Description
Long Description
The Linebacker LCD45+4X440R is a premium dual run capacitor designed for air conditioners and heat pumps that require a 45/4 microfarad, 440‑volt round motor run capacitor. Dual capacitors power both the compressor and the condenser fan motor, making them essential for proper system operation.
When a capacitor weakens or fails, symptoms such as hard starting, warm air, loud humming, or system shutdown can occur. Replacing it with the LCD45+4X440R restores correct motor torque, smooth operation, and efficient cooling performance.
Linebacker capacitors are engineered to meet or exceed OEM specifications, featuring durable construction, high‑grade dielectric materials, and long service life in demanding HVAC environments.
