Frigidaire 5304509643 Microwave Shelf Support

Product Description

The FRIGIDAIRE 5304509643 is an OEM replacement microwave shelf support designed to hold and stabilize the internal rack at its designated position during operation. Mounted on the interior side wall of the microwave cavity, the support fits into molded slots and interfaces with the shelf legs through a clip-in or locking design. This part maintains proper rack alignment at multiple height levels and keeps the shelf securely seated throughout heating and cooking cycles. It is typically installed by appliance service technicians handling interior component repairs on over-the-range or countertop microwave units.

This shelf support is suited for residential microwave applications where the original rack support has become cracked, broken, or missing, causing the internal rack to shift or become unstable during use. It is specified for use in either the left rear or right front position within the microwave cavity, making it a dual-placement part. Compatible brands include Electrolux, Frigidaire, Gibson, Kelvinator, and Westinghouse microwave models that use this support configuration.

Installation Notes

Installation is typically performed by a qualified appliance service technician.

The support snaps or clips into the molded wall slots without special tools in most configurations. Confirm the placement position matches the original support location before seating the part.
