About the Course:

This Diagnosing and Replacing Ignitors microcredential trains HVAC technicians to safely diagnose, remove, and replace faulty furnace ignitors in gas heating systems. Enroll in our Professional HVAC Course to gain broader HVAC skills and hands-on training.

Learning Objectives:

  • Identify symptoms of ignitor failure, including lack of glow despite proper voltage supply.

  • Safely shut down and power up furnaces during diagnostic procedures.
  • Use a multimeter to measure voltage at the ignitor connection.
  • Confirm ignitor failure through voltage verification.
  • Remove faulty ignitors using proper tools and safety practices.
  • Install and secure replacement ignitors correctly.
  • Verify restored furnace ignition and system operation

Course delivered via LMS and requires an Oculus VR headset for hands-on VR simulations.

Workforce Development

Hands-on HVAC training replacing faulty furnace ignitors accurately

At ImmerseLearn, we equip HVAC technicians with hands-on, job-ready skills for servicing gas heating systems. This microcredential strengthens diagnostic precision, electrical safety awareness, and component replacement accuracy through immersive VR practice.  

How this course strengthens workforce skills:

Ignitor Diagnostics −
Learn how to diagnose ignitor failures by confirming power delivery and recognizing non-functioning components, even when proper voltage is present. This skill helps technicians avoid unnecessary part replacements and reduce system downtime.
Safe Shutdown and Testing Procedures +
Practice critical safety steps including shutting down the gas furnace, unplugging components, and re-energizing the system for controlled diagnostics. Emphasis is placed on safe sequencing to prevent injury or equipment damage.
Cause Identification +
Determine common causes of ignitor failure such as age-related wear, electrical stress, or thermal damage by interpreting test results and system behavior.
Replacement and Verification +
Select and install a compatible replacement ignitor, secure it correctly, and verify proper furnace operation. Learners complete the process by confirming successful ignition and safe system performance.

By completing this microcredential, HVAC technicians will build the confidence and technical skills needed to diagnose ignitor failures, replace components safely, and restore reliable furnace operation in real-world service environments.
