the control functioning but cut voltage to the element.
- Compromised door gasket or calibration drift LG notes that broader heating-performance issues can relate to calibration, convection settings, or a damaged door seal allowing heat loss.
How to Diagnose and Fix
- Verify the oven has full power and reset the breaker for 30 seconds, then retry the broil cycle.
- Confirm you have selected the correct broil mode on the control panel and check whether any error code is displayed.
- Turn off power at the breaker and observe the broil element during a broil call to see if it glows red.
- If the element does not heat, inspect it for visible breaks, blistering, or burn marks.
- Disconnect power, remove the broil element, and test it with a multimeter for continuity across its terminals.
- Inspect the broil element wiring and terminal connectors for burnt insulation, loose connections, or heat damage, and repair or replace damaged wire or connectors.
- If the element and wiring test good, inspect the electronic control board for burn marks or shorted components and verify whether it is sending line voltage to the broil circuit.
- If your model uses a temperature control thermostat in the broil path and all other components are intact, test and replace the thermostat if defective.

When to Call a Pro
If you are not comfortable working inside a 240-volt appliance, call a technician before opening any panels. If you have tested the broil element for continuity, inspected all visible wiring, and the problem persists, the control board or internal thermostat is the likely culprit and professional diagnosis with a schematic and voltage meter is the next step. LG recommends service if basic troubleshooting does not resolve heating performance issues. For gas line, burner, or igniter work, or if you ever smell gas, stop and call a licensed technician.
