Commercial Unit Running Constantly

Why a Commercial Unit Runs Constantly

A commercial refrigeration unit that never cycles off is working harder than normal, and the cause is usually one of four things. A worn door gasket lets warm air leak in continuously, so the compressor never catches up to the thermostat's setpoint and keeps running to compensate. A dirty condenser coil, very common in kitchens where grease and heat collect in the air, reduces the system's ability to reject heat, forcing longer run times to remove the same amount of heat. A refrigerant undercharge means the system has too little refrigerant to cool efficiently, so the compressor runs longer for less cooling effect with every cycle. A thermostat or control board stuck calling for cooling keeps the compressor running even after the cabinet reaches temperature, which wastes energy and shortens the compressor's life. Left unaddressed, constant running raises utility costs and accelerates the wear that leads to compressor failure.

How San Marcos Appliance Repair Fixes It

A technician checks the door gasket, condenser coil, refrigerant charge, and thermostat or control board on-site to find why the unit won't cycle off normally. Catching the cause early costs far less than waiting for the compressor itself to fail from the extra strain. San Marcos Appliance Repair stocks gaskets and control boards for True Manufacturing and Hoshizaki commercial refrigeration and backs every completed repair with a 90-day parts-and-labor warranty. Same-day dispatch is prioritized for commercial accounts because constant running often precedes a full compressor failure. Call 760-621-5157 to schedule a technician today.

Diagnosed by Certified Technicians

Before testing the door gasket, condenser coil, refrigerant charge, and thermostat or control board, the technician assigned to this repair has already completed NASTeC certification in appliance service and repair and an EPA Section 608 certification for refrigerant handling, required for work on this sealed cooling system and trained through MiraCosta College's Technology Career Institute or San Diego College of Continuing Education (SDCCE) under founder and Master Appliance Repair Technician Francisco Ortega, who has run San Marcos Appliance Repair since 2006. Formal certification plus hands-on training backs the 90-day parts-and-labor warranty on every commercial unit running constantly repair, backed by our licensed and insured guarantee.
