Lennox 53H27 Capacitor

The Lennox 53H27 is a high-performance 35/5 MFD 440V Oval Dual Capacitor engineered for professional-grade HVACR applications. Designed to replace legacy part number 53H2701, this dual run capacitor provides critical start-up torque and operational stability for both the compressor and the condenser fan motor. Built with a rugged, corrosion-resistant aluminum casing, the 35/5 uF dual run capacitor is rated for 440 VAC, offering superior dielectric strength and a higher safety margin compared to 370V alternatives. Its compact oval dual capacitor form factor allows for seamless integration into tight electrical service panels found in Lennox, Armstrong, and Ducane residential condenser units.

For technicians in the field, this OEM Lennox capacitor ensures proper phase shift and motor efficiency, preventing premature winding failure and reducing amperage draw during high-load cooling cycles. The 53H27 capacitor features standard 1/4-inch male quick-connect terminals clearly marked for Herm, Fan, and Common connections, facilitating quick diagnostic testing and replacement. Whether you are performing a seasonal tune-up or an emergency service call, utilizing a high-tolerance HVAC dual run capacitor like the 53H27 is essential for maintaining the torque and RPM specifications necessary for optimal refrigerant compression and heat dissipation.

• Dual-Function Reliability: Consolidates both the 35 MFD compressor and 5 MFD fan motor circuits into a single, high-efficiency 35/5 MFD capacitor.
• High Voltage Compatibility: Rated at 440V to provide a robust buffer against line voltage fluctuations and power surges.
• OEM Precision: Direct replacement for Lennox 53H2701, ensuring exact electrical and physical fitment for Lennox-branded equipment.
• Space-Saving Design: The oval-shaped aluminum casing fits standard mounting brackets in compact outdoor cabinets.
• Heavy-Duty Construction: Sealed against moisture and environmental contaminants for consistent performance in extreme outdoor conditions.

Can I use the Lennox 53H27 to replace a 370V capacitor?
Yes, a 440V capacitor like the 53H27 can safely replace a 370V unit with the same capacitance ratings, as it possesses a higher dielectric rating. However, a 370V capacitor should never be used to replace a 440V unit.

How do I identify a failing 53H27 capacitor?
Technicians should look for a "bulged" or distorted top header, signs of terminal leakage, or a capacitance reading that has drifted more than 5%–10% from the nominal 35/5 microfarad rating.

What equipment is compatible with the Lennox 53H27?
This capacitor is commonly found in Lennox HP25, 13ACX, and 14ACX series units, as well as various Armstrong and Ducane air conditioners and heat pumps requiring a 35/5 440V oval capacitor.
