Safety Information
WARNING: Installation and servicing of HVAC components should only be performed by qualified, trained, and experienced technicians. Improper installation, adjustment, alteration, service, or maintenance can cause property damage, personal injury, or loss of life. Always disconnect power to the furnace before attempting any installation or service.
- Ensure the main power supply to the furnace is disconnected before beginning any work.
- Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Handle the ignitor carefully; silicon-nitride can be fragile.
- Verify correct voltage and wiring connections as per the furnace manufacturer's specifications.
- Do not bypass any safety controls.
Setup and Installation
The ADX080C942D3 ignitor is designed as a direct OEM replacement. It comes with a bracket and screws for proper mounting. Refer to the specific installation guide included with the product and your furnace's service manual for detailed, step-by-step instructions.
- Power Disconnection: Turn off all electrical power to the furnace at the main service panel.
- Access: Open the furnace access panel to locate the existing ignitor.
- Removal of Old Ignitor: Carefully disconnect the wiring and unmount the old ignitor. Note its orientation and mounting position.
- Mounting New Ignitor: Use the provided bracket and screws to mount the new ADX080C942D3 ignitor in the same position and orientation as the original. Ensure it is securely fastened.
- Wiring Connection: Connect the ignitor's wiring harness to the furnace's control board or designated ignitor connector. Ensure connections are secure and correct.
- Verification: Double-check all connections and ensure no wires are pinched or exposed.
- Restore Power: Close the furnace access panel and restore electrical power.
- Test Operation: Initiate a heating cycle to confirm proper ignition and furnace operation.

Operating Principle
The hot surface ignitor functions as an electronic ignition device for gas furnaces. When a call for heat is initiated, the ignitor receives electrical current, causing its silicon-nitride element to heat up rapidly to a very high temperature. This glowing hot surface then ignites the gas flowing into the burner. Once the flame is established and sensed by the furnace's flame sensor, the ignitor's power is typically cycled off until the next heating cycle.
Maintenance
Hot surface ignitors are wear-and-tear components and generally do not require routine user maintenance. However, regular professional inspection of your furnace system is recommended. During these inspections, a qualified technician can:
- Inspect the ignitor for signs of cracking, discoloration, or damage.
- Check electrical connections for corrosion or looseness.
- Ensure proper alignment and positioning within the burner assembly.
If the ignitor shows signs of wear or damage, it should be replaced by a qualified technician to ensure safe and efficient furnace operation.
Troubleshooting
If your furnace is not igniting or experiencing intermittent ignition, the hot surface ignitor may be a contributing factor. Common symptoms of an ignitor issue include:
- Furnace cycles on, but no flame appears, and the ignitor does not glow.
- Ignitor glows but fails to ignite the gas.
- Ignitor glows intermittently or weakly.
Important: Troubleshooting furnace components, especially those involving gas and high voltage, should only be performed by a certified HVAC technician. Attempting repairs without proper training and tools can be dangerous and may void your furnace's warranty.
A technician will typically check for:
- Proper voltage supply to the ignitor.
- Continuity of the ignitor element.
- Correct wiring and connections.
- Other furnace components that might affect ignition, such as the gas valve or control board.
