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.
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.

Ice maker and dispenser system
Symptom: No ice production, a jammed dispenser chute, or water leaking into the ice bin.
Check: Confirm water is actually reaching the icemaker (check the inlet valve and fill tube for a freeze-up), and check that the auger or dispenser motor turns freely without binding.

Water inlet and drainage
Symptom: The icemaker or dispenser isn't getting water, or a supply-line fitting is leaking.
Check: Check that the water inlet valve is receiving supply pressure and that its screen filter isn't clogged, and inspect the fill tube and fittings for a leak or freeze-up.

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.

Cooling system (compressor, condenser, evaporator)
Symptom: The refrigerator or freezer runs warm, the compressor cycles on and off rapidly, or frost builds up heavily inside.
Check: Listen for the compressor and condenser fan actually running, feel the condenser coils for heat, and check the evaporator coil for an ice layer that blocks airflow.

Door, lid switches and latches
Symptom: A door that doesn't latch or stay closed, letting the interior light stay on or warm air get in.
Check: Check that the latch or catch engages fully when the door swings shut, and look for a cracked or worn strike plate or spring mechanism.

Before you buy
Match LRSC21935SB 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 refrigerators, the model and serial plate sits inside on a side wall or behind the bottom grille. 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.
Other refrigerator models
These model numbers sort close to this one in the catalog for the same appliance type. The brand is not confirmed to match, but the model number range is close.
