Lennox 63W59 Sensor Harness
The Lennox 63W59 Sensor Harness (OEM Part 101334-03) is a critical component for maintaining precise thermal monitoring within RT13 and RT28 HVAC systems. This 50-inch defrost sensor wiring harness is engineered with 24 AWG leads to ensure signal integrity between the controller and the outdoor coils. The assembly features a specialized configuration including Sensor #1 with a fixed resistor, alongside Sensors #2 and #3, allowing the defrost control board to accurately calculate coil temperatures and initiate defrost cycles only when necessary. Utilizing this Lennox OEM replacement part mitigates the risk of nuisance trips and frost accumulation caused by high-resistance connections often found in universal or corroded harnesses. For technicians servicing commercial package units or split systems, this harness provides the exact lead lengths and connector pinouts required for a direct-fit installation, ensuring the defrost sensor function meets original factory specifications for system efficiency and compressor protection.
Key Technician Benefits
- Direct OEM Match: Replaces factory part 101334-03, ensuring plug-and-play compatibility with RT13 and RT28 control logic.
- Precision Engineering: Includes integrated fixed resistor on Sensor #1 to maintain calibrated voltage drops required by the motherboard.
- Durable Construction: Features 24 AWG wiring rated for high-vibration environments typical of condenser fan sections.
- Optimized Length: The 50-inch span allows for clean routing away from high-voltage leads to prevent electromagnetic interference.
- Complete Assembly: Includes sensors #1, #2, and #3 to facilitate a full system refresh of the defrost temperature sensing circuit.
Common Questions
Does this harness work with universal defrost boards?
This Lennox 63W59 assembly is specifically designed for Lennox HVAC equipment. Because Sensor #1 utilizes a specific fixed resistor, it must be paired with compatible Lennox controllers to ensure accurate temperature readings.
Can I use this for RT13 and RT28 systems only?
While optimized for RT13 and RT28 systems, this harness is used extensively across various Lennox commercial units. Always verify the OEM part number 101334-03 in the service manual to confirm the thermistor curves match your specific control board.
What wire gauge is used in the 63W59?
The harness utilizes 24 AWG wiring, providing the necessary flexibility for tight routing while maintaining low electrical resistance for sensitive thermistor signals.
