Diy diagnostics: step-by-step guide to testing whirlpool oven control boards
What To Know
- Using a multimeter set to the continuity setting, test the continuity of the wires connected to the control board.
- Connect a multimeter set to the AC voltage setting to the terminals on the control board.
- The cost of a Whirlpool oven control board can vary depending on the model, but it typically ranges from $100 to $300.
A malfunctioning control board can cause a wide range of issues in your Whirlpool oven, from erratic temperature control to complete failure. If you suspect that the control board is faulty, it’s important to test it before replacing it. Here’s a step-by-step guide on how to test a Whirlpool oven control board:
Safety Precautions
Before you begin testing the control board, ensure you take appropriate safety precautions:
- Turn off the power to the oven at the circuit breaker.
- Allow the oven to cool completely.
- Wear gloves and safety glasses to protect yourself from electrical shock and heat.
Removing the Control Board
1. Locate the control board. It is typically found behind the control panel on the front of the oven.
2. Remove the screws holding the control panel in place.
3. Carefully pull the control panel forward to expose the control board.
4. Disconnect the wires connected to the control board.
Testing the Control Board
1. Visual Inspection:
Inspect the control board for any obvious signs of damage, such as burn marks, broken traces, or loose connections.
2. Continuity Test:
Using a multimeter set to the continuity setting, test the continuity of the wires connected to the control board. Ensure that there is continuity between the terminals on the board and the corresponding terminals on the wires.
3. Voltage Test:
Connect a multimeter set to the AC voltage setting to the terminals on the control board. Turn on the power to the oven and check for the presence of voltage. The voltage should be within the specified range for your oven model.
4. Function Test:
If the continuity and voltage tests pass, perform a function test by cycling through the oven’s functions. Use the control panel to set different temperatures, modes, and timers. Observe whether the oven responds appropriately to your commands.
Troubleshooting Common Issues
1. Oven Not Heating:
- Check the continuity of the wires connected to the heating element.
- Test the heating element for continuity.
- Replace the heating element if necessary.
2. Oven Temperature Fluctuates:
- Check the temperature sensor for continuity.
- Replace the temperature sensor if necessary.
- Calibrate the oven using the manufacturer’s instructions.
3. Oven Not Responding:
- Check the continuity of the wires connected to the control board.
- Test the control board for voltage.
- Replace the control board if necessary.
Reinstalling the Control Board
1. Connect the wires to the control board.
2. Slide the control panel back into place.
3. Secure the control panel with screws.
4. Turn on the power to the oven.
Final Thoughts
Testing a Whirlpool oven control board can help you diagnose issues and determine if it needs to be replaced. By following these steps carefully and taking appropriate safety precautions, you can troubleshoot your oven and restore it to proper working order.
