Bard 8402-049BX - Limit Control 150 115

The Bard 8402-049BX is an OEM limit control used to protect Bard HVAC equipment by monitoring temperature and opening the circuit if an overtemperature condition occurs, helping prevent nuisance trips and component damage in electric heat and air handling sections. This control is specified as a 150/115 limit, making it a common replacement when troubleshooting units that shut down on high temperature or fail to bring heat back on after cooldown. For best results, match the replacement to your unit’s exact part number and install location, and confirm the temperature rating and wiring connections align with the original control removed from the system.

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.
