Reznor 201417 Wiring Harness

The Reznor 201417 Wiring Harness is a critical OEM replacement part designed for high-performance gas-fired unit heaters. Engineered specifically for the power-vented UDAP and separated-combustion UDAS series, this 9-pin terminal harness ensures precise signal transmission between the integrated ignition control board and the unit's mechanical components. It is essential for maintaining the sequences of operation in UDAP150, UDAP175, and UDAP200 models, as well as their UDAS counterparts. Built with high-temp insulation to withstand the rigors of a heat exchanger cabinet, this harness prevents intermittent communication failures that often lead to lockout codes. When diagnosing ignition failure or inducer motor lag in 150-200K BTU units, replacing a brittle or shorted heater wiring assembly with this factory-spec harness is the standard professional fix for restoring system reliability. Proper pin seating in the 9-pin block is mandatory to ensure circuit continuity across all safety and limit controls.

• Precision Compatibility: Exact fit for Reznor UDAP and UDAS models ranging from 150,000 to 200,000 BTU.
• Heavy-Duty Construction: High-grade HVAC wiring designed to resist thermal degradation and vibration-induced fatigue.
• Plug-and-Play Integration: Features a 9-pin terminal connector for rapid, error-free installation during field service.
• OEM Standards: Restores factory-original electrical specifications to prevent control board damage.

Which Reznor models use the 201417 harness?
This specific 9-pin harness is calibrated for the UDAP and UDAS series in the 150, 175, and 200 BTU size range. It is not interchangeable with the smaller 30-125 units or the larger 225-400 units.

Does this harness include the 9-pin plastic housing?
Yes, the Reznor 201417 comes as a complete assembly with the 9-pin terminal block pre-wired for immediate connection to the heater's main control interface.

Can I use this for troubleshooting ignition issues?
Faulty harnesses are a leading cause of "ghost" ignition failures. Replacing a worn harness ensures the flame sensor and gas valve receive consistent voltage without resistance drops.
