Overview

An Electronic Automatic Boiler Controls Maintenance Technician maintains automatic boiler controls, steam plant controls, combustion monitoring equipment, and boiler ignitor systems. The technician performs preventive and corrective maintenance, troubleshooting, calibration, and testing on system and subsystem components.

Core Skills

  • Steam plant control troubleshooting and calibration
  • Boiler combustion monitoring system maintenance
  • Boiler ignitor system testing and repair

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Troubleshooting, calibrating, testing, and repairing electronic boiler and steam plant controls transfers directly to industrial electronic equipment diagnostics and maintenance.

How to prepare: Prepare a work sample showing how you diagnosed a control-system fault, selected component tests, completed corrective maintenance, and verified operation.

What the civilian work involves
  • Test faulty equipment to diagnose malfunctions, using test equipment or software, and applying knowledge of the functional operation of electronic units and systems.
  • Maintain equipment logs that record performance problems, repairs, calibrations, or tests.
  • Set up and test industrial equipment to ensure that it functions properly.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS

Stationary Engineers and Boiler Operators

Maintaining boiler controls, combustion monitoring systems, and steam plant controls provides a foundation for recognizing equipment problems and interpreting boiler operating conditions.

How to prepare: Seek supervised boiler-operations training covering water, chemical, and fuel-level monitoring to build beyond controls maintenance. Some state and local jurisdictions require licenses that typically involve experience and a written exam, restrict unsupervised operation by equipment type and size, and may require another examination after relocation.

What the civilian work involves
  • Operate or tend stationary engines, boilers, and auxiliary equipment, such as pumps, compressors, or air-conditioning equipment, to supply and maintain steam or heat for buildings, marine vessels, or pneumatic tools.
  • Analyze problems and take appropriate action to ensure continuous and reliable operation of equipment and systems.
  • Observe and interpret readings on gauges, meters, and charts registering various aspects of boiler operation to ensure that boilers are operating properly.
Civilian tools and software (examples)
  • Building management system software
