Reznor 126101 Flame Probe

The Reznor 126101 Flame Probe is a critical OEM safety component engineered for SCA-6 (Y75GB-1) series gas-fired unit heaters. As an auxiliary flame sensor, this part identifies the presence of a burner flame to prevent the hazardous accumulation of unburned gas by signaling the ignition control board to maintain or interrupt the gas flow. Constructed with high-durability materials and featuring an integrated mounting bracket, the Reznor 126101 ensures stable signal transmission in high-temperature environments. For technicians performing HVAC furnace maintenance or gas heater repair, replacing a fouled or cracked flame sensor for SCA-6 is a standard procedure to resolve intermittent lockout issues or ignition failures. This genuine Reznor heating part provides the precise millivolt signal required for modern control modules, ensuring your commercial or industrial heating system operates with maximum safety and efficiency during the heating season.

• OEM Compatibility: Precision-engineered specifically for the Reznor SCA-6 (Y75GB-1) series for drop-in installation.
• Enhanced Safety: Reliable burner flame detection prevents unburned fuel buildup and potential combustion hazards.
• Durable Construction: High-grade auxiliary flame sensor materials withstand persistent thermal stress for a longer service life.
• Direct Fit: Includes the necessary mounting bracket to ensure correct electrode positioning within the burner flame.

How do I know if the Reznor 126101 Flame Probe needs replacement?
If your Reznor SCA-6 heater ignites but shuts down after a few seconds, the flame sensor may be fouled with carbon or have a cracked insulator. Cleaning the probe is a temporary fix, but replacement is recommended for long-term reliability.

Is the 126101 compatible with other Reznor series?
This specific flame probe is cataloged for the SCA-6 (Y75GB-1). Always verify your heater's full model and serial number against the HVAC replacement parts list to confirm a match.

What causes a Reznor flame probe to fail?
Common causes include heavy oxidation, soot buildup from improper combustion, or moisture exposure leading to a bridge between the electrode and the burner ground.
