Installation (Setup)
This procedure requires basic electrical and mechanical skills. If you are unsure, consult a qualified HVAC technician.
- Power Disconnection: Locate the furnace's electrical disconnect switch and turn off all power to the unit. Additionally, turn off the gas supply to the furnace.
- Access Igniter: Open the furnace access panel to locate the existing igniter. It is typically found near the burner assembly.
- Remove Old Igniter: Carefully disconnect the electrical wires from the old igniter. Note their orientation for proper re-connection. Unscrew any mounting hardware holding the old igniter in place and remove it.
- Inspect Area: Clean any debris or carbon buildup from the igniter mounting area.
- Install New Igniter: Mount the new ClimaTek igniter using the provided mounting bracket and screws. Ensure it is securely fastened and positioned correctly according to your furnace's specifications. Avoid overtightening.
- Connect Wiring: Connect the new igniter's wires to the furnace wiring. Use the provided ceramic wire nuts to ensure secure and insulated connections. Double-check that the connections match the original wiring configuration.
- Secure Access Panel: Close and secure the furnace access panel.
- Restore Power and Gas: Turn on the gas supply to the furnace, then restore electrical power.
- Test Operation: Initiate a heating cycle on your thermostat to test the furnace's operation. Observe the igniter to ensure it glows and ignites the gas burners properly.
Operation
The furnace igniter is a critical component in modern gas furnaces. When a call for heat is initiated by the thermostat, the igniter receives electrical current and heats up to a very high temperature, glowing red. This hot surface then ignites the gas flowing from the burners. Once the gas is ignited, a flame sensor confirms the presence of a flame, and the igniter typically deactivates until the next heating cycle. The ClimaTek igniter functions identically to the original equipment it replaces, ensuring reliable furnace startup.
Maintenance
The ClimaTek furnace igniter is a sealed component and does not require routine maintenance. Its lifespan is primarily determined by usage and environmental factors within the furnace. To ensure optimal performance and longevity of your furnace system, it is recommended to:
- Schedule annual professional furnace inspections and servicing.
- Ensure proper airflow by regularly changing or cleaning furnace filters.
- Keep the area around the furnace clear of obstructions and combustible materials.
If the igniter appears cracked, discolored, or fails to glow during a heating cycle, it likely requires replacement.
Troubleshooting
If your furnace is not operating correctly after igniter replacement, consider the following common issues:
| Problem | Possible Cause | Solution |
|---|---|---|
| Furnace does not start, igniter does not glow. | No power to furnace, faulty wiring connection, igniter failure (unlikely if new). | Check circuit breaker. Verify all electrical connections are secure. Ensure furnace access panel is closed properly. |
| Igniter glows, but gas does not ignite. | Gas supply off, faulty gas valve, dirty burners, flame sensor issue. | Ensure gas supply valve is open. Check for obstructions in burner ports. Inspect flame sensor for dirt or damage. |
| Igniter glows, gas ignites, but furnace cycles off quickly. | Flame sensor not detecting flame, restricted airflow, dirty filter. | Clean or replace furnace filter. Clean flame sensor. Ensure all vents are open. |
If troubleshooting steps do not resolve the issue, it is recommended to contact a qualified HVAC technician for further diagnosis and repair.
