Dirty Condenser

  • Z Series

This alarm indicates that your smart equipment has detected a condenser airflow blockage, and as a result, the refrigeration system has been disabled for safety reasons.

Exercise caution when dealing with electrical equipment, as improper handling can result in injury or damage to the equipment. If you are unsure of how to safely troubleshoot the equipment, it is best to seek the assistance of a qualified electrician or technician.

Troubleshooting Steps

The issue could be caused by a few different reasons. Here are a few potential causes and troubleshooting steps you can try:

✨ Pro Tip: Regular cleaning of condenser coils is important to keep your refrigeration system running efficiently. The more frequently you clean the coils, the less likely dirt and debris will become hardened and difficult to remove. We recommend adding a maintenance task in VersaHub, which will allow you to set a reminder and keep track of the status and costs of the repair.

What you'll need

 

  1. Begin by turning off the power to the refrigeration unit. It is important to unplug the unit or shut off power at the breaker to prevent the risk of electrical shock.
  2. Locate the condenser, which is typically located on the outside of the refrigeration unit. It may be covered by a protective grille.
  3. Clean the condenser coils using a soft brush or a vacuum cleaner with a brush attachment to gently remove any dirt or debris that has accumulated on the coils. Be careful not to bend or damage the coils while cleaning, and then apply Noble Chemical Foaming Heavy-Duty Condenser Coil Cleaner.
  4. Check and clean the condenser compressor. After cleaning the coils, it is important to check the compressor and clean it of any debris or dust that has accumulated on it.
  5. Check the condenser fan. Make sure that the fan is free of debris and that it is able to spin freely. If the fan is dirty or clogged, clean it off or remove any debris that may be preventing it from functioning properly.
  6. Inspect the condenser's airflow. Make sure that there is adequate airflow around the condenser. The unit should have at least 6 inches of clearance on all sides to allow for proper airflow. If the unit is blocked or has insufficient airflow, move it to a location where it can receive more air.
  7. Re-connect power, turn on the refrigeration unit, and run the system to see if the dirty condenser problem has been resolved.
  8. If the condenser coils or fan continue to have issues, or if the refrigeration unit is not running properly after cleaning, it may be necessary to contact a repair technician or the manufacturer for further assistance. We recommend adding a maintenance task to VersaHub, which will allow you to set a reminder and keep track of the status and costs of the repair.
