Furnace Flame Sensor Repair nationwide

When you require furnace flame sensor repair, Furnace Repair Pros brings you licensed, insured service in 4,741 cities across 51 states - the same flat-rate pricing and written guarantee everywhere. The flame sensor is a small but critical safety device: a metal rod positioned in the burner flame that sends a microamp signal to the control board confirming that combustion is actually happening. When that rod gets coated with carbon, oxidation, or silica from dirty combustion, the signal weakens and the board shuts the gas valve down within seconds - often after the burners light and then go out, leaving you with short cycling and no heat. Our technicians test the sensor with a microamp meter to confirm the reading is below spec, then remove it and clean the rod with the proper abrasive without damaging the ceramic insulator. If the sensor is cracked, corroded, or out of tolerance, we replace it with an exact-fit OEM or equivalent part. We also inspect the surrounding components - igniter, burners, control board, and grounding - because a weak flame sensor is sometimes a symptom of a larger combustion or airflow problem.

What makes Furnace Repair Pros different is how we combine national reach with genuinely local service. Our network spans 51 states and 4741 cities, with 4,741 service areas staffed by licensed HVAC contractors who live in the communities they serve.

A centralized dispatch system routes your call to the nearest available technician, and our national support team tracks every job to completion. You get the speed and familiarity of a local company with the consistency and accountability of a national brand - no guesswork, no unlicensed handymen, no cut-rate parts.

Every flame sensor repair starts with a written, upfront quote based on a flat-rate price sheet.
