Bard 8402-186BX is an OEM compressor overload protector used on certain Bard wall-mounted packaged air conditioner models to help safeguard the compressor by opening the circuit when excessive heat or amperage conditions occur. Replacing a weak or nuisance-tripping overload with the correct Bard factory part can restore dependable compressor operation and reduce repeated shutdowns that look like hard-start or low-voltage issues. This part is referenced in Bard W12AB series replacement parts documentation as a compressor overload option depending on unit configuration, so confirm the correct match by model and serial before ordering to ensure proper fit and protection characteristics.
* 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.
