Bard 8407-034BX - 208/240V to 24V Control Transformer
Bard part 8407-034BX is an OEM 40VA control transformer that steps 208/240VAC down to 24VAC to power the low-voltage control circuit in compatible Bard wall-mount and packaged HVAC equipment. A failing transformer can cause no 24V at the thermostat, intermittent control operation, or nuisance shutdowns, so replacing it with the correct Bard-rated transformer helps restore reliable call-for-heat/cool signaling and proper control voltage under load. Verify primary voltage and wiring connections match your unit and confirm the part number against your Bard model and serial information to ensure proper fit and safe operation.

What does the "BX" suffix mean?
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
