Mounting Plate
★★★★★

Part #W11025649
This mounting plate is sourced directly from the original manufacturer for use with microwaves. It is a metal plate designed to support a microwave by attaching the microwave to the wall studs. If the mounting plate wears down or becomes damaged, it will cause the microwave to tilt and become unstable, potentially damaging the appliance and the wall it is attached to. Therefore, it is important to replace the plate promptly. First disconnect the microwave from the power source and locate the fasteners that hold the mounting plate. Detach the old plate and align the new one with the existing mounting holes. Secure the plate and check that the microwave is stable and unmoving.

Part #W11707984
If your microwave is not turning on it could be due to your fuse needing to be replaced. This part protects the microwave by shutting it off if there is an electrical surge. This fuse is just over an inch long, is metallic on both ends and ceramic in the middle. Before beginning this repair, unplug the appliance and wait a few minutes before starting. Remove the outer cabinet which is held in place with two screws. You will then locate the power cord which will lead you to the fuse holder. Determine if the fuse has blown. Using an ohmmeter, you should be able to figure out if it has blown. A proper reading is zero ohms, if it reads as anything else then your fuse has in fact blown. Simply snap the old fuse out of place and place the new one in.

This damper is an authentic OEM replacement assembly used in microwave/range hood combos. It includes the damper door and frame. It is designed to direct the flow of air through the vent duct, and the release of steam and heat from the appliance during cooking.
