Bard part 3000-1289 is an OEM low voltage wire harness used in Bard QTEC series packaged heat pump equipment, connecting the low voltage terminal strip to connector PL2 to restore reliable communication between the thermostat and the unit controls. If you are troubleshooting intermittent control signals, loose field wiring, or damaged conductors at the control panel, replacing this factory harness helps return the unit to proper, predictable operation while maintaining correct fit, routing, and connector integrity compared to aftermarket alternatives. Verify your unit model and wiring diagram to confirm this harness matches your specific control configuration before ordering.
