If your LG refrigerator is not cooling properly, it could be due to a faulty start relay. The start relay is a small electrical component that helps the compressor start up. If the start relay is not working properly, the compressor will not be able to start and the refrigerator will not be able to cool.
Testing the start relay is a relatively simple process that can be done with a few basic tools. Here are the steps on how to test lg refrigerator start relay:
1. Unplug the refrigerator from the power outlet.
2. Locate the start relay.
The start relay is usually located on the back of the refrigerator, near the compressor. It is a small, black box with two or three terminals.
3. Disconnect the wires from the start relay.
Use a screwdriver to disconnect the wires from the start relay. Be careful not to damage the wires.
4. Test the start relay with a multimeter.
Set the multimeter to the ohms setting. Touch one probe of the multimeter to each terminal on the start relay. The multimeter should read zero ohms if the start relay is good. If the multimeter reads infinity ohms, the start relay is bad and needs to be replaced.
5. Reassemble the refrigerator.
Once you have tested the start relay, reassemble the refrigerator. Be sure to reconnect the wires to the start relay and plug the refrigerator back into the power outlet.
6. Test the refrigerator to make sure it is cooling properly.
Once the refrigerator is reassembled, test it to make sure it is cooling properly. Place a thermometer in the refrigerator and set it to the coldest setting. The refrigerator should cool down to the set temperature within a few hours.
Troubleshooting Tips
If you have tested the start relay and it is good, but the refrigerator is still not cooling properly, there could be another problem. Here are a few troubleshooting tips:
- Check the power cord to make sure it is plugged into a working outlet.
- Check the thermostat to make sure it is set to the correct temperature.
- Clean the condenser coils on the back of the refrigerator.
- Check the door gaskets to make sure they are sealing properly.
- If you have tried all of these troubleshooting tips and the refrigerator is still not cooling properly, you may need to call a qualified appliance repair technician.
Wrap-Up
Testing the start relay on an LG refrigerator is a relatively simple process that can be done with a few basic tools. If you are having problems with your LG refrigerator not cooling properly, testing the start relay is a good place to start.
