A fireplace service technician diagnoses and repairs appliances across every fuel type — gas, electric, wood, and pellet — which means the job is fundamentally about systematic troubleshooting, not memorizing one product line. The technicians who last in this trade are the ones who can walk into an unfamiliar model, isolate the actual failure with test equipment instead of guesswork, and fix the real problem the first visit instead of the symptom.

This course covers the test equipment and safety discipline you need before you touch a live gas or electrical system, the combustion and airflow fundamentals that explain why appliances fail the way they do, ignition and control systems across fuel types, and a genuine troubleshooting methodology — not a flowchart to memorize, but a way of thinking that generalizes to a model you’ve never serviced before.
