Duke Commercial Ovens & Stove Repair in Jacksonville Beach

Duke Manufacturing, founded in 1925 in St. Louis, Missouri, manufactures a broad line of commercial cooking and food-holding equipment including heated holding cabinets, subway-style sandwich units, steam tables, convection ovens, electric ranges, fryers, and proofer cabinets used in restaurants, schools, hospitals, and large chain foodservice operations across North America. Duke is best known for its heated holding cabinets used by major QSR chains and its line of Subway-style food-prep refrigeration and heated units. The brand also supplies cafeteria and serving-line equipment to school districts, healthcare systems, and institutional operators. Duke equipment is engineered for high-volume, long-life service in environments where temperature control and durability are non-negotiable.

We have serviced Duke heated holding cabinets, steam tables, convection ovens, range tops, and sandwich-prep units for over ten years in QSR chains, schools, hospitals, and restaurants. Our technicians know the tubular holding elements, low-water cutoff sensors, solid-state thermostats, range burner valves, conveyor belt systems, and door gasket assemblies from hands-on field work. We stock OEM Duke elements, thermostats, low-water sensors, valves, gaskets, fan motors, and conveyor belts for same-day repairs.

Service begins with a diagnostic: we check element resistance, verify thermostat response against a calibrated reference probe, test low-water cutoff function on steam tables, inspect the door gasket seal, and check conveyor speed where applicable. After identifying the root cause we source the correct OEM Duke part — element, thermostat, sensor, gasket, valve, fan motor, or belt — and install it to documented specs. Final calibration includes temperature uniformity verification, food-safe holding range check, and a full cycle test. Every repair closes with a written report, parts list, and a 90-day warranty.
