A refrigerator’s thermostat plays a crucial role in maintaining the ideal temperature to preserve your food. If your Kenmore refrigerator is not cooling properly, testing the thermostat can help you determine if it’s malfunctioning. This comprehensive guide will walk you through the steps on how to test Kenmore refrigerator thermostat, empowering you to diagnose and resolve any issues.
Tools and Materials
Before you begin, gather the following tools and materials:
- Multimeter
- Screwdriver
- Flashlight (optional)
Safety Precautions
- Unplug the refrigerator before starting any work.
- Wear gloves to protect your hands from sharp edges.
- Be cautious when handling electrical components.
Step-by-Step Testing Procedure
1. Locate the Thermostat
The thermostat is usually located inside the refrigerator compartment, behind a cover near the top. Locate it by following the capillary tube that leads from the evaporator coils.
2. Remove the Cover
Using a screwdriver, carefully remove the cover to expose the thermostat.
3. Identify the Terminals
The thermostat has two terminals: one for power and one for the compressor. Identify them by their markings or by tracing the wires.
4. Test for Continuity
Set your multimeter to the continuity setting. Touch one probe to each terminal. If the multimeter beeps or displays a low resistance reading, the thermostat is providing continuity.
5. Check for Voltage
Set your multimeter to the AC voltage setting. Touch one probe to the power terminal and the other probe to the compressor terminal. If you get a voltage reading, the thermostat is receiving power.
6. Test the Temperature Control
Turn the temperature control dial to different settings. The multimeter reading should change as the thermostat adjusts the temperature.
7. Observe the Compressor
While testing the thermostat, observe the compressor. It should turn on and off as the thermostat regulates the temperature.
Troubleshooting
If the thermostat fails the tests, it’s likely malfunctioning. Replace it with a new Kenmore refrigerator thermostat. If the thermostat passes the tests but the refrigerator is still not cooling properly, check other components such as the compressor, evaporator coils, or condenser coils.
Resetting the Thermostat
If the thermostat is functioning properly but the refrigerator is not cooling, you can try resetting it. To do this, unplug the refrigerator for 10 minutes and then plug it back in. This may resolve any minor glitches or errors.
Wrapping Up
Testing the Kenmore refrigerator thermostat is a straightforward process that can help you diagnose and resolve cooling issues. By following these steps, you can ensure that your refrigerator is operating efficiently and keeping your food fresh.
