  • 8408-017 OBSOLETE

  • DEFROST THERMOSTAT 32/57

Bard part 8408-017 is an OEM defrost thermostat rated 32/57, used in Bard heat pump defrost circuits to help control the defrost heater operation based on coil temperature. When this temperature switch is operating correctly, it helps prevent outdoor coil ice buildup while also avoiding unnecessary defrost heat, keeping the unit running efficiently in cold weather. As a distributor, we recommend matching this thermostat to the exact Bard unit model and wiring diagram before ordering since defrost components can vary by series and control strategy, and using the correct Bard OEM part helps maintain proper cut-in and cut-out behavior during defrost.
