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 511: S97011852 (Grille), 1259004 (Porter Cable 1 BUSHING AND SPACER), 1259007 (Porter Cable Thumb Screw), S97011851 (Air Grille), S97014186 (Grille), 802422 (REAR ENDSHIELD TOP SCREW), 7100411 (Lawn & Garden Equipment Screw), 7320583 (Lawn & Garden Equipment Spring), 7270471 (Hydraulic Tube), 9500750 (Lawn & Garden Equipment Spacer), 7500743 (Lawn Mower Spacer), 75305424 (Log Splitter Log Tray Support Bracket), 7320194 (MTD Lawn Mower Spring Pin).

Heat control (thermostats, fuses, heating element)

Symptom: The refrigerator's temperature reads inconsistently, or the compressor and defrost cycle seem out of step with how warm or cold it actually is inside.

Check: A thermistor that has drifted or failed reports the wrong temperature to the control board, so compare the compartment's actual temperature to what the display or dial shows.

Parts in this group on 511: 4200930 (Sub-Zero Refrigerator Thermostat).

Drive system (belts, pulleys, motors)

Symptom: The evaporator or condenser fan doesn't seem to be running, or a new grinding or rattling noise is coming from the back or bottom of the unit.

Check: With the unit unplugged, check that the fan in question spins freely by hand, then listen once it's back on for a grinding or rattling sound rather than a smooth hum.

Parts in this group on 511: 301291S (Drive Belt), 7015690 (Sub-Zero Refrigerator Roller Bearing), 7190353 (Coupling Shield), 9180686 (Log Splitter Pump Flex Coupling).

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 511: 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 511: SM0740 (Condenser Fan Motor).

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 511: 78103560637 (Log Splitter Floating Gib Plate).

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 511: 7014669 (Sub-Zero Refrigerator Light Bulb).

Before you buy

Match 511 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.
