Step-by-Step Troubleshooting Guide
- Identify the Error Code
Check the display on your thermostat or furnace. Note down the error code for reference. - Turn Off the Power
Ensure safety first. Switch off the power to your furnace at the circuit breaker. - Inspect the Air Filter
A dirty filter can restrict airflow. Replace or clean the filter if it appears clogged. - Examine the Vents
