Bard 8402-209BX - Limit Control L140 4.5 1P
The Bard 8402-209BX limit control is an OEM temperature safety and operating control used in Bard wall mount HVAC equipment to monitor internal temperature and open or close its single pole circuit at a fixed setting. It is commonly identified as an L140 control with a 4.5 degree differential, helping protect the system from overheating while supporting consistent heat operation by cycling the circuit at the designed temperature point. When replacing a limit control, match the part number, temperature rating, and wiring arrangement to your specific Bard model and serial range to ensure proper fit and correct safety function.

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.
