Bard 8402-230BX - 185 Degree Limit Control

The Bard 8402-230BX is an OEM 185 degree temperature limit control used to help protect Bard wall mounted HVAC equipment from overheating conditions by opening the control circuit when the sensed temperature reaches its set point. If your unit is shutting down on high temperature, cycling unexpectedly, or showing heat related faults, replacing a weak or failed limit control with the correct Bard part number helps restore proper safety operation and reliable run time. As a distributor, we recommend confirming the exact model and wiring style in your Bard service literature before ordering, since limit controls must match the specified cutout temperature and mounting for the unit to operate safely.

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.
