Bard 8402-148BX is an OEM L325 manual reset limit switch used as a high temperature safety control on select Bard heating equipment, where it helps protect the unit by opening the safety circuit if abnormal heat conditions occur and requiring a manual reset after the issue is corrected. This switch is commonly referenced as a backup limit device and is intended to restore proper safety operation when the original limit has tripped repeatedly, aged out, or failed electrically. For best results, confirm the L325 rating, reset style, and your unit model compatibility before ordering, and replace any underlying airflow, venting, or burner issues that may be causing the limit to trip.
* 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.
