LG Microwave Oven Spring

Maintain effortless door latch operation and daily kitchen convenience with the authentic LG Microwave Door Release Button Spring (Part No: 4B72023B). Functioning as the primary tactile return mechanism inside the control panel assembly of compatible LG microwaves, this genuine OEM spring applies constant outward pressure to the push-button lever mechanism.

Whether your microwave push button stays stuck inward after press, feels loose and unresponsive, or fails to trigger the internal door latch levers, replacing a worn or snapped spring restores original push-button action and clean door release.

Key Features

• 100% Genuine LG Component: Designed directly to original equipment specifications for precise tension, coil diameter, and seated height.

• High-Tensile Helical Steel Construction: Built from resilient spring steel to withstand continuous mechanical compression without losing elasticity.

• Smooth Button Reset: Delivers immediate tactile feedback, resetting the door push-button back to its rest position instantly upon release.

• Corrosion-Resistant Coating: Treated to endure normal kitchen humidity and temperature fluctuations inside the control console.

Benefits

• Fixes Stuck Door Release Buttons: Resolves issues where the release button remains depressed or fails to pop back out.

• Restores Smooth Latch Disengagement: Ensures the internal latch actuator disengages cleanly to allow smooth door opening.

• Low-Cost Targeted Repair: Fixes push-button return mechanical failure without replacing the entire control panel assembly or outer door frame.

Applications

• Returning the push-button mechanism on compatible LG countertop and over-the-range (OTR) microwaves.

• Replacing lost, rusted, stretched, or broken release button compression springs during appliance maintenance.
