Microwave Door Latch Assembly
Switches can be purchased separately. Frigidaire produces items under its own brand and Electrolux, and it also supplies products to Sears-Kenmore. This specific door latch hook, designated with part number 5304440289, is designed for use in microwaves.
The latch hook functions to secure the microwave door when closed and supports the door switch mechanism.
Given the potential danger from high-voltage capacitors that might retain an electrical charge even after unplugging, it is advisable that a certified technician perform the installation.
