3. Safety Information

WARNING: Improper installation, adjustment, alteration, service, or maintenance can cause property damage, personal injury, or loss of life. Read and understand all instructions thoroughly before proceeding. Installation and service must be performed by a qualified installer, service agency, or gas supplier.

• Electrical Hazard: Always disconnect all electrical power to the furnace unit before installing or servicing the ignitor. Failure to do so can result in electric shock, severe injury, or death.
• Burn Hazard: Furnace components can be hot. Allow sufficient time for the furnace to cool before handling any parts.
• Gas Leak Hazard: Ensure all gas connections are secure and leak-free after any service involving gas components.
• Fragile Component: Hot surface ignitors are made of ceramic material and are fragile. Handle with extreme care to prevent breakage.

4. Setup and Installation

This ignitor is designed for direct replacement in compatible American Standard and Trane furnace models. Refer to your specific furnace's service manual for detailed instructions and safety precautions.

General Installation Steps:

1. Disconnect Power: Turn off the electrical power to the furnace at the main service panel. Verify power is off using a voltage tester.
2. Access Ignitor: Locate and open the furnace access panel to expose the burner assembly and existing ignitor.
3. Disconnect Wiring: Carefully disconnect the electrical wires from the old ignitor. Note the wiring configuration if necessary.
4. Remove Old Ignitor: Unscrew or unclip the old ignitor from its mounting bracket. Handle with care as it may be fragile.
5. Install New Ignitor: Attach the new AUX060C936D3 ignitor to the provided mounting bracket using the included screws. Ensure the ignitor is positioned correctly according to the original ignitor's orientation.
6. Mount Ignitor Assembly: Secure the new ignitor assembly into the furnace, ensuring it is firmly in place and properly aligned with the burner.
7. Connect Wiring: Connect the electrical wires to the new ignitor. Ensure connections are tight and secure.
8. Secure Panels: Close and secure all furnace access panels.
9. Restore Power and Test: Restore electrical power to the furnace. Initiate a heating cycle to verify proper ignition and operation. Observe the ignitor glowing and the burner igniting.

5. Operating Principles

The hot surface ignitor is an integral part of a modern furnace's ignition system. When the thermostat calls for heat, the furnace control board sends voltage to the ignitor, causing its silicon-nitride element to heat up to a very high temperature (glowing red). Once the ignitor reaches the optimal temperature, the gas valve opens, and the hot surface ignitor ignites the gas. A flame sensor then confirms the presence of a flame, allowing the furnace to continue its heating cycle.

6. Maintenance

The AUX060C936D3 ignitor is generally a maintenance-free component. However, regular inspection during annual furnace maintenance is recommended. A qualified technician should:

• Visually inspect the ignitor for cracks, chips, or signs of overheating.
• Ensure electrical connections are clean and secure.
• Check for any obstructions around the ignitor that could impede proper operation.

If any damage is observed, the ignitor should be replaced by a qualified professional.

7. Troubleshooting

If your furnace is not igniting, the hot surface ignitor may be a potential cause. Always consult a qualified HVAC technician for diagnosis and repair.

Common Symptoms of a Faulty Ignitor:

• No Ignition: The furnace attempts to start, but the ignitor does not glow, and no flame is established.
• Intermittent Ignition: The ignitor glows, but the flame does not consistently light, or it lights and then goes out.
• Visible Damage: The ignitor element appears cracked, chipped, or broken.

Before troubleshooting, ensure all power to the furnace is disconnected.

Basic Checks (by a qualified technician):

• Verify that the ignitor is receiving the correct 80V power supply from the control board.
• Check for continuity across the ignitor element. A lack of continuity indicates a broken element.
• Ensure all wiring connections are secure and free of corrosion.

If the ignitor is determined to be faulty, it must be replaced with an appropriate OEM part like the AUX060C936D3.
