Conduct comprehensive cleaning and sanitization of ice machines, storage bins, and dispensers in strict accordance with public health regulations and food safety standards (e.g., HACCP).
Meticulously monitor, maintain, and replace water filtration systems and cartridges to guarantee high water quality and prevent scale buildup that can damage machinery.
Calibrate machine settings to optimize ice production volume, cube clarity and size, and energy efficiency based on operational demands and manufacturer specifications.
Respond promptly and effectively to urgent, unscheduled service calls for malfunctioning or broken-down ice machines to minimize operational downtime for clients or facilities.
Confidently read and interpret complex electrical schematics, wiring diagrams, and detailed technical manuals to guide troubleshooting and repair processes.
Maintain a precise and organized inventory of spare parts, specialized tools, and essential supplies, and process orders for new components as needed.
Diligently document all service activities, including repairs performed, parts used, and time spent, within a computerized maintenance management system (CMMS) or service log.
Perform refrigerant recovery, system evacuation, and precise recharging of refrigeration systems in full compliance with federal EPA Section 608 regulations.
Test, diagnose, and replace faulty refrigeration components, including thermostats, solenoid valves, pressure controls, and expansion valves.
Ensure all work is performed in a consistently safe manner, rigorously adhering to company safety policies, OSHA standards, and proper lockout/tagout (LOTO) procedures.
Provide clear, concise, and professional communication to managers, colleagues, or clients regarding the status of repairs, required parts, and estimated completion timelines.
Skillfully install new ice machine units, which includes running water lines, installing proper drainage, and making final electrical connections according to code.
Train end-users, such as kitchen staff or facility employees, on the basic daily operation, cleaning procedures, and simple troubleshooting for their ice machines.
Conduct regular, thorough inspections of ice machine performance, proactively checking for water or refrigerant leaks, unusual noises, and temperature inconsistencies.
Identify and recommend opportunities for improving machine efficiency, suggesting equipment upgrades, retrofits, or replacements to enhance reliability and reduce costs.
Effectively manage and prioritize a daily or weekly queue of work orders to ensure the timely and efficient completion of all assigned maintenance and repair tasks.
Safely handle and transport heavy equipment and components using appropriate lifting techniques, dollies, and other material handling equipment.
Verify the proper operation of the entire ice-making cycle, from the initial water fill and freeze cycle to the final harvest and storage of ice.
Address and resolve a variety of plumbing-related issues connected to the ice machines, such as inadequate water pressure, flow rates, and clogged drain lines.

Secondary Functions

Assist other maintenance technicians with general facility or commercial kitchen equipment repairs as directed, fostering a collaborative team environment.
Actively participate in departmental safety meetings and contribute practical suggestions for improving workplace safety protocols and procedures.
Support the broader maintenance department with inventory management, tool organization, and maintaining the cleanliness of the workshop and service vehicles.
