General hardware and mounting parts

Symptom: A small mechanical or mounting part has failed, cracked, or gone missing.

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 KEMC308HBL3: WP4455526 (Range Door Hinge Left Or Right Side), 4375412 (Mounting Bracket), 4375413 (Mounting Bracket), 5304505675 (Electrolux Microwave Waveguide Cover), 5304505103 (Washer Door Lock Flange Cover), WP4451009 (Torsion Spring - Black/White/Biscuit - Right side), 4452395 (Microwave Door Torsion Spring), 4452220 (Convection Rack - Short), 5304505353 (Dryer Lint Screen Housing), WP4450038 (Range Control Panel Vent Screw), W10877169 (Dishwasher Dishrack Guide), 4450800 (SCREW,8-32 X.375 MTR SC), 814381 (Hinge Pin Kit).

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.

Parts in this group on KEMC308HBL3: 4375436 (Capacitor), W10888661 (Electric Control Board).

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.

Parts in this group on KEMC308HBL3: 4375279 (Wall Oven Microwave Safety Thermostat).

Interior lighting

Symptom: The interior light doesn't turn on when the door opens.

Check: Confirm power is reaching the socket, then check the door-activated light switch before assuming the bulb itself is at fault.

Parts in this group on KEMC308HBL3: WPW10440740 (Microwave Halogen Bulb), WP4448972 (Oven Halogen Light Assembly).

Drive system (belts, pulleys, motors)

Symptom: A drum or tub that won't turn, a burning-rubber smell, or a loud thump or squeal during a cycle.

Check: With power off, turn the drum or tub by hand -- resistance or grinding points to the motor or a bearing, and a cracked, glazed, or snapped belt is visible once the cabinet is open.

Parts in this group on KEMC308HBL3: 5304507405 (Dishwasher Dishrack Track Roller Assembly).

Door, lid switches and latches

Symptom: The appliance won't start, or stops, unless the lid or door is fully latched shut.

Check: Listen for an audible click when the lid or door closes. No click, or a visibly cracked plastic tab on the latch, points to this part.

Parts in this group on KEMC308HBL3: W10211972 (Door Switch - 250V).

Before you buy

Match KEMC308HBL3 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.
