Bard 8406-037BX - 220F manual reset temperature switch

Bard 8406-037BX is an OEM 220F manual reset temperature limit switch used as a safety control in Bard wall mounted HVAC equipment to open the control circuit if an overtemperature condition occurs. When the switch trips, it requires a manual reset after the system cools, helping protect critical components and reduce repeat overheating damage. This is the correct choice when you are replacing a failed or nuisance tripping high limit and you want factory fit and electrical performance that matches Bard specifications. Confirm the original part number on the unit wiring diagram or the existing switch before ordering to ensure proper temperature rating and wiring compatibility.

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.
