Common Commercial Reach-In Refrigerator Problems We Fix
Unit Not Cooling
The most urgent commercial refrigeration call we get. If the unit is running but not holding temperature, the most common causes are dirty condenser coils restricting airflow, a failing evaporator fan motor, a defrost system failure, or a refrigerant issue. Our EPA 608 certified technicians handle sealed system diagnostics correctly and fix the actual cause.
Compressor Not Starting
A compressor that clicks and hums but will not start is usually a failed start relay β a component we carry on every truck. If the compressor itself has failed, we will give you an honest assessment of whether repair or replacement makes more sense for your specific unit and operation.
Excessive Frost Buildup
Ice buildup on the evaporator coils almost always points to a defrost system failure β a bad defrost heater, defrost thermostat, or defrost timer. It can also be caused by a door gasket that is not sealing properly. We identify the exact component that has failed and fix it correctly.
Door Gasket Failures
Worn or damaged door gaskets are one of the most common commercial refrigerator issues we see. A bad gasket lets warm air into the unit, forces the compressor to work overtime, raises energy costs, and puts food safety at risk. We carry common gasket sizes on every truck.
Evaporator Fan Not Working
The evaporator fan circulates cold air throughout the unit. When it fails, the unit may still run but temperature distribution becomes uneven and the unit struggles to maintain set temperature. Fan motor replacement is a straightforward repair we complete same visit in most cases.
Condenser Coils Dirty or Clogged
Dirty condenser coils are the number one cause of premature compressor failure in commercial refrigerators. In a kitchen environment, grease and dust clog coils fast. We clean condenser coils on every service call and advise on a regular maintenance schedule to prevent future issues.
Temperature Fluctuations
Inconsistent temperature in a commercial refrigerator is a food safety issue. Usually caused by a faulty thermostat, a failing temperature control board, a defrost system that is running too frequently, or a door that is not sealing properly. We test the full temperature control system and repair the specific cause.
Unit Running Constantly
A commercial refrigerator that never cycles off is working harder than it should and will wear out faster. Usually caused by dirty condenser coils, a failing door gasket, a bad thermostat, or a defrost system issue. We diagnose the root cause and fix it before it leads to a compressor failure.
Water Leaking Inside or Under the Unit
Water pooling inside or underneath a commercial reach-in is usually a clogged defrost drain, a cracked drain pan, or a door seal issue causing excessive condensation. Left unattended it creates slip hazards and can damage flooring. We find the source and fix it fast.
Electrical and Control Board Issues
Modern commercial refrigerators have electronic control boards that manage temperature, defrost cycles, and alarms. When these fail, the unit may behave erratically or shut down entirely. We diagnose control board issues accurately and replace only what is needed.
