- Low Pressure Control Assembly
The Bard 1804-0338 Low Pressure Control Assembly is an OEM safety control used on Bard wall-mount and packaged HVAC equipment to monitor the refrigerant suction (low-side) pressure and protect the system during abnormal conditions such as low charge, restricted airflow, or freeze-up risk. When low pressure drops outside the intended operating range, this control helps interrupt compressor operation to prevent damage and nuisance failures, making it a smart replacement when troubleshooting repeated low pressure trips or intermittent cooling complaints. Use the part number 1804-0338 to confirm exact fit to your unit model and serial, and install and verify operation per the applicable Bard service literature so the refrigeration circuit and wiring are returned to factory-correct protection.
