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.

Door and drum seals

Symptom: A door that won't stay sealed, causing warm spots inside or the compressor running longer than it should.

Check: Close the door on a strip of paper and pull it out; if it slides free with little resistance, the gasket has lost its grip and should be checked against your model's part number.

Parts in this group on 590: 2359314 (Gasket), SZ0573 (Door Gasket), WP465151004 (Door Gasket).

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 590: 705627 (Grommet), TKK30901S (Home Electronics Cover), 321173 (Toro Grommet), 6200130 (Sub-Zero Refrigerator Screw), WP74006636 (Range Oven Door Outer Panel (White)), DA6308646A (Samsung Refrigerator Door Bin), 240599301 (Refrigerator Drawer Cover Frame), 240534701 (Galaxy Refrigerator Door Shelf Rail 240534701).

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.

Parts in this group on 590: 4201460 (Sub-Zero Refrigerator Water Inlet Valve).

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.

Parts in this group on 590: SZ4200520 (Ice Maker Assembly).

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.

Parts in this group on 590: SM0740 (Condenser Fan Motor).

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 590: 7014669 (Sub-Zero Refrigerator Light Bulb).

Controls, timers and wiring

Symptom: The control board or display isn't responding, temperature settings won't change, or the unit won't power on 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 590: W10845086 (Dryer Electronic Control Board).

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.

Parts in this group on 590: W11384469 (Refrigerator Door Switch).

Before you buy

Match 590 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.
