Urgency: High

Important Tips for Lg Models

LG oven broiler/heating issues often loose or burnt wire connections to heating elements as a primary fault before other components.

Possible Causes

Loose or poorly connected high-current wiring near heating elements

How to Identify: Visible charring, discoloration, or burnt insulation on wires near element terminals or harness; may smell burnt

Part: Internal wiring harness to heating element/igniter

Overheating due to inadequate high-temperature rated wiring or insulation degradation

How to Identify: Wires with damaged insulation away from terminals, brittle insulation, signs of heat stress consistent with high-temperature exposure

Part: High-temp rated oven wiring insulation

Short circuit or arcing due to exposed conductors

How to Identify: Sparking/arcing during operation, breaker trips, burnt contact points, black soot near connections

Part: Exposed internal wiring/terminal connections

DIY Solutions

Visual Inspection and Tightening of Accessible Screw-Terminal Connections

Moderate 15â€“30 minutes

Tools Needed: screwdriver set, flashlight

Disconnect oven from all power (unplug or trip breaker).
Access the area near heating elements or igniter and visually inspect wiring terminals.
Tighten any loose ring or spade terminals carefully to manufacturer torque spec.
Replace any visibly charred wire portions with properly rated high-temperature wiring if replacement wire and crimps are available and safe.
Restore power and verify proper operation.

⚠️ Safety First: Always disconnect power before opening oven panels

Replace Short Section of Burnt Wire With High-Temperature Oven Wiring

Advanced 45â€“90 minutes

Tools Needed: high-temp rated wire, wire strippers, crimp tool, high-temp crimps, multimeter

Cut out the burnt section of wiring inside oven after ensuring power is off.
Strip ends and prepare new high-temperature rated oven wire of correct gauge.
Crimp high-temp connectors securely and insulate connections.
Check continuity with multimeter before restoring power.
Reassemble oven and test.

⚠️ Safety First: Must use appropriate gauge and temperature-rated wire
