Bard 3012-157 (DA4-50-CG) is an OEM Bard electrical/control component used in Bard wall-mounted HVAC equipment to support proper system operation by providing the correct factory connection or interface within the unit’s wiring and control circuit. When troubleshooting intermittent operation, no-start conditions, or control-related faults, replacing a worn, damaged, or modified harness or control-circuit component with the correct Bard part helps restore reliable connections and keeps the unit operating as designed. For best fit, confirm this part number against your unit model and serial number or the correct Bard parts manual before ordering.
