Bard part number 8552-079BX is an OEM dual run capacitor rated 45/10 MFD at 370V, used in Bard wall mounted HVAC equipment to provide the correct phase shift and running assistance for the compressor and fan motor so they start smoothly and maintain stable operation. A weak or failed run capacitor can cause hard starting, overheating, nuisance trips, or the outdoor fan or compressor not running, so replacing it with the correct Bard specified microfarad ratings and voltage is critical for proper performance and motor life. Match the 45/10 MFD rating exactly and verify safe power isolation before installation, since this is a high voltage electrical component inside the unit control compartment.
* Orders less than $50 may incure a minimum order fee.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
