GE TPX21BRXABB side-by-side refrigerator Parts

The most common issue we see on GE refrigerators like model TPX21BRXABB is not cooling properly (fresh food warm, freezer warming, or temperatures swinging). In many cases, the root cause is airflow or defrost-related, not the sealed system.

Most common symptoms (and what they usually point to)

• Fridge warm but freezer cold: restricted airflow, iced-up evaporator, or a defrost problem
• Freezer warm and fridge warm: condenser fan issue, dirty condenser coils, or compressor start problem
• Frost building up on the back freezer panel: defrost thermostat/control issue
• Clicking, humming, or repeated start attempts: start relay or run capacitor
• Water under the fridge or inside the fresh food section: clogged defrost drain
• Ice maker or dispenser problems: dispenser/auger parts, solenoids, or ice bucket issues

Quick checks we recommend before replacing parts

1. Confirm temperatures: freezer near 0°F; fridge near 37°F.
2. Check airflow: make sure vents are not blocked by food packages.
3. Inspect for frost: heavy frost usually means the defrost system is not doing its job.
4. Clean condenser coils: dust buildup commonly causes poor cooling and long run times.
5. Listen for the condenser fan (near the compressor): it should run when the compressor runs.

Parts that commonly fix “not cooling” complaints on TPX21BRXABB

Symptom	Common suspect	Example part on this model
Clicking, won’t start, intermittent cooling	Start components	Refrigerator relay WR07X10055
Warm temps, compressor struggles to start	Electrical start support	Capacitor WR55X24064
Frosted evaporator cover, warming fridge	Defrost system	Refrigerator defrost thermostat WR50X122
Frost buildup continues, defrost not cycling	Defrost control	Refrigerator defrost control WR9X489

Why it matters

Cooling problems can look like a “bad compressor,” but on many side-by-side refrigerators the real cause is airflow restriction, dirty coils, or a failed defrost component. Catching that early helps prevent food spoilage and reduces strain on the compressor.

For a GE TPX21BRXABB side-by-side refrigerator, the best place to start is the model-specific parts list for your refrigerator; it shows what is still available and what has been replaced by updated part numbers. If a part is discontinued, we use the part number to help you find compatible substitutes or assemblies.

Best ways to find discontinued parts (and workable replacements)

• Search by model number TPX21BRXABB first, then narrow by the section (freezer door, dispenser, cooling, lighting).
• Search by the original part number from the old part label or parts diagram; many discontinued parts cross to a newer number.
• Check whether an assembly is still sold even if a small component is not (common with dispenser and ice maker parts).
• Compare your symptoms to common failure items; for example, cooling and start issues often involve the start relay or run capacitor.
• If you are unsure, match by location and function (for example: condenser fan motor vs. evaporator fan motor).

Parts on this model that are commonly used in repairs

These are examples of parts currently listed for TPX21BRXABB that may help when you are troubleshooting or replacing a failed component:

Repair area	Example part to check	What it affects
Compressor start	Refrigerator relay WR07X10055	Clicking, no start, intermittent cooling
Compressor electrical	Capacitor WR55X24064	Hard starting, humming, warm temps
Defrost system	Refrigerator defrost thermostat WR50X122	Frost buildup, warm fridge, poor airflow
Dispenser	Refrigerator dispenser lever WR17X3089	Lever not returning, dispenser not actuating

Why it matters

Discontinued refrigerator parts are often replaced by updated designs or sold only as larger assemblies. Starting with the TPX21BRXABB parts list helps us avoid ordering the wrong GE refrigerator part and gets your side-by-side refrigerator back to safe temperatures faster.

Quick tip before you order

• Confirm the part fits TPX21BRXABB (not just a similar TPX21 model).
• Verify the failure first (for example, defrost problems can mimic airflow or fan issues).
• If the part is discontinued, look for a substitute part number or a complete assembly option.

To order replacement parts for your GE TPX21BRXABB side-by-side refrigerator, we recommend using the parts list for this model to match the exact part ID to your appliance, then purchasing the part you need. For dispenser, lighting, and cooling issues, ordering the correct part prevents repeat failures.

How we recommend ordering parts for model TPX21BRXABB

• Confirm the full model number on the rating label: TPX21BRXABB.
• Identify the system you are repairing (ice and water dispenser, defrost, lighting, door hardware, cooling).
• Match the part by part ID (not just the description) to avoid look-alike parts.
• If you are replacing an electrical part, unplug the refrigerator before starting.
• Order the part and keep the packaging until the repair is complete and tested.

Common parts customers order for this model

Here are a few examples of model-matched parts that are commonly replaced:

Repair area	Example part (model-matched)	What it helps fix
Dispenser lever not actuating	Refrigerator dispenser lever WR17X3089	Lever won’t press switch, weak or broken lever
Ice bucket won’t dispense well	Bucket auger WR17X4312	Ice clumping, auger stripped, poor dispensing
Refrigerator light out	40A15/22 40A15	Interior light not working
Defrost problems (frost buildup)	Refrigerator defrost thermostat WR50X122	Frosted evaporator, warm temps, poor airflow

If the part you need is out of stock

• Recheck the part ID to make sure you are viewing the correct item for TPX21BRXABB.
• Look for related parts in the same repair area (for example, defrost control vs. defrost thermostat).
• If you need help confirming the right part or finding an alternative, contact Sears PartsDirect support.

Why it matters

GE refrigerators often use similar-looking components across multiple model families. Ordering by the exact TPX21BRXABB part ID helps ensure proper fit, correct electrical ratings, and reliable cooling, defrost, and dispenser performance.

The most commonly replaced parts in a refrigerator are the ones that wear out from daily use or directly affect cooling and dispensing. For the GE TPX21BRXABB side-by-side refrigerator, we most often see customers replace defrost parts, dispenser components, door hardware, and common electrical start parts.

Most common refrigerator parts people replace

• Door gaskets and door closing hardware (warm air leaks, doors not sealing)
• Defrost system parts (frost buildup, warm freezer, poor airflow)
• Ice and water dispenser parts (no ice dispensing, weak dispensing, stuck lever)
• Fan motors (noise, warm temperatures, poor circulation)
• Compressor start components (clicking, hard starting, intermittent cooling)
• Shelves, bins, and trim (cracks, breakage, missing pieces)
• Light bulbs (burned out interior lighting)

Common replacements we see for this model (examples)

These are examples of parts available for GE TPX21BRXABB that match frequent real-world symptoms:

Symptom	Part category	Example part on this model page
Frost buildup, warming temps	Defrost control/thermostat	Refrigerator defrost control WR9X489, refrigerator defrost thermostat WR50X122
Ice will not dispense or is inconsistent	Dispenser/ice bucket parts	Bucket auger WR17X4312, refrigerator dispenser lever WR17X3089
Clicking, compressor will not start	Start components	Refrigerator relay WR07X10055, capacitor WR55X24064
Interior light out	Lighting	40A15/22 40A15

Quick troubleshooting checks before you buy a part

• Confirm doors close fully and nothing is blocking the seal.
• Check for heavy frost on the freezer back wall (points to defrost trouble).
• Listen for fan noise changes (grinding, squealing, or no fan sound).
• If the unit clicks repeatedly and does not cool, suspect start components.
• For dispenser issues, inspect the ice bucket for clumps and verify the lever moves freely.

Why it matters

Replacing the right “high-wear” part first can restore cooling, prevent food spoilage, and stop repeat icing or dispenser jams. It also helps avoid replacing expensive sealed-system parts when the root cause is a defrost or airflow problem.
