Bard HVAC 8552-090 Run Capacitor

For service technicians and mechanical contractors maintaining Bard wall-mount equipment, the Bard HVAC 8552-090 Dual Run Capacitor is a critical OEM replacement part for ensuring motor and compressor stability. This 20/5 MFD 440V capacitor features a dual-rated design, providing the necessary phase shift for both the compressor and condenser fan motor. Rated at 440VAC, this round dual run capacitor can safely replace 370V units, offering increased dielectric strength and thermal headroom in high-ambient environments. Verified for cross-compatibility with Bard 8552-090BX and previous 8552-090 revisions, this component utilizes a standard round 2-inch diameter form factor for a precise fit into existing mounting straps. Built to handle 50/60Hz frequencies, it includes standard 1/4 inch male quick-connect terminals (C, FAN, HERM) for efficient field wiring. Replacing a weak or bulging AC capacitor with this high-quality 20/5 microfarad unit prevents hard starting, motor winding overheating, and expensive compressor failures in Bard HVAC systems.

Key Benefits

• Dual-Value Performance: Provides 20+5 MFD capacitance to simultaneously support the compressor (Herm) and the outdoor fan motor.
• High Voltage Tolerance: Rated for 440 Volts, providing superior durability compared to standard 370V components in heavy-duty cycles.
• OEM Compatibility: Specifically engineered for Bard wall-mount units, ensuring electrical specs align perfectly with factory motor requirements.
• Standardized Form Factor: The round aluminum can design fits standard 2" mounting brackets without the need for field modifications.
• Terminal Identification: Clearly marked C, Fan, and Herm terminals for error-free installation and reduced diagnostic time.

Common Questions

Can I use a 440V capacitor if my original Bard unit has a 370V rating?
Yes. Vocational standards allow for a higher voltage rating than the original (e.g., replacing 370V with 440V), as this represents the insulation's maximum peak capacity. However, you must never install a capacitor with a lower voltage rating than the original equipment specifies.

What are the signs of a failing Bard 20/5 MFD run capacitor?
Technicians should look for physical bulging at the top of the can, oil leakage around the terminals, or a "humming" motor that fails to start. Testing with a multimeter should show a capacitance value within +/- 5% of the 20/5 microfarad rating; values outside this range indicate internal decay.

Is the Bard 8552-090BX the same as the 8552-090?
The 8552-090BX is the current manufacturer-specified boxed replacement for the 8552-090. They share identical 20/5 MFD 440Vac specifications and are interchangeable for all Bard HVAC applications requiring this microfarad value.
