Unveiling The Secrets: How To Test Frigidaire Refrigerator Control Board
What To Know
- Connect one probe to the incoming power terminal on the control board and the other to the ground terminal.
- You should get a reading of zero ohms when the timer is in the defrost cycle.
- By following the steps outlined above, you can accurately determine if the control board is causing issues and take the necessary steps to fix it.
Is your Frigidaire refrigerator acting up? A faulty control board could be the culprit. Don’t worry; testing it is easier than you think. Here’s a comprehensive guide to help you diagnose and fix your refrigerator’s control board.
Tools You’ll Need:
- Multimeter
- Screwdriver
- Wire stripper
Safety Precautions:
- Unplug the refrigerator before working on it.
- Wear safety glasses and gloves.
- Discharge any capacitors by touching the terminals with an insulated screwdriver.
Step-by-Step Testing Procedure:
1. Locate the Control Board:
- Remove the back panel of the refrigerator to access the control board.
- It’s usually located near the top or bottom of the refrigerator compartment.
2. Inspect the Board:
- Look for any visible damage, such as burnt components or loose wires.
- If you notice anything unusual, it could indicate a faulty control board.
3. Test the Power Supply:
- Set your multimeter to AC voltage.
- Connect one probe to the incoming power terminal on the control board and the other to the ground terminal.
- You should get a reading of 120 volts.
4. Test the Temperature Sensor:
- Locate the temperature sensor connected to the control board.
- Set your multimeter to resistance.
- Connect the probes to the sensor terminals.
- The resistance should change as you adjust the refrigerator temperature.
5. Test the Defrost Timer:
- Set your multimeter to continuity.
- Connect the probes to the defrost timer terminals.
- You should get a reading of zero ohms when the timer is in the defrost cycle.
6. Test the Compressor Relay:
- Set your multimeter to resistance.
- Connect the probes to the compressor relay terminals.
- You should get a reading of zero ohms when the relay is closed.
7. Test the Evaporator Fan Motor:
- Set your multimeter to AC voltage.
- Connect one probe to the fan motor terminal and the other to the ground terminal.
- You should get a reading of 120 volts when the fan is running.
Troubleshooting:
- If you get no voltage readings, check the power supply to the refrigerator.
- If you get no continuity readings, check the wires and connections.
- If you get incorrect resistance readings, the sensor or component may be faulty.
Summary:
Testing your Frigidaire refrigerator control board is crucial for diagnosing and repairing your appliance. By following the steps outlined above, you can accurately determine if the control board is causing issues and take the necessary steps to fix it. Remember, safety is paramount, so always take precautions when working on electrical appliances.
