What To Know
- A faulty control board can cause various issues, such as the oven not heating properly, the display not working, or the oven not turning on at all.
- Once the new control board is installed, plug the oven back into the power outlet and turn it on.
- The cost of a Frigidaire oven control board varies depending on the model and availability.
If your Frigidaire oven is malfunctioning, the control board may be the culprit. A faulty control board can cause various issues, such as the oven not heating properly, the display not working, or the oven not turning on at all. If you suspect that your oven’s control board is faulty, you can test it yourself using a multimeter. Here’s a step-by-step guide on how to test a Frigidaire oven control board:
1. Safety Precautions
Before starting any electrical work, it’s essential to take safety precautions. Ensure the oven is unplugged from the power outlet and allow it to cool down completely. Wear insulated gloves and safety glasses for protection.
2. Locate the Control Board
Open the oven door and locate the control panel. The control board is usually situated behind the panel, held in place by screws. Remove the screws and carefully pull out the control board.
3. Identify the Terminals
The control board has several terminals connected to wires. Each terminal serves a specific function, such as power supply, temperature sensor input, and relay outputs. Refer to the oven’s service manual or wiring diagram to identify the terminals you need to test.
4. Set the Multimeter
Set your multimeter to the “AC voltage” setting. The voltage range should be appropriate for the power supply of your oven (usually 120V or 240V).
5. Test the Power Supply
Connect the multimeter probes to the power supply terminals on the control board. The multimeter should display the voltage supplied to the board. If it reads zero or a significantly different value than expected, the power supply may be faulty.
6. Test the Temperature Sensor Input
Connect the multimeter probes to the temperature sensor input terminals. The multimeter should read a voltage that corresponds to the temperature inside the oven. If the reading is incorrect or doesn’t change when the oven temperature changes, the temperature sensor or its wiring may be faulty.
7. Test the Relay Outputs
Connect the multimeter probes to the relay output terminals. When the oven is turned on, the multimeter should display a voltage across the terminals. If it doesn’t, the relay may be faulty.
8. Troubleshooting
If any of the tests fail, the control board may be faulty and need to be replaced. However, before replacing the control board, check the wiring connections to ensure they are secure and not damaged.
9. Replacing the Control Board
If the control board is faulty, you will need to replace it. Purchase a new control board that is compatible with your Frigidaire oven model. Follow the manufacturer’s instructions for installing the new control board.
10. Testing the Oven
Once the new control board is installed, plug the oven back into the power outlet and turn it on. Test the oven’s functionality to ensure it is working correctly.
Final Thoughts
Testing a Frigidaire oven control board is a relatively straightforward procedure. By following these steps, you can determine if the control board is faulty and take the necessary steps to repair or replace it. Remember to take safety precautions and refer to the oven’s service manual for specific instructions.
