Bard 8402-226BX - Limit control switch (L180-8.0)

The Bard 8402-226BX Limit Control (L180-8.0) is an OEM safety temperature limit designed to monitor internal cabinet temperatures on Bard wall mount HVAC equipment and open the control circuit if an over-temperature condition occurs, helping protect the heater and associated wiring from damage. This is a direct-fit Bard replacement control used in the high-limit safety chain, and it is a common fix when a unit is tripping on limit or will not keep heat energized due to a failed or out-of-calibration limit. Match the part number 8402-226BX to your unit model and serial information to ensure proper temperature rating and mounting style before ordering.

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.
