Amana-Goodman B1172605 Flame Sensor

The Amana-Goodman B1172605 Flame Sensor is a critical OEM replacement component designed to maintain the flame rectification circuit in high-efficiency gas furnaces. As a genuine Goodman furnace part, this sensor ensures the ignition control module receives a consistent microamp signal, preventing hazardous gas buildup by confirming burner ignition. If you are troubleshooting a furnace short cycling condition or a unit that shuts down within seconds of ignition, a fouled or oxidized HVAC flame sensor is a likely culprit. Engineered for compatibility with wide-ranging Amana and Goodman furnace models including GUS series units, this B1172605 replacement features a high-grade ceramic insulator and a durable metallic sensing rod. Relying on OEM HVAC replacement parts like the B1172605 guarantees the precise dimensions and electrical properties required for safe, long-term operation within the combustion chamber, protecting the heat exchanger from unnecessary thermal stress during failed start attempts.

• OEM Integrity: Precision-engineered Amana-Goodman B1172605 ensures exact fitment and correct microamp output to the control board.
• Enhanced Safety: Reliably detects flame presence to prevent unburned gas from accumulating in the furnace combustion chamber.
• Broad Compatibility: Direct replacement for various Janitrol, Amana, and Goodman gas furnaces, simplifying truck stock management.
• Durable Construction: Features high-temperature resistant porcelain insulation to prevent electrical grounding and signal loss.

How do I know if my Amana B1172605 flame sensor is bad?
The most frequent symptom is the furnace igniting for 2 to 5 seconds and then immediately shutting off. This often repeats for several cycles before the control board goes into a hard lockout. You can verify this by measuring the DC microamps (µA) during the ignition sequence; a reading below 1.0 µA typically indicates a failing or dirty sensor.

Can I clean the B1172605 instead of replacing it?
While cleaning with a fine abrasive (like a Scotch-Brite pad) can temporarily restore the signal by removing carbon buildup, it is often a short-term fix. Once the sensor's surface becomes pitted or the porcelain insulator develops hairline cracks, a full replacement is required to ensure reliable operation through the heating season.

Where is this sensor located in the unit?
The flame sensor is typically mounted on the burner bracket opposite the ignitor. It consists of a single stainless steel rod positioned directly in the path of the furthest burner flame to ensure the entire burner rack has ignited.
