Bard 3018-1473A (AG2K-56-YE2) is an OEM electrical/control component used in Bard HVAC equipment to switch and manage circuit operation when the unit calls for cooling or heating functions. Replacing a worn or intermittent control device with the correct Bard part helps restore dependable start-up, proper sequencing, and stable operation under load, which can prevent nuisance shutdowns and reduce troubleshooting time. For best results, match the part number to your unit’s parts list or wiring diagram and confirm coil and contact ratings before installation so the replacement fits and performs exactly like the factory original.
