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 RF378LXMS0: WP9761048 (Infinite Switch), WP6610456 (Clock Control), W10823696 (Surface Radiant Element with Limiter), 8053713 (Bake Element), W10823711 (Element with Limiter 6 Inch - 1200W), WPW10118454 (Range Exterior Door Glass (White)), WP3149404 (Infinite Control Switch, 6"), WPW10308477 (Oven Bake Element), W10856603 (Broil Element), 3148954 (Infinite Switch), 3148951 (Infinite Switch (Silver)), 350930 (Spray Paint - 12 oz. - White), 72017 (Touch-Up Paint - White).

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 RF378LXMS0: WP6610457 (Electronic Control Board w/Overlay), 9757136 (Terminal Block), WPW10326122 (Terminal Block Cover Box).

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 RF378LXMS0: 8053950 (Range Broil Drawer Outer Panel Trim, Lower), WP8522566 (Black Control Knob), 8273888A (Anti-Tip Bracket Kit), 3196566 (Screw), WPW10202217 (Range Door Handle), WPW10330077 (Range Exterior Door Panel (Stainless Steel)), W11219377 (Drawer Panel Front - White), WP8523167 (Range Trim Side (Biscuit Right Hand), WPW10202216 (Range Door Handle (White)), WP8523173 (Door Trim), WP3196164 (Range Screw), W10761014 (Door Trim - Right Side - Black), W10761018 (Door Trim - Left Side - Black), W11594186 (Door Trim (Lower, White)), W10491985 (Screw), 8523171 (Range Door Trim, Left (Black)), 8523165 (Door Trim).

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 RF378LXMS0: WP3195993 (Door Switch).

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 RF378LXMS0: 3196548 (Range 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 RF378LXMS0: 311255 (Light Bulb).

Before you buy

Match RF378LXMS0 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 ranges, the model and serial plate sits behind the storage drawer or on 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.
