Testing Defrost Components
When your Whirlpool refrigerator stops defrosting, it may be due to a faulty component. Testing the defrost components can help identify the problem. Follow these steps to check the defrost heater and thermostat.
Checking The Defrost Heater
The defrost heater helps melt frost off the evaporator coils. A malfunctioning heater can cause frost buildup. Here’s how to check it:
- Unplug the refrigerator for safety.
- Locate the defrost heater near the evaporator coils.
- Use a multimeter to test the heater’s continuity.
A working heater should show continuity. If the multimeter shows no reading, the heater is faulty and needs replacement.
Inspecting The Defrost Thermostat
The defrost thermostat monitors the temperature of the evaporator coils. It signals the heater to turn on when needed. Follow these steps to inspect it:
- Unplug the refrigerator to ensure safety.
- Find the defrost thermostat on the evaporator coils.
- Use a multimeter to test the thermostat’s continuity.
The thermostat should show continuity when cold. If it doesn’t, the thermostat is defective and requires replacement.
Replacing Faulty Parts
Sometimes, your Whirlpool refrigerator defrost system might fail. Faulty parts could be the reason. Replacing these parts can solve the issue. Here, we will explain how to replace two crucial parts: the defrost heater and the defrost thermostat.
Installing A New Defrost Heater
First, unplug the refrigerator. Safety is very important. Next, remove the freezer shelf. Locate the back panel inside the freezer. Unscrew the panel and set it aside.
You will now see the defrost heater. It’s usually at the bottom. Disconnect the heater’s wires carefully. Remove the screws holding the heater. Take out the faulty heater.
Place the new defrost heater in the same spot. Secure it with screws. Reconnect the wires to the new heater. Make sure they are tight.
Replace the back panel and the freezer shelf. Finally, plug the refrigerator back in. Your defrost heater is now replaced.
Replacing The Defrost Thermostat
Unplug the refrigerator for safety. Open the freezer and remove the shelf. Locate the back panel inside the freezer. Unscrew and remove this panel.
The defrost thermostat is usually clipped to the evaporator coils. Carefully unclasp it. Disconnect the wires from the old thermostat. Remove the faulty thermostat.
Take the new defrost thermostat. Connect the wires to it. Clip it back onto the evaporator coils. Make sure it is secure.
Reattach the back panel. Put the freezer shelf back in place. Plug in the refrigerator. Your defrost thermostat is now replaced.
Reassembling The Refrigerator
After fixing the defrost issue, the next step is to reassemble the refrigerator. This involves putting back the shelves and drawers and restoring power. Follow these steps carefully to ensure your Whirlpool refrigerator is back in perfect working condition.

Final Checks
After fixing your Whirlpool refrigerator defrost issue, it’s crucial to perform final checks. These checks ensure everything works correctly and your fridge stays in top shape. Let’s go through these important steps.
Monitoring Temperature
First, keep an eye on your refrigerator’s temperature. Use a thermometer to check both the fridge and freezer compartments.
- Refrigerator temperature: 37°F (3°C)
- Freezer temperature: 0°F (-18°C)
If the temperatures are off, adjust the settings. Wait 24 hours and recheck. Consistent temperatures mean your fridge is cooling properly.
Ensuring Proper Operation
Next, confirm your fridge is operating smoothly. Listen for unusual noises. The compressor and fans should run quietly.
Check the defrost cycle. Observe if frost is forming on coils. If frost is present, the defrost system might still have issues.
Finally, test the door seals. Close the door on a piece of paper. If the paper slides out easily, the seal may need replacing.
| Final Check | What to Look For |
|---|---|
| Temperature | 37°F (fridge), 0°F (freezer) |
| Noise | Quiet compressor and fans |
| Defrost Cycle | No frost on coils |
| Door Seals | Paper does not slide out |
Performing these final checks ensures your Whirlpool refrigerator stays in excellent condition. Always monitor its performance regularly.
