• Dual Pressure Control DPC-MRA Boxed

Bard part number 8406-018 is an OEM dual pressure control (DPC-MRA, boxed) used on Bard wall-mounted air conditioners and related packaged equipment to monitor refrigerant system pressures and help protect the compressor from unsafe operating conditions. In the field, this control is typically replaced when a unit is nuisance-tripping, locked out on a pressure safety, or has confirmed switch/contact issues, and using the correct Bard part helps ensure the pressure cutout and reset behavior matches the original unit design. Verify compatibility by matching the full part number and checking your Bard unit model and wiring diagram, since pressure safety controls can vary by application and control strategy.
