Bard 8402-020BX - Limit Control 135F/120F

The Bard 8402-020BX limit control is an OEM temperature safety switch used in Bard wall mounted HVAC equipment to help protect the unit from overheating. It is designed to open the circuit at a high limit of 135 degrees F and then reset once temperature drops to about 120 degrees F, supporting safe operation of electric heat and air handler sections where temperature rise must be monitored. If your Bard unit is tripping on high limit or you are replacing a failed safety control during heat kit service, this boxed Bard factory part is the correct fit for restoring original protection and dependable cycling when matched to your model and wiring diagram.

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.
