Stop the Drip:
Troubleshooting Your Commercial Fridge's Leaks

A commercial fridge is a vital component of any food service establishment, ensuring that perishable goods are stored at the optimal temperature to maintain freshness and safety. However, encountering a leaking commercial fridge can quickly become a cause for concern. Not only does it pose a risk to the integrity of your stored goods, but it can also lead to potential damage to your kitchen floor and equipment. In this blog post, we’ll explore some common reasons why your commercial fridge might be leaking and what you can do to address the issue effectively.

Blocked or Clogged Drain Line:

One of the most common causes of a leaking commercial fridge is a blocked or clogged drain line. Over time, debris, food particles, and mineral deposits can accumulate in the drain line, preventing proper drainage of condensation water. As a result, water may overflow from the drain pan and leak onto the floor.

Solution: To address a blocked drain line, start by locating the drain opening inside the fridge compartment. Use a pipe cleaner or a small brush to remove any debris or build-up from the drain line. You can also flush the drain line with a mixture of warm water and mild detergent to dislodge stubborn clogs. Regular maintenance of the drain line can help prevent future leaks and ensure proper functioning of your commercial fridge.


Faulty Door Gasket:

The door gasket, also known as the door seal, plays a crucial role in maintaining the temperature and humidity levels inside your commercial fridge. If the door gasket is damaged, worn out, or improperly installed, it may fail to create an airtight seal, allowing cold air to escape and warm air to enter. Condensation can then form on the exterior of the fridge, leading to leaks.

Solution: Inspect the door gasket for signs of wear, tears, or damage. If you notice any issues, replace the gasket promptly to ensure a tight seal. Clean the gasket regularly with warm, soapy water to remove dirt and debris that could compromise its effectiveness. Properly align the gasket with the door frame to ensure a snug fit and prevent air leaks.


Excessive Frost Build-up:

If your commercial fridge experiences excessive frost build-up on the evaporator coils, it can lead to leaks when the frost melts. This can occur due to factors such as frequent door openings, a malfunctioning defrost timer, or inadequate airflow within the fridge.

Solution: Check the defrost timer and thermostat to ensure they are functioning correctly. If necessary, adjust the defrost settings to prevent excessive frost accumulation. Regularly defrost your commercial fridge according to the manufacturer’s recommendations to prevent frost build-up. Ensure proper airflow by arranging items inside the fridge to allow for adequate circulation.


Damaged or Defective Drain Pan:

The drain pan is located beneath the evaporator coils and is designed to collect condensation water that drips down from the coils during the cooling process. If the drain pan is cracked, rusted, or improperly positioned, it may fail to contain the collected water, resulting in leaks.

Solution: Inspect the drain pan for any signs of damage or deterioration. If the drain pan is damaged, replace it with a new one to ensure proper containment of condensation water. Clean the drain pan regularly to remove any debris or build-up that could interfere with its function. Ensure that the drain pan is securely positioned and level to prevent water from spilling out.


Refrigerant Leak:

In rare cases, a leaking commercial fridge may be caused by a refrigerant leak. Refrigerant leaks can occur due to factors such as corrosion, physical damage to the refrigerant lines, or faulty components within the refrigeration system. If you suspect a refrigerant leak, it’s essential to address the issue promptly to prevent further damage to your fridge and ensure the safety of your stored goods.

Solution: If you suspect a refrigerant leak, contact a qualified refrigeration technician to inspect and repair the issue. Refrigerant leaks pose potential health risks and should be handled by trained professionals with the necessary equipment and expertise to safely identify and repair the leak. Avoid attempting to repair a refrigerant leak yourself, as improper handling of refrigerants can have serious consequences.

A leaking commercial fridge can be a frustrating and potentially costly issue for any food service establishment. By identifying the underlying cause of the leak and taking prompt action to address it, you can prevent further damage to your fridge, protect your stored goods, and maintain a safe and hygienic kitchen environment. Regular maintenance and inspection of your commercial fridge can help prevent leaks and ensure the continued reliability and performance of your refrigeration system. If you encounter persistent or severe leaks, don’t hesitate to seek professional assistance to resolve the issue effectively.
