Lennox 53H12 Run Capacitor

The Lennox 53H12 is a professional-grade 10 Microfarad 440Vac Round Run Capacitor designed for high-duty cycle applications in Lennox residential and light commercial HVAC systems. This OEM replacement part, also identified by part number 53H1201, is critical for maintaining correct motor phase displacement and ensuring efficient compressor or fan motor operation. Rated for 440V, it provides superior overhead for systems currently using 370V components, effectively handling higher voltage spikes and reducing heat-related failure. Technicians will find the 10 MFD capacitance rating and ±5% tolerance provide the precise electrical characteristics required to meet factory performance specifications. Its physical round metal can construction facilitates rapid heat dissipation and fits standard mounting brackets. Replacing old units with this genuine Lennox 53H1201 eliminates common performance issues like high amperage draws or failing starts, ensuring the HVAC capacitor maintains stable system power factors and improves long-term motor winding health in demanding climates.

• OEM Compatibility: Fully interchangeable with Lennox part number 53H1201, ensuring a precise fit and factory-spec performance.
• Industrial Build: Rated at 440V for enhanced durability compared to standard 370V alternatives.
• System Efficiency: Maintains a 10 MFD capacitance to optimize motor torque and reduce energy consumption.
• Standardized Form Factor: Round capacitor housing allows for quick installation in existing Lennox motor assemblies.

• Can I use the 53H12 to replace a 370V capacitor? Yes, the 440V rating is a superior upgrade for 370V applications and provides better resistance to thermal stress.
• Is the Lennox 53H1201 the same as the 53H12? These parts are identical in technical specifications and are used interchangeably by HVAC service technicians.
• What happens if my 10 MFD run capacitor fails? A failing capacitor typically leads to motor overheating, increased amperage, or the inability of the compressor to start under load.
