Reznor 195653 Wiring Harness

The Reznor 195653 Wiring Harness is a critical OEM replacement part engineered specifically for high-efficiency unit heaters. This 5-pin wiring harness serves as the primary electrical interface for mid-range heating equipment, facilitating precise communication between the integrated control board and vital system components such as the inducer motor, gas valve, and spark igniter. Designed for the Reznor UDAP, UDAS, UDBP, and UDBS series, it is optimized for units ranging from 30,000 to 125,000 BTU capacities. For service technicians, this harness eliminates the need for field-splicing, ensuring a drop-in HVAC wire harness solution that maintains factory-spec electrical resistance and signal integrity. The robust wiring harness 5-pin configuration utilizes keyed connectors to prevent improper indexing during installation, reducing the risk of control board shorts and ensuring reliable operation in demanding commercial or industrial environments.

Key Benefits:

• Ensures a secure, factory-standard 5-pin wiring harness connection for Reznor heating equipment.
• Hard-keyed connectors eliminate cross-wiring errors during field replacement.
• Facilitates seamless unit heater electrical repair on UDAP, UDAS, UDBP, and UDBS models.
• Engineered by Nortek to handle the thermal and electrical loads specific to 30-125K BTU systems.
• Reduces diagnostic time by providing a reliable link between the motherboard and peripheral sensors.

Common Questions:

Is the Reznor 195653 compatible with larger 150K-400K BTU units?
No. This specific harness is designed for the 30-125K BTU range. Larger units typically require the 195656 harness or a model-specific configuration to handle different amperage requirements.

Why should I use an OEM Reznor harness instead of a universal connector?
The 195653 uses specific pinouts and wire gauges tailored to the Nortek control boards. Using non-OEM alternatives can lead to high-resistance connections, resulting in inconsistent flame signals or premature component failure.

Does this harness include the main control board?
No, this is the 5-pin wiring assembly only. It is intended to replace damaged, brittle, or corroded wiring between the existing board and the heater components.
