When your commercial refrigerator in Hollywood stops cooling, it's more than just an inconvenience – it's a potential disaster for your business. Keeping your perishables at the right temperature is crucial, and a sudden loss of cooling can lead to significant spoilage and lost revenue. This page will help you understand the common reasons why your commercial unit might not be cooling properly, from simple issues you can safely check yourself to more complex problems that require professional attention. We'll guide you through what to look for and when it’s time to call in the experts at RubinPro Appliance Repair to get your system back to optimal performance.
Common causes of commercial refrigerator not cooling
Dirty Condenser Coils
importantCan DIY checkDust and debris on the condenser coils prevent the refrigerator from releasing heat effectively. This makes the compressor work harder and can lead to insufficient cooling.
Faulty Evaporator Fan Motor
criticalPro recommendedThe evaporator fan circulates cold air within the refrigerator compartment. If this motor fails, cold air won't be distributed, causing the unit to warm up.
Thermostat Malfunction
importantPro recommendedThe thermostat controls the temperature inside the refrigerator. If it's not reading the temperature correctly or sending the right signals, the cooling system may not engage when needed.
Door Seal Issues
importantCan DIY checkWorn or damaged door gaskets allow cold air to escape and warm, moist air to enter. This forces the cooling system to run constantly without maintaining the desired temperature.
Refrigerant Leak
criticalPro recommendedA loss of refrigerant means the system cannot transfer heat properly. This is a serious issue that requires professional attention to locate and repair the leak and recharge the system.
Defrost System Failure
importantPro recommendedThe defrost system prevents ice buildup on the evaporator coils. If it fails, ice can accumulate, blocking airflow and reducing cooling efficiency.
Quick checks you can run safely
- 1
Check Door Seals
Inspect the rubber gaskets around the doors for any tears, gaps, or signs of wear. Ensure the doors are closing completely and creating a tight seal.
Safety: Be careful not to pinch fingers when closing doors. - 2
Listen for the Evaporator Fan
Open the refrigerator door and listen carefully. You should hear a fan running inside the freezer or refrigerator compartment. If you don't hear it, the fan might be the issue.
Safety: Be cautious of any moving parts inside the appliance. - 3
Clean Condenser Coils
Locate the condenser coils (usually on the back or underneath). Unplug the refrigerator and carefully clean away any dust or debris using a vacuum cleaner with a brush attachment or a specialized coil brush. Plug the unit back in after cleaning.
Safety: Always unplug the appliance before cleaning coils to prevent electrical shock. Coils may have sharp edges. - 4
Verify Temperature Settings
Double-check that the thermostat is set to the correct temperature. Sometimes settings can be accidentally changed.
- 5
Check for Airflow Obstructions
Ensure that food items are not blocking air vents inside the refrigerator or freezer compartments, as this can impede cold air circulation.
When to call a pro right away
You suspect a refrigerant leak.
Refrigerant is a hazardous substance that requires specialized equipment and certification to handle. Improper handling can be dangerous and illegal.
The compressor is not running, or you hear unusual noises.
These symptoms can indicate serious mechanical or electrical problems with the core components of the cooling system, requiring professional diagnosis and repair.
The unit is not cooling at all, and basic checks haven't resolved the issue.
A complete loss of cooling often points to a failure in a critical component like the fan motor, thermostat, or sealed system, which needs expert attention.
You notice signs of electrical issues, such as sparking, burning smells, or tripped breakers.
Electrical problems pose a significant risk of fire and electrocution and should only be handled by qualified technicians.

How our repair process works
Five steps from your first call to the warranty receipt. No surprises.
- 1
Inspection
Your technician examines the appliance, listens to your description, and notes the model + serial for parts lookup. Visual + audio-based diagnostics first — non-invasive.
- 2
Diagnostics
Targeted tests on the failing subsystem (compressor, control board, heating element, motor, etc.) to identify the exact root cause. You get a clear explanation, not jargon.
- 3
Fix decision
Up-front estimate before any work begins: cost, parts, and the realistic likelihood of success vs. recommending replacement on an old or uneconomical unit. You decide.
- 4
Operational test
After the repair we run the appliance through its normal cycle on-site — never "it should work now, call us if it doesn't." You sign off when it's actually working.
- 5
Warranty + consultation
Receipt with warranty terms in writing. Plus a quick walkthrough of how to extend the appliance's life (filter cleaning, drain maintenance, etc.) — included free.
