Commercial Steamers, Combi Ovens, and Advanced Electronic Controls

This course prepares commercial equipment technicians to install, diagnose, and maintain atmospheric and pressurized steam cooking platforms as well as combination convection-steam ovens. Technicians analyze water quality dynamics, scale prevention technologies, steam generation assemblies, injection systems, and precise humidity control circuits. The curriculum emphasizes digital electronics, detailing microcontroller architecture, sensor networks, solid-state switching, and communication bus diagnostics utilized in automated food production equipment. Learners develop field-ready competencies in decoding error codes, interpreting complex schematic wiring diagrams, calibrating temperature and humidity sensors, and servicing electro-mechanical venting assemblies. Emphasizing safety and factory-grade diagnostic procedures, students practice systematic fault isolation on live training systems to resolve complex component-level failures. Through intensive hands-on lab sessions and simulated commercial kitchen service calls, participants build the necessary technical confidence to troubleshoot sophisticated electronic cooking controls, multi-stage cooking sequences, and integrated boiler systems efficiently.
