Bard part number 8402-047BX is an OEM automatic limit control used to protect Bard wall-mounted HVAC equipment by opening at high temperature and resetting as the unit cools, with a rated operating range commonly referenced as 180F open and 110F close. This temperature safety switch helps prevent overheating conditions that can damage heaters, blowers, or wiring, and it is a common service replacement when a unit trips on limit, short cycles on heat, or fails to run due to an open safety. For best results, match the exact Bard part number 8402-047BX and confirm the mounting style and wiring connections against your Bard unit model and schematic before ordering.
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.
