8406-083 OBSOLETE
- Water Level Switch
The Bard 8406-083 water level switch is an OEM safety control used to monitor condensate level and help prevent overflow conditions in Bard HVAC equipment. When the drain pan or condensate system backs up, this switch is designed to change state and signal the unit to stop cooling operation and protect internal components from water damage. If your Bard unit is shutting down on a condensate fault, intermittently locking out, or you have verified a clogged drain and want to restore proper safety sensing after cleanup, replacing the 8406-083 with the correct Bard part is the right way to maintain factory wiring logic and dependable shutdown behavior. Match the part number to your unit model and serial to confirm application before ordering.
