Technician Notes

• Always shut off power at the furnace and allow the ignitor to cool before servicing.

• Handle the silicon nitride element by its ceramic portion; avoid touching with bare hands to prevent oils and contamination.

• Verify the ignitor grid dimensions (approximately 1 inch square) match OEM specifications.

• Measure resistance at room temperature; expect roughly 70–100 Ω.

• Photograph original ignitor orientation and wiring before removal to ensure correct reinstallation.

• Apply dielectric grease on connector terminals to inhibit corrosion.

• After installation, observe the ignition sequence: the ignitor should glow bright red within 30 seconds of a heat call.

• If ignition fails or is intermittent, confirm the 120 V supply and control board output voltage.
