Bard part number 8407-019 is an OEM buck boost transformer used to correct supply voltage between 230V and 208V so your Bard wall-mounted air conditioner or heat pump can operate at the intended electrical input. This transformer is typically applied when a site has 208V power available but the unit is configured for 230V, or when the opposite correction is needed, helping prevent nuisance trips, low-voltage issues, and performance problems tied to improper line voltage. Use 8407-019 when your Bard parts list or service documentation calls for it, and verify your unit model and wiring application before ordering to ensure proper fit and correct voltage conversion for your installation.
Please call for available options or find replacement parts.
