LG Range Oven relay control board EBR52349704, Replaces EBR52349702

LG relay PCB/power-control board for a range oven. It receives signals from the main control board and operates relays that regulate the oven elements.

Is This the Right Part?

Common Symptoms

• Bake or broil heating may not operate when commanded.
• Oven may overheat or continue heating if a relay contacts remain closed.
• A relay-related fault condition may occur, including an oven-too-hot condition on applicable LG models.
• The oven light or other electrically supplied oven function may lose power if the board’s power-supply circuitry fails.

Check Before Replacing

• Disconnect electrical power to the range before accessing or testing the board.
• With power disconnected, inspect the board, relay area, connectors, and wiring for visible burning, loose connections, or damage.
• For applicable LG service procedures, test the relevant heater-relay-to-line resistance with power off: infinite resistance is identified as normal, while continuity is identified as abnormal.
• Verify the appliance model and board markings before replacement; do not condemn the relay board solely from a no-heat symptom because wiring, the heating component, sensor, or main control can produce similar symptoms.
