Bard part 8402-232BX is an OEM high-limit temperature control used to protect Bard wall-mount HVAC and heater package assemblies by opening the circuit if the unit temperature rises to an unsafe level. This style of limit control is commonly specified as a one-shot safety device, meaning once it trips it must be replaced to restore proper operation and keep the system protected. Replacing a failed or tripped limit with the correct Bard 8402-232BX helps prevent nuisance shutdowns, overheating conditions, and repeated safety faults, while maintaining the original factory safety sequence. Always confirm the exact temperature rating and wiring terminals match your unit model and serial number before ordering.
* Orders less than $50 may incure a minimum order fee.
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.
