Commercial Refrigeration Compressor Failure

Why Commercial Refrigeration Compressors Fail

Commercial refrigeration compressors run far more hours per year than a residential unit ever does, and that duty cycle is the biggest reason they eventually fail. Years of continuous cycling wear the internal components until the compressor stops pumping refrigerant, regardless of brand. An electrical failure in the start relay can prevent a mechanically sound compressor from starting at all, so the unit hums or clicks without ever running. A refrigerant leak elsewhere in the system forces the compressor to run constantly while pumping too little refrigerant to actually cool, which overheats and eventually burns out the compressor windings. A blocked condenser coil raises head pressure and operating temperature every time the compressor runs, shortening its life the same way a car engine wears faster when it overheats. Because a down compressor means a down unit, this failure is the one commercial kitchens fear most.

How San Marcos Appliance Repair Fixes It

A technician tests the compressor, start relay, refrigerant charge, and condenser on-site to determine whether the compressor itself failed or something else is causing it to fail prematurely. Replacing a compressor is a bigger repair than most, so the technician confirms the diagnosis with pressure and amperage readings before recommending it. San Marcos Appliance Repair stocks compressors and start relays for True Manufacturing and Hoshizaki commercial units and backs every completed repair with a 90-day parts-and-labor warranty. Same-day dispatch is prioritized for commercial and institutional accounts because a compressor failure stops cooling entirely. Call 760-621-5157 to schedule a technician today.

Diagnosed by Certified Technicians

A technician evaluating the compressor, start relay, refrigerant charge, and condenser coil on this repair holds NASTeC certification in appliance service and repair and an EPA Section 608 certification for refrigerant handling, required for work on this sealed cooling system, trained through MiraCosta College's Technology Career Institute or San Diego College of Continuing Education (SDCCE) before joining the team led by founder and Master Appliance Repair Technician Francisco Ortega, who has run San Marcos Appliance Repair since 2006. That training is what backs the 90-day parts-and-labor warranty on every commercial refrigeration compressor failure repair, backed by our licensed and insured guarantee.
