8406-139 OBSOLETE
- OVERFLOW SWITCH
Bard 8406-139 is an OEM overflow switch assembly used in Bard wall mount HVAC equipment to protect the unit and the space from condensate overflow conditions. When a drain pan or condensate management issue causes water to back up, this safety switch is designed to signal the controls to help prevent continued operation that could lead to water damage or nuisance shutdowns. As a distributor, we recommend confirming your exact Bard model and serial number and checking the unit wiring diagram or parts list to verify correct fit, since overflow switch arrangements can vary by series and control panel configuration.
