Bard 8402-157 is an OEM manual reset limit control rated at L175, used as a high temperature safety switch in Bard HVAC equipment to shut the unit down if temperatures rise beyond the control point. When the limit trips, it must be manually reset, which helps prevent repeated overheating and protects key components during abnormal airflow or heating conditions. This replacement is a direct-fit Bard control intended to restore proper safety operation, so match the part number to your unit model and the original limit rating before ordering.
* Orders less than $50 may incure a minimum order fee.
