Bard 8402-131BX - Limit Control Switch
Bard part 8402-131BX is an OEM single-pole limit control used to protect Bard HVAC equipment by opening its switch when temperature rises to its setpoint, helping prevent overheating conditions in the air handler or heater section. This control is commonly specified as a 140°F limit with a 115°F differential and is intended as a direct-fit replacement to restore proper safety shutoff operation when an original limit has failed, drifted out of calibration, or is nuisance-tripping. As with any temperature safety control, confirm the exact Bard model and wiring match before installation and replace any damaged terminals or overheated wiring to ensure reliable operation after the repair.

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.
