Bard 8402-084BX - Auto limit switch
The Bard 8402-084BX is an OEM auto limit control used in Bard wall mounted HVAC equipment to help protect the electric heat section from overheating. This temperature safety switch opens on high temperature and automatically resets when conditions return to normal, helping prevent nuisance shutdowns while maintaining safe operation. If you are troubleshooting a heater that cycles off on limit, runs briefly, or shows heat fault symptoms, replacing a weak or out of calibration limit with the correct Bard 8402-084BX is a smart first step. Always match by exact part number and verify the mounting location and wiring connections against your Bard unit wiring diagram before installation.

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.
