What are the most commonly replaced parts in a refrigerator?
The most commonly replaced refrigerator parts are the ones tied to temperature control, airflow, and sealing. For Gladiator model GAFZ30FDGB01, frequent replacements include the door gasket, evaporator fan parts, and temperature sensors, plus defrost components when cooling problems show up.
Most common refrigerator parts (and what they affect)
- Door gasket: prevents warm air leaks that cause frost, sweating, and long run times (see refrigerator door gasket (black) W11102846).
- Evaporator fan parts: move cold air through the cabinet; failures cause warm temps and uneven cooling (see evaporator motor WPW10359880 and refrigerator evaporator fan blade WP2169142).
- Temperature sensor (thermistor): tells the control how cold it is; a bad sensor can cause overcooling or not cooling enough (see refrigerator thermistor WPW10383615).
- Defrost heater: melts frost off the evaporator; failures often lead to heavy frost and weak airflow (see refrigerator defrost heater WPW10316428).
- Start relay: helps the compressor start; a bad relay can cause clicking and no cooling (see combination W10873801).
- Lights and door hardware: common “wear” items such as LEDs and hinge pieces (see led - lamp 1 W11338583 and refrigerator door hinge thimble WP2314293).
Quick symptom-to-part guide
| Symptom | Most likely part area | Example part for GAFZ30FDGB01 |
|---|---|---|
| Frost buildup, moisture, warm cabinet | Door sealing | W11102846 door gasket |
| Warm temps, weak airflow, noisy fan | Evaporator fan system | WPW10359880 motor, WP2169142 blade |
| Temps swing up and down | Temperature sensing | WPW10383615 thermistor |
| Fan runs but airflow is blocked by ice | Defrost system | WPW10316428 defrost heater |
| Clicking, compressor not starting | Start components | W10873801 start relay |
Why these parts get replaced most
These components run constantly or are exposed to heat, moisture, and door slams. When they wear out, the refrigerator either loses cold air (gasket), stops moving cold air (fan), or “misreads” temperature (thermistor), which quickly shows up as poor cooling.

If you suspect an airflow problem, follow the checks in how to fix your evaporator cooling fan before ordering parts.

Why is my gladiator refrigerator freezer not cooling?
If your Gladiator refrigerator model GAFZ30FDGB01 freezer isn’t cooling, the most common causes are an airflow problem (evaporator fan not running or frost blocking vents), a defrost failure, or a temperature-sensing/control issue. Start with quick airflow and door-seal checks, then move to fan and defrost diagnostics.
Quick checks (5 to 10 minutes)
- Confirm the freezer temperature is set colder (target is 0°F; fresh food is 37°F).
- Make sure the door closes fully and the gasket seals all the way around.
- Look for heavy frost on the back interior panel of the freezer (a strong defrost-system clue).
- Verify vents are not blocked by food packages or bins.
- Listen for the evaporator fan when the door switch is pressed (fan should run during cooling).
Most likely causes and what they look like
| Symptom | Most likely cause | What to check next |
|---|---|---|
| Freezer warm, fridge also warm | Evaporator fan not moving air | Inspect fan blade and motor; check for ice obstruction |
| Heavy frost on freezer back wall | Defrost system problem | Check defrost heater and airflow path |
| Temps swing, partial cooling | Temperature sensor (thermistor) issue | Check sensor placement and wiring; replace if out of spec |
| Clicking, won’t start cooling | Start relay or compressor issue | Check relay first, then sealed system/compressor |
Parts that commonly fix “freezer not cooling” on GAFZ30FDGB01
These are model-matched parts we often see involved in no-cool or warm-freezer complaints:
- Evaporator motor WPW10359880 (fan motor that circulates cold air)
- Refrigerator evaporator fan blade WP2169142 (broken or slipping blade reduces airflow)
- Refrigerator defrost heater WPW10316428 (failed heater leads to frost buildup and blocked airflow)
- Refrigerator thermistor WPW10383615 (bad sensor can cause incorrect cooling/defrost behavior)
- Combination W10873801 (compressor start relay; clicking or intermittent start symptoms)
Why it matters
A freezer that is not cooling is usually an airflow or defrost issue first. Fixing the fan, clearing frost, or restoring defrost operation prevents warm temperatures, food spoilage, and compressor overwork.

What are the main 5 parts of a refrigerator?
The main five parts that make a refrigerator cool are the compressor, condenser coil, evaporator coil, metering device (capillary tube/expansion device), and a temperature control (thermostat or electronic sensor). On your Gladiator GAFZ30FDGB01, these work together to move heat out of the cabinet and keep food frozen or chilled.
The “core cooling system” (the 5 main parts)
- Compressor: pumps refrigerant through the sealed system (the “heart” of cooling).
- Condenser: releases heat to the room as refrigerant changes from hot gas to liquid.
- Metering device (capillary tube/expansion device): drops refrigerant pressure so it can get cold.
- Evaporator: absorbs heat inside the freezer/refrigerator as refrigerant boils back into a gas.
- Temperature control: tells the system when to run (thermostat or sensor).
Common related parts you may also hear about
These are important, but they support the five core components above:
- Evaporator fan (moves cold air through the cabinet)
- Defrost heater (melts frost off the evaporator)
- Door gasket (keeps warm, moist air out)
Model-related examples (parts we stock for GAFZ30FDGB01)
If you are troubleshooting cooling, these parts commonly come up:
| What it affects | What you might notice | Example part for this model |
|---|---|---|
| Sealed-system pumping | Warm cabinet, compressor issues | Compressor W10233961 |
| Air movement across evaporator | Warm spots, weak airflow, fan noise | Evaporator motor WPW10359880 |
| Temperature sensing/control | Temps swing, runs too long or not enough | Refrigerator thermistor WPW10383615 |
| Defrost performance | Frost buildup, airflow blocked | Refrigerator defrost heater WPW10316428 |
| Cabinet sealing | Condensation, frost, warm air leaks | Refrigerator door gasket (black) W11102846 |
Why it matters
Knowing the five main parts helps you narrow symptoms fast. For example, frost buildup points you toward defrost and airflow parts, while a hot, constantly running unit points you toward temperature sensing, airflow, or sealed-system components.
Next step for troubleshooting
We recommend starting with airflow and temperature sensing checks before sealed-system work:
- Listen for the evaporator fan running
- Check for heavy frost on the evaporator cover
- Verify the door gasket seals all the way around
- Confirm the unit is level and doors close fully

What are the parts of the freezer?
On the Gladiator GAFZ30FDGB01 (listed under refrigerator parts), the freezer cooling system is built around the sealed refrigeration loop (compressor, condenser, metering device, evaporator) plus airflow, defrost, and temperature-sensing components that keep the cabinet at a stable freezing temperature.
Main freezer system parts and what they do
- Compressor: pumps refrigerant through the sealed system to create cooling.
- Condenser (coils and airflow path): releases heat to the room.
- Metering device (capillary tube or similar restriction): drops refrigerant pressure before the evaporator.
- Evaporator: absorbs heat inside the cabinet.
- Evaporator fan system: moves cold air across the evaporator and through the cabinet.
- Defrost system: melts frost so airflow stays strong.
- Temperature sensor (thermistor): reports cabinet temperature so cooling cycles run correctly.
Replaceable parts on this model (examples)
These are common service parts shown for GAFZ30FDGB01:
- Compressor W10233961
- Combination W10873801
- Evaporator motor WPW10359880
- Refrigerator evaporator fan blade WP2169142
- Refrigerator thermistor WPW10383615
- Refrigerator defrost heater WPW10316428
Quick symptom-to-part guide
| Symptom | What to check first | Example part on this model |
|---|---|---|
| Warm cabinet, fan not running | Evaporator fan motor/blade | WPW10359880, WP2169142 |
| Heavy frost, weak airflow | Defrost heater | WPW10316428 |
| Temps swing or run time seems off | Thermistor | WPW10383615 |
| Clicking, won’t start cooling | Start relay or compressor | W10873801, W10233961 |
Why it matters
Knowing which system you are dealing with helps you troubleshoot efficiently: most “not cold enough” complaints come from airflow, defrost, temperature sensing, or start components, not the entire sealed system.
