XPG497 Microwave Door Switch (Normally Open)
The XPG497 is an aftermarket normally open (NO) microwave door interlock switch, also designated EXP497, that restores proper start behavior so the microwave runs only when the door is fully closed. It is a replacement for many LG, GE, Whirlpool, Frigidaire, Kenmore, Samsung, Panasonic and Sharp door switches, including Frigidaire 5304509460. When the switch fails, the microwave may not start, may lose power intermittently, or may show an error.
Rated 16A at 125/250VAC with 0.187" (4.8 mm) terminals and an overall size of 27.8 x 10.3 x 15.9 mm. Microwaves use several door switches, and each does a different job. This is the normally open type; it will not replace normally closed or common-type switches.
⚠️ Critical Safety Part — Switch Type And Position Must Match Exactly Door interlock switches work together as a safety system. Installing the wrong type (normally open vs. normally closed) or putting a switch in the wrong position can let the microwave run with the door open, a serious radiation hazard. Replace each switch with the exact same type in the exact same position, and have the interlock system tested after replacement. If you are not qualified to service microwave ovens, use a trained technician.

Installation Notes
⚠️ Unplug Microwave And Beware Of The High Voltage Capacitor Unplug the microwave before starting and never operate it with the cabinet open. The high voltage capacitor can hold a lethal charge even after the microwave is unplugged. If your repair requires removing the outer cabinet, discharge the capacitor safely first, or have a qualified technician do the work.
⚠️ Photograph Switch Positions Before Removing Anything Several door switches are often mounted close together. Before disconnecting anything, photograph each switch's position and wiring so the new normally open switch goes back exactly where the old one came from. Some switch tabs and mounts are fragile, so remove the old switch carefully. After installing, have the door interlock system tested before using the microwave.
Frequently Asked Questions
My microwave won't start. Is this the part I need?
A failed door switch is a common cause, but a microwave has several switches and other parts can cause the same symptom. Identify which switch failed and confirm it is normally open before ordering.
Is this switch normally open or normally closed?
This is a normally open (NO) switch. It is not interchangeable with normally closed switches, which do a different job in the interlock system.
Is this an OEM or aftermarket part?
This is an aftermarket replacement from XPARTCO that cross-references many OEM numbers, including Frigidaire part 5304509460. If you specifically need a genuine Frigidaire part, contact our support team.
Will this fit my microwave?
It is listed for many microwaves and microwave/hood combinations across major brands, but compatibility varies by model. Check your full model number and the type and position of your original switch, or contact our support team and we'll verify it before you order.
