Bard 3018-735 - OEM control component

Bard part number 3018-735 (AG4-44-AY) is an OEM control component used in Bard wall mounted equipment to support proper low voltage control operation, helping the unit respond correctly to calls for cooling and any configured safety or accessory functions. This is the type of part technicians replace when troubleshooting inconsistent cycling, control logic issues, or damaged wiring terminations where the correct Bard-specific configuration matters for reliable operation. Because Bard wall mount units can vary by series and vintage, confirm the exact model and serial number from the unit nameplate and match the part number 3018-735 to the appropriate parts list or service manual before ordering to ensure correct fit and function.
