8406-158 OBSOLETE
- Low Pressure Transducer - Blue
Bard part number 8406-158 is an OEM low pressure transducer used to monitor system pressure and send a stable feedback signal to the unit controls so the equipment can protect the refrigerant circuit and maintain proper operation. When a transducer drifts out of range or fails, it can trigger pressure related faults, incorrect compressor staging, or nuisance lockouts, so replacing it with the correct Bard sensor helps restore normal diagnostics and control response. Match 8406-158 to your unit model and wiring harness, and verify the pressure port connection and control input requirements in the Bard service documentation before ordering to ensure proper fit and function.
