Commercial fridges play a crucial role in the food service industry, ensuring the freshness and safety of perishable items. When a commercial fridge breaks down, it can lead to significant inconvenience and financial losses for businesses. While professional assistance is often required for complex issues, you can take several simple steps to troubleshoot and repair minor problems with your commercial fridge.

This article presents a comprehensive guide with ten easy steps to help you repair your commercial fridge in London. By following these steps, you can save time and money by resolving common issues yourself.

Steps to Repair Your Commercial Fridge

Check the Power Supply

The first and simplest step when your commercial fridge stops working is to verify the power supply. Ensure that the fridge is properly plugged into a functioning power outlet. Check the circuit breaker or fuse box to ensure no tripped breakers or blown fuses. If the power supply seems fine, move on to the next step.

Examine the Temperature Settings

Incorrect temperature settings can cause your commercial fridge to malfunction. Check the thermostat and ensure it is set to the desired temperature. Avoid setting it too high or too low, as this can lead to cooling problems. Additionally, check if the evaporator fan is working correctly. If the fan is not running, it may need to be replaced or repaired by a professional.

Clean the Condenser Coils

Dirty condenser coils can impede the cooling efficiency of your commercial fridge. Locate the condenser coils, typically at the back or bottom of the unit, and inspect them for dirt, dust, or debris. Use a soft brush or vacuum cleaner to remove any buildup gently. Cleaning the coils regularly can improve the fridge’s performance and prevent potential breakdowns.

Check the Door Seals

Faulty door seals can cause air leakage, leading to temperature inconsistencies and increased energy consumption. Inspect the door gaskets for any signs of damage or wear. If you notice cracks, gaps, or loose seals, they may need to be replaced. Ensure the doors close tightly by applying slight pressure and checking for resistance. Adjust or replace the door seals as necessary.

Verify the Defrost System

If your commercial fridge has a built-in defrost system, it is crucial to ensure it functions properly. Check the defrost timer, heater, and defrost thermostat for any faults. If you suspect a problem with the defrost system, consult the fridge’s user manual or contact a professional technician for assistance. Neglecting the defrost system can result in ice buildup, obstructed airflow, and compromised cooling performance.

Inspect the Evaporator Fan Motor

A malfunctioning evaporator fan motor can disrupt cold air circulation inside the fridge. Listen for unusual noises from the motor, which may indicate a problem. If the fan is not running or not operating smoothly, it may need lubrication or replacement. Cleaning accumulated debris from the fan blades can also help improve its performance.

Assess the Compressor

The compressor is the heart of your commercial fridge, responsible for maintaining the desired temperature. Check for any signs of damage, leaks, or excessive vibrations. If you suspect a problem with the compressor, it is recommended to seek professional assistance, as repairs or replacements require specialized knowledge and tools.

Maintain Proper Airflow

Ensure that the vents and air circulation pathways inside the fridge are unobstructed. Rearrange items if necessary to promote proper airflow. Avoid overpacking the fridge, as overcrowding can restrict airflow and lead to temperature imbalances. Regularly cleaning the fridge’s interior and removing accumulated debris can improve airflow.

Test the Door Switches and Lights

Faulty door switches can prevent the interior lights from turning on or off properly and can also affect the cooling function. Open and close the fridge doors while observing the lights. If the lights fail to turn on or off consistently, the door switches may require adjustment or replacement.

Contact a Professional Technician

If you have followed the previous steps and your commercial fridge still fails to operate correctly, it is advisable to contact a professional technician. They possess the expertise, experience, and necessary equipment to diagnose and repair complex issues. Attempting to repair advanced problems without professional knowledge may worsen the situation and lead to higher repair costs.


Following these ten easy steps, you can troubleshoot and repair minor issues with your commercial fridge in London. Regular maintenance, proper cleaning, and prompt attention to any problems can extend the lifespan of your fridge and prevent costly breakdowns. Remember, while these steps can resolve simple issues, more complex repairs should be handled by trained professionals. Safeguard your investment in commercial refrigeration equipment by staying proactive and ensuring your fridge operates efficiently, promoting the freshness and safety of your perishable inventory.
