Reznor 195265 Control Board

The Reznor 195265 DSI Control Board is a critical Nortek OEM replacement part engineered for direct spark ignition within Reznor gas-fired unit heaters. This 24V integrated ignition control (UTC 1097-210) manages the complete combustion sequence, including power venter activation and gas valve control, to ensure safe and efficient burner operation. Built for high-reliability environments, the Reznor 195265 features integrated LED diagnostics that provide immediate status indicators and fault codes, significantly reducing troubleshooting time during service calls. This board is the standard circuit board replacement for a wide range of V3 series units, providing the 1A amperage and 60 Hz frequency required for stable performance. Contractors typically utilize this ignition module to resolve unit heater lockout issues or failure to ignite in natural gas and LP applications. Its robust design is compatible with the Reznor UDAP, UDAS, UDBP, and UDBS model series, making it a versatile component for your service van inventory.

• Universal Compatibility: Fits all Reznor UDAP, UDAS, UDBP, and UDBS gas-fired models.
• Advanced Diagnostics: Onboard LED indicator lights display fault codes for rapid system analysis and reduced downtime.
• Precise Ignition Control: Utilizes Direct Spark Ignition (DSI) technology for consistent burner startup in commercial and industrial heating.
• Safety Certified: CSA listed for use with both natural gas and liquid propane configurations.
• Simplified Integration: Direct OEM replacement ensures terminal alignment and HVAC wiring consistency.

What does a flashing LED on the Reznor 195265 mean?
The onboard LED status light communicates diagnostic codes. A specific number of flashes indicates whether the system is in a lockout, experiencing a flame sensor failure, or blocked by a pressure switch issue. Always refer to the unit’s wiring diagram for the exact error code definitions.

Can this board be used for LP (Propane) units?
Yes, the Reznor 195265 is designed for gas-fired unit heaters operating on either natural gas or LP gas, provided the gas valve and orifices are correctly configured for the fuel type.

Why is my unit failing to ignite with a new control board?
If the 195265 board is receiving 24V power but the burner won't light, check the flame sensor (Reznor 195292), the igniter gap, and the 3-amp fuse. Ensure the power venter is reaching full speed to trip the combustion air pressure switch.
