Bard 8402-181BX is an OEM limit control (L150-30) used to help protect Bard wall mounted HVAC equipment from overheating by opening the control circuit when a preset temperature is reached, then resetting as the temperature drops by its differential. This boxed replacement is intended to match the original Bard control for proper fit and safe operation, making it a smart choice when you are troubleshooting nuisance trips, no heat issues, or high temperature shutdowns tied to the unit safety circuit. Confirm the L150-30 rating and electrical connections against your unit wiring diagram or service literature to ensure correct application 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.
