Lennox 13W87 — 50/7.5 MFD 440VAC Round Dual Run Capacitor
The Lennox 13W87 is a genuine OEM round dual run capacitor engineered to deliver consistent, dependable performance in residential and light commercial HVAC systems. Rated at 50/7.5 microfarads and 440 volts AC, this capacitor simultaneously supports both the compressor and the condenser fan motor from a single, compact round housing — reducing component count and simplifying installation.
Key Features
- Dual capacitance rating: 50 MFD (compressor) / 7.5 MFD (fan motor)
- Voltage rating: 440VAC for broad system compatibility
- Round housing design for easy drop-in replacement
- Supports simultaneous compressor and condenser fan motor operation
- Genuine Lennox OEM replacement part — SKU 13W87
- Designed for reliable starting and running performance in air conditioning and heat pump systems
Why Dual Run Capacitors Matter
Dual run capacitors are critical components in air conditioning and heat pump systems. They maintain the proper phase shift needed to start and run both the compressor and condenser fan motor efficiently. A failing capacitor can cause hard starting, reduced efficiency, increased motor wear, or complete system failure. Replacing a worn capacitor with a genuine Lennox OEM part like the 13W87 helps restore peak system performance and protects downstream components.
Application
- Compatible with Lennox air conditioning and heat pump systems requiring a 50/7.5 MFD, 440VAC round dual run capacitor
- Ideal for HVAC technicians performing preventive maintenance or emergency service repairs
