Goodman B1172605 Flame Sensor

The Goodman B1172605 is a genuine OEM flame sensor rod for the GUS075-3 gas furnace. The flame sensor confirms the burners have actually lit by reading the tiny microamp current that flame conducts to ground. When the rod corrodes or gets coated in oxide, the control board can't verify flame and shuts the gas valve after a few seconds — the classic symptom of a furnace that lights, runs 3–7 seconds, then shuts off and retries (short-cycling on flame failure).

Specifications

Part Number: B1172605
Type: Flame sensor / flame rectification rod
Function: Confirms burner ignition via microamp flame signal
Fits: Goodman GUS075-3 gas furnace
Single-screw mount with spade terminal

OEM vs. Generic

The OEM B1172605 has the exact rod length and bend so the tip sits correctly in the burner flame envelope for a strong, stable signal. Generic sensors often sit too high or low in the flame, giving a weak microamp reading that fails again within weeks. At this price, genuine OEM is a no-brainer.

Install Difficulty: Easy

Rated Easy — a 10-minute job and one of the most satisfying DIY furnace fixes. Cut power, remove one screw and the wire terminal, and install the new rod. Tip: keep a spare on hand; flame sensors are cheap and a common annual maintenance item.
