The Bard 3000-1603BX is an OEM transducer wire assembly used on select Bard wall-mounted air conditioners and related packaged systems to connect the pressure transducer into the unit wiring, helping the controls receive accurate pressure feedback for safe, stable refrigeration operation. If you are chasing a pressure-sensing fault, intermittent pressure readings, or a damaged harness at the transducer, replacing this factory-matched wire assembly helps restore proper signal integrity and eliminates fitment guesswork compared with field-made wiring. As with any control-harness replacement, confirm the exact model and serial compatibility in the unit parts manual and verify connector style and routing before installation to prevent chafing or loose connections.
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.
