Reznor 272626 Ignition Board
When you're troubleshooting a Reznor unit heater that won't initiate the burn, the Reznor 272626 Ignition Board—also identified by technical reference 1171-350 YD—is the primary diagnostic point for sequence control. This OEM Reznor ignition control board is engineered specifically for commercial and industrial unit heaters, managing the critical timing between the inducer motor proving and gas valve energization. As a veteran-grade HVAC replacement part, it features an integrated microprocessor that monitors flame rectification and safety limits to prevent hazardous conditions like delayed ignition or unburned gas accumulation. During a service call, verify the integrated LED diagnostic codes on the 1171-350 YD ignition board to pinpoint if a lockout is triggered by a pressure switch failure or a flame sensor signal loss. This genuine furnace control module ensures heavy-duty reliability in demanding rooftop or warehouse environments where precise combustion control is non-negotiable for system uptime.
Key Benefits for Technicians
- Direct OEM Replacement: Matches existing wiring harnesses for the Reznor 272626, eliminating the need for field modifications or bracket fabrication.
- Advanced Diagnostics: Onboard LED flash codes provide immediate feedback on system faults, significantly reducing labor time during HVAC troubleshooting.
- Safety Interlocks: Constantly monitors the high limit switch and flame rollout sensors to ensure safe ignition cycles.
- Industrial Build Quality: High-tolerance circuitry designed to withstand the thermal stresses and frequent cycling typical of Reznor gas-fired unit heaters.
Common Technical Questions
Why is the LED on my Reznor 272626 board flashing three times?
A three-flash code typically indicates a combustion air pressure switch failure or a limit switch is open. Check for restricted venting or a failing inducer motor before replacing the module.
Does this board replace the older 1171-350 series?
Yes, the 1171-350 YD is the current technical standard for this revision. Always cross-reference your specific heater model and serial number to ensure full pin-compatibility with the 272626 part number.
Can I test the flame sensor through this ignition board?
You can measure the microamp (μA) signal directly through the flame sensor lead while the board is energized to verify if the ignition board is accurately detecting the pilot or main burner flame.
