Common failure areas on this model
The confirmed parts above group into a handful of failure areas. Here is what each points to and how to check it before you order anything.
General hardware and mounting parts
Symptom: A small mechanical or mounting part has failed, cracked, or gone missing.
Check: Compare the physical shape and mounting points to the original piece, and confirm the exact part number against your model plate before ordering.
Parts in this group on FFMV1645TWA: 5304509459 (Kenmore Elite Microwave Door Interlock Switch 5304509459), 5304509479 (Crosley Microwave Diode), 5304509452 (Kenmore Elite Microwave Noise Filter), 5304509457 (Kenmore Elite Microwave Latch Body 5304509457), 5304509458 (Crosley Microwave Door Interlock Switch Lever), 5304509460 (Crosley Microwave Door Interlock Switch 5304509460), 5304509451 (Kenmore Elite Microwave Fuse 5304509451).
Heat control (thermostats, fuses, heating element)
Symptom: The appliance runs but heats or cools inconsistently, or shuts off partway through a cycle.
Check: With the appliance unplugged, check continuity across the part with a multimeter -- no continuity means it has failed.

Storage, trim and cosmetic hardware
Symptom: A cracked shelf, broken door bin, worn hinge, or missing trim piece -- cosmetic and storage wear rather than a functional breakdown.
Check: Match the physical dimensions and mounting tabs of the old part before ordering; these pieces are often model-specific even between visually similar models.
Parts in this group on FFMV1645TWA: 5304509435 (Kenmore Elite Microwave Waveguide Cover).
Controls, timers and wiring
Symptom: A cycle that doesn't advance, an unresponsive display, or the unit not starting at all.
Check: Look for burn marks or a burnt smell near the board or terminals, and check whether buttons and knobs respond -- a unit that powers on but won't cycle often traces back to this group.

Before you buy
Match FFMV1645TWA exactly against the model and serial plate on the appliance itself before ordering anything — a single mismatched character can point to a different production run with different parts. Then check the part number printed or stamped on the part you are replacing against the part numbers in the table above; the printed number is the most reliable way to confirm fitment when a model has gone through multiple production runs. RepairKitHub does not sell parts directly — every part link above routes to an Amazon search for that part number so you can compare current listings and sellers yourself.
How to confirm this is your model
On most microwaves, the model and serial plate sits inside the door frame. Match every character exactly, including letters and dashes at the end — appliance model numbers often have similar prefixes but different suffixes for different production runs.
