Furnace ignitor replacement in San Jose, CA

This furnace had its hot surface ignitor replaced after the original failed to light the burners. A worn or cracked ignitor is one of the most common reasons a gas furnace stops producing heat, so swapping it out restored reliable ignition on every cycle.

Replacing the ignitor on a gas furnace is a precise job that follows a clear sequence to keep the work safe and the furnace running correctly.

How the ignitor replacement was done

• Power shut off: the electrical supply to the furnace was switched off before any panels were opened, eliminating shock and short-circuit hazards.
• Ignitor located: the front cover and access panel were removed so the ignitor could be reached inside the burner compartment.
• Old ignitor removed: the failed component was carefully disconnected and taken out without disturbing the surrounding wiring or burners.
• New ignitor installed: the replacement was fitted in the correct position and reconnected, since the ceramic element is fragile and must be handled with care.
• Furnace tested: power was restored and the furnace was run through a full heating cycle to confirm the burners lit reliably and the unit held a steady flame.

With the new ignitor in place, the furnace fires up dependably and brings the home back up to temperature without missed cycles. Every Nur HVAC repair finishes with a full operational test so the customer knows the system is working before our technician leaves.
