Whirlpool Microwave Door Interlock Spring W10156812

OEM interlock spring used in the microwave door interlock mechanism. It provides tension that helps reset or position the interlock cam plate and supports proper door latching and operation.

Is This the Right Part?

Common Symptoms

• Door does not latch or release normally.
• Microwave does not start because the door-interlock mechanism may not engage.
• Door-interlock switch engagement is inconsistent.
• The spring is visibly stretched, deformed, detached, or broken.

Check Before Replacing

• Unplug the microwave before inspection; do not open or service the high-voltage section.
• With power disconnected, visually inspect the spring, cam plate, and interlock support for detachment, distortion, or breakage.
• Operate the door gently and observe whether the cam plate returns to its normal position after the door is opened.
• Confirm that the spring ends remain seated in the cam plate and interlock support; do not force the door or bypass the interlock system.
• If the mechanism appears intact but the microwave still has a door or start problem, have the interlock switches and related components tested by a qualified technician.

Pro Tip

Part Details

Key Features

• Genuine Whirlpool OEM interlock spring.
• Used in the microwave door-safety/interlock mechanism.
• Provides return tension for the interlock cam plate.
• Small spring-steel component intended for repeated door-cycling operation.

Installation Notes

• Disconnect electrical power before beginning any inspection or repair.
• The replacement procedure requires restoring the spring in the same orientation: the L-shaped end engages the cam plate and the hooked end engages the support.
• Do not bypass, defeat, or modify the microwave door-interlock system.
• Because microwave high-voltage capacitors can retain a lethal charge even when unplugged, internal installation should be performed by a qualified service technician unless the applicable service documentation and safety procedures are followed.
