What are the most commonly replaced parts in a refrigerator?
The most commonly replaced parts in a refrigerator are the ones that wear out, get damaged, or directly affect cooling and dispensing. For a GE TFX28PBBABB side-by-side, we most often see water filtration and dispenser parts, defrost components, fan motors, light parts, and door sealing or storage hardware replaced.
Most common refrigerator parts people replace
These are the parts that typically fail first or get replaced due to symptoms like warm temps, frost buildup, leaks, noise, or poor ice and water dispensing:
- Water filter (taste, flow, and ice quality)
- Water inlet valve (no water to dispenser or icemaker, slow fill)
- Evaporator or condenser fan motor (warm temps, noise, weak airflow)
- Defrost parts (frost buildup on the back wall, warm fridge section)
- Door gaskets and door switches (moisture, frost, lights staying on)
- Light bulb or lamp socket (no interior light)
- Drawer slides, shelf supports, bins (cracks, broken rails, hard-to-slide drawers)
Common replacements we see for GE TFX28PBBABB (examples)
Here are model-matched examples from the parts available for this refrigerator:
| Symptom | Commonly replaced part | What it affects |
|---|---|---|
| Bad taste or slow water flow | Refrigerator filter MWFP | Water and ice quality, dispenser flow |
| Frost buildup, warming | Refrigerator defrost thermostat WR50X122 | Defrost cycling and evaporator protection |
| Noisy or warm fridge/freezer | Refrigerator evaporator fan motor WR60X10008 | Cold air circulation |
| No water to icemaker/dispenser | Refrigerator water inlet valve assembly WR49X10043 | Water supply into the refrigerator |
| Dispenser not actuating | Refrigerator dispenser lever WR17X3089 | Ice and water dispensing |
Why it matters
Replacing the right “high-wear” part first saves time and prevents food spoilage. For example, a clogged filter can mimic a valve problem (low flow), and a failed fan motor can look like a sealed-system cooling issue because temperatures rise even though the compressor runs.
Quick triage tips before you order
We recommend these quick checks to narrow down the likely part:
- Confirm the temperature settings and that vents are not blocked by food packages
- Listen for fan noise (evaporator fan in freezer area; condenser fan near the back/bottom)
- Check for heavy frost on the freezer back panel (points to defrost system)
- Inspect door seals for gaps, tears, or areas that do not grip paper
- For dispenser issues, verify household water supply is on and the line is not kinked

What is the most common problem with a GE refrigerator?
The most common GE refrigerator complaint is not cooling properly (fresh food warm, freezer warming, or temperatures swinging). On the GE TFX28PBBABB, the most frequent root causes are airflow problems, dirty condenser area, or a defrost-system issue that lets frost block the evaporator.
Quick checks we recommend first
- Confirm the controls are set correctly (typical targets: 0°F freezer, 37°F fresh food).
- Make sure vents inside both compartments are not blocked by food packages.
- Listen for the evaporator fan; if it is not running, cooling will suffer.
- Check for heavy frost on the freezer back wall (a strong sign of a defrost problem).
- Clean dust from the condenser area and verify the condenser fan is running.
- Verify the doors seal and close fully; warm air leaks mimic “not cooling.”
Common causes and the parts that often fix them
If you see frost buildup or the unit cools for a while then warms up, the defrost system is a top suspect.
| Symptom you notice | Most likely area | Example part for TFX28PBBABB |
|---|---|---|
| Freezer cold but fresh food warm | Airflow/evaporator fan | Refrigerator evaporator fan motor WR60X10008 |
| Heavy frost on freezer back wall | Defrost system | Refrigerator defrost thermostat WR50X122 or refrigerator defrost control WR9X489 |
| Water dispenser slow or tastes off | Water filtration | Refrigerator filter MWFP |
| Interior light out | Lighting | 40A15/22 40A15 |
Why it matters
A “not cooling” problem is often progressive: restricted airflow and frost buildup force longer run times, raise food-safety risk, and can lead to more expensive failures if ignored.
Helpful DIY skill for troubleshooting
When diagnosing fans, thermostats, and controls, a meter test is often the fastest way to confirm a failed component; see how to use a multimeter to test electrical parts video.

Where can I buy discontinued refrigerator parts?
For your GE TFX28PBBABB side-by-side refrigerator, the best place to start is the model-specific parts list for currently available replacements. If an item is discontinued, we recommend matching by model number and part ID, then checking for approved substitute parts or compatible assemblies.
Best ways to find a replacement when a part is discontinued
- Search the parts list by your exact model number: TFX28PBBABB
- Compare the failed part’s ID or number to current replacements (sometimes the part is superseded)
- Consider replacing the related assembly instead of a single internal piece
- Use your refrigerator’s symptom to identify the most likely system (cooling, defrost, ice and water, lighting)
- Confirm fit before ordering by matching the part description and where it installs
Commonly needed parts that are available for this model
If you are chasing a “discontinued part” because of a common failure, these in-stock parts often solve the underlying issue:
| Symptom | What to check first | Example part for TFX28PBBABB |
|---|---|---|
| Bad taste/odor, slow water flow | Water filter | Refrigerator filter MWFP |
| Frost buildup, warm fridge section | Defrost system | Refrigerator defrost thermostat WR50X122 |
| No water to dispenser/ice maker | Water valve and supply | Refrigerator water inlet valve assembly WR49X10043 |
| Lights out or flickering | Bulb/socket/switch | 40A15/22 40A15 |
Why it matters
Discontinued parts are often replaced by updated part numbers or sold as larger assemblies. Matching by model number (TFX28PBBABB) and the exact part ID helps you avoid ordering a look-alike that will not mount, seal, or connect correctly.
