Lennox 15M35 Wiring Harness

In the field, reliability is non-negotiable, and the Lennox 15M35 Wiring Harness is the professional standard for single-phase compressor connections. This molded wiring harness is a direct replacement for the legacy Lennox 15M3501 part number, ensuring seamless integration with original equipment. Engineered for high-voltage stability, it is rated for up to 600 VAC and features a robust 10 AWG main lead construction to handle significant current draws without thermal failure. The harness spans 65 inches in length, providing ample reach for various cabinet configurations in residential and light commercial units.

The Lennox 15M35 utilizes a specialized 3-pin compressor plug designed specifically for single-phase scroll and reciprocating compressors. Its molded plug design effectively seals the electrical terminals against moisture and contaminants, preventing the common arcing issues found in generic universal kits. With color-coded leads (typically Black, Yellow, and Red), it simplifies HVAC compressor wiring and ensures phase consistency during installation. For technicians servicing Lennox, Armstrong, or Ducane systems, this OEM replacement part is essential for maintaining factory-spec voltage delivery and system protection.

• Direct Compatibility: Engineered as a drop-in replacement for the Lennox 15M3501, 72L40, and 15M30 models.
• High-Capacity Conductivity: Features 10 gauge wire rated for 600V, ideal for high-demand compressor startups.
• Environmental Protection: The molded compressor plug provides a secure, moisture-resistant connection to the terminal pins.
• Service Efficiency: 65-inch lead length and standardized color coding reduce diagnostic and installation time during motor or compressor swaps.

• Is the 15M35 compatible with 15M3501? Yes, these part numbers are functionally identical and interchangeable for all single-phase applications.
• What is the maximum voltage rating? This harness is strictly rated for up to 600 VAC, covering all standard 208/230V residential and commercial single-phase systems.
• What wire gauge is used? It utilizes a combination of 10 AWG and 14 AWG leads to ensure minimal voltage drop over the 65-inch run.
