Amana-Goodman C6437502 Flame Sensor

The Amana-Goodman C6437502 Flame Sensor is a critical OEM replacement component engineered for precision flame rectification in gas-fired furnaces. As a high-performance HVAC flame sensor replacement, this probe monitors the burner's ionized gas to ensure the furnace control board maintains the gas valve circuit. If you are troubleshooting a furnace short cycling issue or a lockout condition where the burner ignition fails after a few seconds, this sensor is the definitive technical solution. It serves as the direct cross-reference for legacy part numbers C6437501, C6437503, and the PSE-AM2. Constructed with high-grade ceramic insulation and a durable metallic probe, it is designed for maximum thermal resistance within the combustion chamber. This genuine Goodman replacement part ensures seamless compatibility with Amana and Goodman heating systems, preventing carbon buildup and maintaining accurate microamp signals for safe, reliable operation throughout the heating season.

• OEM Precision: Specifically calibrated for Amana-Goodman control boards to ensure accurate microamp (µA) signal readings.
• Direct Application Compatibility: Replaces C6437501 and C6437503 without the need for mounting modifications.
• High-Temperature Durability: Engineered with premium materials to resist oxidation and withstand extreme furnace heat cycles.
• Safety Compliance: Vital for preventing unburned gas accumulation by confirming flame presence during every ignition cycle.

How do I know if my Amana-Goodman flame sensor is bad?
If the furnace ignites but shuts down within 2–5 seconds, the sensor is likely failing to send a rectification signal. Check for cracks in the ceramic or heavy carbon deposits on the probe.

Can I clean the C6437502 instead of replacing it?
While light cleaning with a non-abrasive pad may provide a temporary fix, internal degradation or cracked insulation requires a full replacement to ensure long-term reliability and code compliance.

Is the C6437502 compatible with other furnace brands?
This part is specifically engineered for Amana and Goodman units. Always verify the cross-reference list, including C6437501 and PSE-AM2, before installation.
