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 MST20GAZAWW: WR51X463 (Refrigerator Defrost Heater Harness), WR87X471 (Comp Rpl Kit), WR86X96 (Refrigerator Filter Dryer).
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 MST20GAZAWW: WR13X742 (Door Hinge Pin, Lower), WR13X741 (Door Hinge Pin, Lower).
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 MST20GAZAWW: WR2X9391 (Technician Refrigerator Light Socket), WR23X193 (Light Switch).
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 MST20GAZAWW: WR50X122 (Refrigerator Defrost Bi-Metal Thermostat).
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 MST20GAZAWW: WR62X79 (Refrigerator Run Capacitor).
Before you buy
Match MST20GAZAWW 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.
