Lennox 10W37 Dual Run Capacitor 80/7.5 MFD 440 VAC Round

The Lennox 10W37 is a genuine OEM dual run capacitor designed for use in HVAC systems, including air conditioners, heat pumps, and condensing units. Rated at 80 + 7.5 MFD (microfarad) at 440 VAC, this round capacitor supports both the compressor and the fan motor in a single unit, simplifying installation and reducing component count.

A dual run capacitor keeps both the compressor and fan motor running efficiently after startup, maintaining proper phase and voltage to each motor winding. Replacing a failing capacitor is one of the most common HVAC service repairs and is critical to system longevity and performance.

Key Features:

• Capacitance: 80 + 7.5 MFD (microfarad), ±5% tolerance
• Voltage Rating: 440 VAC
• Frequency: 50/60 Hz
• Shape: Round
• Function: Dual run — supports both compressor and fan motor
