Igloo Ice Maker Not Working: How to Troubleshoot

If you’re facing issues with your igloo ice maker not working, you’re not alone. Ice makers are intricate machines with various components, and when something goes wrong, it can be challenging to pinpoint the root cause.

Here, we’ll find the problems and their solutions of the Igloo ice maker, where there areare symptoms of different component failures.

Highlights:

• Ensure both side and top switches move freely to avoid tray cycling and water-related issues.
• A solid “Add Water” light indicates potential water sensor failure; inspect the water supply and sensor for problems.
• Regularly check fan RPM and secure the thermistor to prevent larger-than-usual ice cubes.
• Verify the solenoid valve’s functionality to ensure proper ice release and prevent freeze-ups.
• If no ice is produced, assess the compressor’s operation and consider replacement if needed.

How to Troubleshoot Igloo Ice Maker Not Working

To troubleshoot an Igloo ice maker not working, check for stuck switches, ensure proper water flow and sensor functionality, inspect the fan and thermistor, and address potential issues with the solenoid valve or compressor.

Join us as we explore the troubleshooting steps for common problems that may be hindering your ice maker’s performance.

1. Side Switch: Stuck in the Pressed Position

• Symptoms: The ice tray cycles without filling with water.
• Additional Observations: After 15-20 minutes, the “Add Water” and “Ice Full” lights flash alternately.
• Potential Solution: Examine the side switch for any sticking. If found, release the switch to allow the tray to cycle properly.

2. Top Switch: Tray Stays in Dumped Position

• Symptoms: The tray remains in the dumped position; prongs inside get frosty.
• Additional Observations: No flashing red lights observed during this issue.
• Potential Solution: Investigate the top switch for any abnormalities. If stuck, release the switch to restore normal operation.

3. Water Pump Failure

• Symptoms: The ice tray cycles normally, but no water fills the tray; “Solid” and “Water” lights are on.
• Potential Solution: Diagnose the water pump for any malfunctions. If the pump is faulty, consider replacing it to restore water flow and ice production.

4. Fan Failure

• Symptoms: Initially normal operation, but over time, reduced ice production leading to smaller or no ice.
• Potential Solution: Inspect the fan for any signs of failure. If the fan stops working, replacing it is crucial to maintain optimal ice production.

5. Thermistor Issues

• Symptoms: Larger ice produced even on the small ice setting.
• Additional Observations: If the thermistor comes out of its housing, the ice maker behaves as if the fan isn’t working.
• Potential Solution: Ensure the thermistor is securely in its housing. A well-seated thermistor is essential for regulating temperature and preventing oversized ice.

6. Electromagnet (Back of the Machine)

• Symptoms: Failure leads to ice not dropping, causing freeze-ups and solid blocks of ice.
• Potential Solution: Inspect the electromagnet for any issues. If it’s not functioning, consider replacing it to allow the ice to drop as intended.

7. Compressor Failure

• Symptoms: The tray functions normally, water pumps, but no ice is produced due to compressor failure.
• Additional Observations: No red lights indicate the issue.
• Potential Solution: When the compressor fails, replacement becomes necessary to restore the cooling system’s functionality and ice production.

8. Diode Check for Ice Full Light Issues

• Procedure: Use a digital camera to check if the infrared emitter and receiver diodes are operational.
• Symptoms: Continuous Ice Full light issues if diodes are not working.
• Workaround: Hold the selector button for 10-15 seconds to reset the cycle if diodes are malfunctioning and affecting the Ice Full light.

Additional Tips

• When replacing the thermistor, avoid pulling the plug off the board as it is soldered. Seek professional assistance if needed.
• If facing persistent “Ice Full” light issues, check the diodes in the infrared sensor. Use a digital camera to verify the emitter and receiver diodes are functioning. If not, press and hold the selector button for 10-15 seconds as a temporary workaround.

Conclusion

Troubleshooting an Igloo ice maker can be a meticulous process, requiring attention to various components. Identifying the specific issue can help you take the necessary steps to restore your ice maker’s functionality.

Remember to exercise caution and seek professional assistance if you’re unsure about any repairs. Following these troubleshooting steps, you can enjoy a frosty, problem-free ice-making experience.
