Reznor 207502 Electrode Assembly

The Reznor 207502 is a genuine OEM Reznor electrode assembly designed for Direct Spark Ignition (DSI) systems. This 24-inch assembly is critical for maintaining reliable burner ignition in Reznor gas-fired unit heaters and commercial HVAC systems. By delivering a high-voltage spark directly to the burner, the Reznor 207502 DSI electrode ensures consistent pilotless ignition, preventing frequent lockouts and ignition failure incidents. As a veteran HVAC technician knows, using OEM Reznor heater parts is essential for maintaining the original equipment’s efficiency and flame sensing accuracy. This assembly is built for high-heat environments and frequent cycling, featuring a 3/16-inch size lead wire distribution to provide a stable electrical path. When performing a Reznor furnace repair or scheduled maintenance, replacing a fouled or cracked electrode with the 207502 ensures the burner assembly operates at peak performance, reducing downtime in industrial or commercial installations where heating reliability is paramount.

• Extended Reach: The 24-inch length provides the necessary clearance for larger burner boxes found in high-capacity Reznor units.
• Compatibility: Direct replacement for the Reznor 207502 part number, ensuring an exact fit in compatible unit heaters.
• Industrial Durability: Constructed to withstand high-temperature combustion zones and vibration from blower motors.
• Optimized Efficiency: Helps prevent gas accumulation by ensuring rapid ignition, improving overall system safety.

Common Questions

What causes a Reznor DSI electrode to fail?
Cracked ceramic insulation or heavy carbon buildup are the primary culprits. If the spark jumps to the cabinet instead of the burner, or if the flame sensor signal is weak, the Reznor 207502 likely needs replacement.

Can I use this for any Reznor heater?
This part is specifically designed for Reznor gas-fired units using a 24-inch lead DSI system. You should always verify your specific model and serial number against the Reznor heater parts list before installation.

Why choose an OEM electrode over a generic alternative?
OEM electrodes like the 207502 Reznor assembly are precision-calibrated for the correct gap and insulation resistance, which is critical for the control board to accurately detect a flame signal and prevent nuisance shutdowns.
