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 CTH18EAXERWH: WR51X447 (Refrigerator Defrost Heater), WR86X96 (Refrigerator Filter Dryer), WR2X3198 (Refrigerator Fan Blade).
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.

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.

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 CTH18EAXERWH: WR50X131 (Thermostat).
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.

Before you buy
Match CTH18EAXERWH 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.
