Identifying Symptoms
Understanding the symptoms of a faulty Whirlpool refrigerator control board can save you time and money. Identifying these symptoms early helps you address the issue before it escalates.
Unusual Noises
One of the first signs of control board issues is unusual noises. You may hear clicking, buzzing, or humming sounds. These noises often come from the back of the refrigerator.
- Clicking sounds may indicate relay issues.
- Buzzing or humming sounds could point to electrical problems.
Temperature Fluctuations
Another symptom is temperature fluctuations. Your refrigerator may not maintain a consistent temperature. This can lead to food spoiling faster than usual.
- The freezer might not freeze items properly.
- The fridge might become too warm or too cold.
Check the temperature settings. If they are correct but the problem persists, the control board may be faulty.
Display Errors
The display panel can provide clues about control board issues. Watch for error codes or unresponsive buttons.
| Error Code | Possible Issue |
|---|---|
| CF | Communication failure |
| ER | Temperature sensor error |
If you see these error codes, consult your user manual. It will guide you on further steps.
Initial Checks
Troubleshooting a Whirlpool refrigerator control board involves several steps. The first step is conducting initial checks. These checks help identify common problems quickly. Below are the two main checks: Power Supply and Control Board Reset.
Power Supply
Ensure the refrigerator is plugged in securely. Check the wall outlet for power. You can use a voltage tester to confirm this. If the outlet has no power, try another appliance. This helps verify if the issue is with the outlet.
Inspect the power cord for any damage. A frayed or broken cord can cause issues. Replace it if you find any damage. Confirm that the circuit breaker has not tripped. Reset it if necessary. These steps ensure the fridge gets power.
Control Board Reset
Sometimes, the control board needs a reset. Unplug the refrigerator for about five minutes. This helps the system to reset. After five minutes, plug it back in. Listen for any unusual sounds.
Check if the display panel lights up. If not, the control board might be faulty. You can also press the reset button if your model has one. This button is usually inside the fridge, near the control panel.
If these steps do not work, the control board might need replacement. Always consult the user manual for specific instructions. These checks are simple but can solve many issues.

Visual Inspection
Inspecting the Whirlpool refrigerator control board is crucial. It helps identify common issues that might affect functionality. This section covers three main areas: burn marks, loose connections, and damaged components.
Burn Marks
Look for burn marks on the control board. Burn marks indicate electrical shorts or overheating. These signs often point to component failure. Use a flashlight for a better view. Pay close attention to the board’s surface.
Loose Connections
Loose connections can cause erratic behavior. Check all connectors and wires. Ensure they are firmly attached. Wiggle the connectors gently to see if they are secure. Loose connections can lead to intermittent issues.
| Connection | Status |
|---|---|
| Main Power Connector | Secure |
| Sensor Wires | Secure |
| Fan Connector | Loose |
Damaged Components
Inspect the board for any damaged components. Look for broken capacitors or resistors. These components can affect the refrigerator’s performance. Use a magnifying glass if needed. Damaged parts often appear swollen or cracked.
- Check capacitors for bulges
- Inspect resistors for cracks
- Look for broken solder joints
Replacing damaged components can restore functionality. Always handle the board with care. Wear an anti-static wrist strap for safety.
Testing Components
Testing components is crucial for diagnosing issues with your Whirlpool refrigerator control board. This process ensures each part works correctly. Below are steps to test components effectively.
Multimeter Use
A multimeter is essential for testing electrical components. It measures voltage, current, and resistance.
Here are the steps to use a multimeter:
- Set the multimeter to the correct measurement type.
- Connect the probes to the component.
- Read the values displayed on the screen.
Always ensure safety while using a multimeter. Use insulated tools and avoid touching live wires.
Checking Voltage
Checking voltage is a key step in troubleshooting. You need to verify that each component receives the correct voltage.
Steps to check voltage:
- Set the multimeter to measure voltage.
- Connect the multimeter probes to the component terminals.
- Read the voltage on the multimeter display.
Compare the measured voltage with the expected values. If the voltage is incorrect, the component might be faulty.
Inspecting Relays
Relays control the flow of electricity. Inspecting them ensures they function properly.
Steps to inspect relays:
- Locate the relay on the control board.
- Use a multimeter to test for continuity.
- If the relay has no continuity, it needs replacement.
Relays should click when activated. If you don’t hear a click, the relay might be defective.
Keep these steps in mind while troubleshooting your Whirlpool refrigerator control board. Proper testing ensures accurate diagnosis and repair.
