XPARTCO XPG499 Microwave Door Switch — Normally Closed (NC)
Two-terminal microwave door-interlock micro switch rated 16A at 125/250VAC for compatible microwave ovens.
Product Overview
The XPARTCO XPG499 Microwave Door Switch is a normally closed (NC) micro switch used in the microwave door-interlock system. The switch changes state when the door-latch mechanism actuates it, helping the microwave control system verify door position.
This is a quality XPARTCO aftermarket replacement part designed to replace many common two-terminal normally closed microwave interlock switches.
Quick Answer
XPG499 is a normally closed, two-terminal microwave door switch rated 16A at 125/250VAC. It cross-references to common switch families such as WB24X830, WB24X800, W10269458, 8206347, 6600W1K001C, 3405-001033, and related numbers. Match the original switch's electrical function, terminal layout, actuator style, mounting dimensions, and appliance model before installation.
Common Problems This Part May Fix
- Microwave will not start when the door is closed
- Microwave stops when the door or latch is moved
- Door-latch mechanism does not actuate the interlock switch correctly
- Intermittent operation caused by a worn or failed micro switch
- Continuity test shows the original NC switch is not operating correctly

Microwave Safety & Installation Notes
Microwave ovens contain high-voltage components that can retain a dangerous electrical charge even after the appliance is unplugged. Door-interlock switches are safety-critical components and improper installation or adjustment can create a hazardous condition.
- Disconnect power before service.
- Do not access high-voltage components unless trained and equipped to service microwave ovens.
- Confirm the replacement is the same switch function: Normally Closed (NC).
- Match the terminal arrangement, actuator position, and mounting dimensions to the original switch.
- Inspect the door latch, latch holder, switch bracket, and related interlock switches for damage or misalignment.
- After replacement, the complete microwave door-interlock system must be tested according to the manufacturer's service procedure before the microwave is returned to use.
Professional service recommended: GE specifically advises that microwave shielding and interlock switches be properly tested after door-interlock switch replacement.
