The Goodman B1172605 Flame Sensor is the genuine OEM flame-rectification rod for the GUS125-5 gas furnace. This sensor confirms the burner has lit and sends that signal to the control board; without a valid flame signal, the board closes the gas valve as a safety measure. A dirty, corroded, or cracked flame sensor is the single most common cause of a furnace that lights for a few seconds and then shuts off (short-cycling on flame loss).

Specifications

Part Number: B1172605 (OEM)
Type: Flame-rectification sensor rod
Fits: Goodman GUS125-5 gas furnace
Function: Confirms burner flame presence to the ignition control
Brand: Goodman OEM replacement

OEM vs. Generic

The OEM B1172605 uses the correct rod length, bracket angle, and terminal so it seats in the burner flame envelope exactly where the GUS125 needs it. Generic sensors often sit at the wrong depth and produce a weak microamp signal, causing intermittent lockouts. At this price point, OEM is an easy call.

Installation Difficulty: Easy

One screw and one push-on wire terminal. Shut off power, remove the old rod, install the new one, and restore power. A 10-minute repair and one of the highest-value fixes in furnace maintenance.
