Mojgar 550 LBS Commercial Ice Maker Troubleshooting Guide

The Mojgar 550 LBS Commercial Ice Maker is an efficient and durable machine designed to handle high-volume ice production. Although it performs reliably, like any machine, occasional issues may arise. This guide provides detailed troubleshooting steps for common faults, error codes, and solutions to help you quickly resolve problems and keep your unit running smoothly.

Common Issues and Troubleshooting

1. Ice Maker Won't Start

• Possible Causes:
  • The power is not connected, or the plug is loose.
  • Power cord or outlet issue.
• Solution:
  • Check Power Connection: Ensure the power plug is properly inserted, and the power switch is turned on. If the display is active, the unit is powered.
  • Check Outlet: Test the outlet by plugging in another device to ensure it's working properly.
  • Check Power Cord: Inspect the power cord for visible damage or wear.

2. Ice Full Indicator Light On

• Possible Cause:
  • The ice bucket is full, and the sensor has triggered the "Ice Full" warning.
• Solution:
  • Check Ice Bucket: Ensure that the ice bucket is not overflowing. If it is, remove some ice to resume production.
  • Check Ice Full Sensor: The sensor might be blocked by ice buildup or dirt, clean it thoroughly.

3. Ice Maker Not Producing Ice

• Possible Causes:
  • Water supply issue or incorrect valve connections.
  • Refrigeration system malfunction.
• Solution:
  • Check Water Supply: Ensure the water supply is connected properly and water pressure is sufficient. Check for blockages in the water line.
  • Check Water Inlet Valve: Ensure that the valve is functioning properly and connected correctly.
  • Check Refrigeration System: If cooling is not occurring, the refrigeration system might be faulty. Contact a technician for assistance.

Fault Code Troubleshooting

1. E1 – Water Sensor Failure

• Possible Cause:
  • The water sensor is malfunctioning and unable to detect the water level properly.
• Solution:
  • Check Water Sensor Connection: Ensure the water sensor is securely connected and not loose.
  • Clean the Water Sensor: Remove any dirt or mineral buildup that could be obstructing the sensor.
  • Replace the Water Sensor: If the sensor is damaged, replace it with a new one.

2. E2 – Water Temperature Sensor Failure

• Possible Cause:
  • The water temperature sensor is malfunctioning, leading to inaccurate readings.
• Solution:
  • Check Sensor Connection: Ensure the water temperature sensor is connected securely.
  • Check Water Temperature: Make sure the water temperature is within the recommended range for optimal ice production.
  • Clean the Sensor: Clean any dirt or buildup on the sensor to ensure accurate readings.
  • Replace the Sensor: If the sensor cannot be fixed, replace it.

3. E3 – Ice Thickness Sensor Failure

• Possible Cause:
  • The ice thickness sensor is malfunctioning, preventing proper ice thickness adjustments.
• Solution:
  • Check the Sensor Connection: Ensure the ice thickness sensor is connected properly.
  • Clean the Sensor: Ice buildup or dirt might be blocking the sensor. Clean it thoroughly.
  • Replace the Sensor: If the sensor is faulty or not responding, replace it.

4. E4 – Compressor Overheating

• Possible Cause:
  • Compressor overheating due to poor airflow or refrigeration system malfunction.
• Solution:
  • Check Airflow: Ensure there are no obstructions around the compressor and that airflow is not restricted.
  • Clean the Condenser: Ensure that the condenser is free of dirt and debris for proper cooling.
  • Check Power Supply: Ensure the compressor is receiving the correct power.
  • Replace Compressor: If overheating continues, consider replacing the compressor.

5. E5 – High Pressure Error

• Possible Cause:
  • The refrigeration system has a high-pressure issue, likely due to a malfunctioning valve or overcharged refrigerant.
• Solution:
  • Check the Refrigeration System: Inspect for blockages or faulty valves in the system.
  • Check Refrigerant Levels: Ensure the refrigerant is at the correct level—too much or too little can cause pressure issues.
  • Contact a Technician: If the problem persists, contact a professional technician to inspect and fix the issue.
