Bard 8402-223BX - Limit Control L155-6.0

Bard 8402-223BX is an OEM boxed limit control rated L155 with a 6.0 degree differential, used as a safety temperature switch in Bard HVAC equipment to prevent overheating by opening and closing the control circuit at the specified setpoints. This is a direct-fit Bard replacement part intended to restore proper high-limit protection and reliable heater operation after a nuisance trip, failed control, or out-of-range cycling. Match your existing part number and unit parts list to confirm compatibility, since limit controls can look similar but vary by temperature rating, differential, and mounting style.

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.
