ClimateMaster 15B0013N70 Capacitor

The ClimateMaster 15B0013N70 Capacitor is a high-performance 10MFD 440V oval run capacitor engineered specifically for technical compatibility within ClimateMaster water source heat pumps and geothermal systems. As a veteran technician knows, maintaining the correct capacitance rating of 10 microfarads is critical for stabilizing the phase shift in blower motors and compressors. This 440-volt rated component is a robust upgrade for 370V applications, offering superior dielectric strength and heat dissipation to handle back EMF spikes during continuous duty cycles.

Designed with a space-efficient oval form factor, the 15B0013N70 fits standard mounting brackets in tight electrical cabinets. This OEM ClimateMaster part ensures the motor start windings receive the precise amperage required to reach sync speed without overheating. Whether you are servicing a residential geothermal split or a commercial console unit, utilizing an HVAC run capacitor with 50/60Hz compatibility and a single-run configuration is essential for maximizing energy efficiency and protecting expensive motor windings from premature failure due to electrical strain.

• Precision Capacitance: Rated at 10 MFD to ensure optimal torque and peak motor efficiency.
• High-Voltage Tolerance: 440VAC rating provides a safer operating margin compared to standard 370V capacitors.
• Thermal Reliability: Built with high-quality dielectric materials to withstand the rigorous temperatures of HVACR environments.
• OEM Fitment: Genuine ClimateMaster replacement part ensures exact physical and electrical terminal alignment.
• Versatile Application: Suitable for both 50Hz and 60Hz systems across various heat pump models.

Can I use this 440V capacitor if the original was 370V?
Yes. In HVACR applications, you can always go up in voltage rating (e.g., 370V to 440V), as this represents the "not-to-exceed" limit. However, never decrease the voltage rating or diverge from the 10 MFD capacitance specification.

What are the signs that a ClimateMaster run capacitor has failed?
Technicians should look for oil leaks, a bulged "shroomed" top casing, or a motor that hums but fails to start. Testing with a multimeter should show a reading within +/- 5% of the stated 10 microfarad rating.

Why choose an oval capacitor over a round one?
The oval run capacitor geometry is strictly for physical fitment. If the unit's original mounting bracket is designed for an oval footprint, this 15B0013N70 ensures a secure installation without requiring field modifications.
