4. Installation/Setup

The following are general steps for replacing a furnace ignitor. Specific procedures may vary by furnace model. Consult your furnace's service manual or a qualified technician for detailed instructions.

1. Safety First: Turn off all electrical power to the furnace at the circuit breaker and turn off the gas supply.
2. Access the Ignitor: Locate the ignitor within the furnace. This usually involves removing an access panel.
3. Disconnect Old Ignitor: Carefully disconnect the wiring from the old ignitor. Note the routing of the wires.
4. Remove Old Ignitor: Unscrew or unclip the old ignitor from its mounting bracket. Handle with care as it may be brittle.
5. Install New Ignitor: Gently attach the new ignitor to the mounting bracket. Ensure it is securely fastened and positioned correctly. Avoid touching the ceramic element.
6. Connect Wiring: Connect the new ignitor's wiring. Use the provided wire nuts if necessary, ensuring a secure electrical connection.
7. Restore Power: Replace any access panels. Restore the gas supply and electrical power to the furnace.
8. Test Operation: Initiate a heating cycle to confirm the ignitor is functioning correctly and the furnace lights properly.

5. Operation

The furnace ignitor operates as part of the furnace's ignition sequence. When the thermostat calls for heat, the ignitor receives electrical current and rapidly heats up to a high temperature. This hot surface then ignites the gas flowing from the burner. Once the flame is established and detected by the flame sensor, the ignitor's circuit is typically de-energized until the next heating cycle is initiated.

6. Maintenance

Regular maintenance of your furnace is crucial for its longevity and efficient operation. While the ignitor itself is not typically a user-serviceable part for cleaning or repair, its condition should be inspected during routine furnace maintenance by a qualified technician. Signs of wear, cracks, or discoloration on the ignitor element may indicate a need for replacement.

7. Troubleshooting

If your furnace is not igniting, the ignitor may be a potential cause. Common symptoms of a faulty ignitor include:

• The furnace fan runs, but no heat is produced.
• You hear a clicking sound (from the gas valve attempting to open) but no ignition.
• The ignitor glows for a short period and then goes out without igniting the gas.
• The ignitor does not glow at all.

Before assuming the ignitor is faulty, ensure that the furnace has power, the gas supply is on, and the thermostat is set correctly. If these basic checks do not resolve the issue, it is recommended to contact a qualified HVAC technician for diagnosis and repair. Attempting to troubleshoot or repair complex furnace components without proper training can be dangerous.
