Bard 8620-374 - Overflow Switch Replacement Kit

The Bard 8620-374 Overflow Switch Replacement Kit is an OEM safety control kit designed to help prevent condensate overflow problems in Bard wall-mounted HVAC equipment. When a drain line plugs, a pump fails, or the drain pan water level rises unexpectedly, an overflow switch opens the control circuit to shut the system down before water can spill into the building. Replacing a weak or failed overflow switch with the correct Bard kit helps restore reliable condensate protection and reduces nuisance water-related service calls. Confirm compatibility by matching the part number to your unit model and serial tag or the Bard parts list for your specific series and revision before ordering.
