Bard part 8406-027 is an OEM manual reset safety switch used in Bard wall mounted HVAC equipment to open the control circuit when an abnormal condition trips the switch, helping protect the unit from damage and nuisance repeat cycling. Because it requires a technician to manually reset it after the underlying issue is corrected, it is commonly used where a positive service acknowledgement is needed before the system can restart. This Bard OEM replacement is the right choice when you are troubleshooting a unit that will not run due to a tripped safety or when the original switch has become unreliable, and matching the exact part number helps ensure proper fit and correct control function across compatible Bard models.
* Orders less than $50 may incure a minimum order fee.
