LG Microwave Oven Lever

The LG Microwave Door Interlock Actuator Lever (Part Number: 4510W4A005A) is an authentic original equipment manufacturer (OEM) replacement component designed for LG microwave ovens and range-oven models. Positioned behind the control panel inside the latch board assembly, this pivoted mechanical lever transfers motion from the door key hooks to depress internal microswitches, confirming to the main control board that the door is securely closed before allowing heating to begin.

Key Features

• Genuine OEM Precision: Engineered directly by LG to ensure precise pivot alignment, smooth mechanical leverage, and reliable microswitch actuation.

• Durable Molded Polymer: Constructed from high-grade, heat-resistant plastic designed to withstand repeated door opening and closing impacts without cracking or deforming.

• Integrated Pivot Mount: Features a molded cylindrical hinge pivot point for smooth rotational movement within the latch bracket frame.

Benefits

• Solves door interlock failures, such as microwave blowing fuses when the door opens, failing to start, or displaying door error codes.

• Replaces cracked, worn, or broken levers that fail to depress safety microswitches properly.

• Restores essential factory safety mechanisms to prevent microwave operation when the door is open.
