Bard 8402-165BX - L250-3F Auto Limit Switch
Bard part 8402-165BX is an L250-3F auto limit switch used as a temperature safety control in compatible Bard wall mount and packaged HVAC equipment. It is designed to open the control circuit when a set temperature is reached to help prevent overheating, then automatically reset once temperatures return to a safe range. If you are troubleshooting nuisance trips, no heat, or intermittent blower or heater operation tied to a high limit condition, replacing the limit with the correct Bard OEM 8402-165BX helps restore proper protection and dependable operation. Confirm the exact limit rating and mounting style against your unit model and wiring diagram 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.
