4 Pack - XPARTCO EXP480 Microwave Door Switch — SPDT Normally Closed / Normally Open
3-terminal microwave door-interlock micro switch with Common, Normally Closed (NC), and Normally Open (NO) contacts.
Product Overview
The XPARTCO EXP480 Microwave Door Switch is a three-terminal SPDT micro switch used in compatible microwave door-interlock systems. Its three terminals provide Common (COM), Normally Closed (NC), and Normally Open (NO) contacts.
This is a quality XPARTCO aftermarket replacement part. It is rated for up to 16A and 250VAC and uses approximately 6.3 mm (1/4-inch) quick-connect terminals.
Quick Answer
EXP480 is a 3-terminal SPDT microwave door switch with both NC and NO contacts. It is not the same as a 2-terminal NC-only or NO-only switch. Match the original switch part number, terminal count, contact arrangement, actuator position, and mounting geometry before ordering.
Common Problems This Part May Fix
- Microwave will not start when the door is closed
- Microwave stops when the door is moved or pressed
- Interior light or fan behaves incorrectly with the door open/closed
- Door-interlock switch has intermittent continuity
- Original switch terminals are burned, loose, or damaged
- Microwave displays door-related symptoms caused by a failed interlock switch
Replaces and Cross-References
Cross-reference numbers may span different production revisions. Always compare the original switch's terminal arrangement, actuator, mounting points, and appliance model before installation.
Compatibility
Used in select microwave door-interlock systems from Whirlpool-built brands including Whirlpool, KitchenAid, Maytag, JennAir, Amana, Estate, IKEA, Kenmore, and related models.
Important: Microwaves can use more than one door switch in the same latch assembly, and those switches may have different contact logic. Do not substitute this SPDT NC/NO switch for a 2-terminal NC-only or NO-only switch unless the appliance documentation specifically calls for the same configuration.

Microwave Safety & Installation Notes
Microwave ovens contain high-voltage components that can retain a dangerous or fatal electrical charge even after the unit is unplugged. Door-interlock switches are safety-critical components.
- Do not bypass or defeat any microwave door-interlock switch.
- Do not guess between NC, NO, and SPDT switch types.
- Disconnect power and follow the manufacturer's service procedure.
- After replacement, the microwave's shielding and door-interlock system must be properly tested before the appliance is returned to service.
- Professional microwave service is strongly recommended.
Frequently Asked Questions
Is EXP480 normally open or normally closed?
Both. EXP480 is an SPDT switch with one Common terminal, one Normally Closed terminal, and one Normally Open terminal.
Is this the same as EXP497 or XPG499?
No. Those listings use different contact configurations. Match the exact switch type required by your appliance.
Does this replace W10211972?
Yes, EXP480 is cross-referenced to W10211972 and its related superseded numbers, subject to exact appliance fitment and switch configuration.
Can I bypass the switch to test the microwave?
No. The door-interlock system is a critical microwave safety system and should never be bypassed.
Shop With Confidence
Verify the complete microwave model number and original switch configuration before ordering. The terminal count and NC/NO logic must match the original application.
