Leaking Commercial Refrigerator? Common Causes and Fixes

If you’re searching for Appliance Repair San Marcos because your commercial refrigerator is leaking, you’re not alone. Water on the floor or inside the fridge is a common issue that signals something isn’t working right. While it may look minor, a leak can point to bigger problems if left unchecked.

Technicians who specialize in Appliance Repair San Marcos often trace fridge leaks to a few key causes. The most common is a clogged or frozen drain line. Commercial refrigerators use a drain system to move condensation out of the unit. When the line gets blocked by dirt, ice, or debris, water backs up and starts to pool inside or underneath the fridge.

Another frequent cause is a broken or loose drain pan. The pan sits underneath the fridge and collects water from the drain line. If it’s cracked or out of place, water spills directly onto the floor. Some pans can be easily adjusted or replaced, but ignoring the issue leads to puddles and possible mold growth.

Door gasket problems can also cause leaks. If the seal around the door is torn or no longer sealing tightly, warm air sneaks in and creates excess condensation. That moisture builds up and ends up as water around the base of the unit. Checking and replacing faulty gaskets is a quick fix that helps keep humidity under control.

A misaligned or blocked defrost system is another potential problem. If the defrost heater doesn’t activate properly, ice can build up inside the evaporator coils and eventually melt all at once. This sudden release of water overwhelms the drain system and causes leaks. A technician can inspect the timer, heater, and sensors to fix the cycle.

In some cases, poor leveling is to blame. Commercial fridges must be slightly tilted back so water flows naturally into the drain. If the fridge sits too flat or tilted forward, water may not drain properly. Adjusting the unit’s feet can solve the problem without any part replacement.

Leaking can also come from internal components like cracked water lines or loose hose connections in models that include automatic defrost or water dispensers. These leaks are harder to spot but often more serious. If water is leaking from the back of the unit, it’s best to call in a pro quickly.

Ignoring a leak isn’t worth the risk. Even small puddles can damage flooring, increase slip hazards, and lead to health code violations. If your team notices water under or around the fridge, don’t wait. Regular cleaning and visual checks can catch most of these issues early.

To avoid recurring problems, schedule preventive maintenance twice a year. Professionals from Appliance Repair San Marcos can clean the drain system, check seals, and confirm the unit is level and running correctly. Fixing a leak early keeps your fridge working, your floor dry, and your business safe.
