Bard 8406-034 is an OEM 170F manual reset temperature limit switch used to protect Bard wall mount HVAC equipment from overheating by opening the safety circuit when a high temperature condition is reached. Because this control requires a manual reset after it trips, it helps ensure the unit is inspected and the root cause is corrected before returning the system to service. If your Bard unit is shutting down on a temperature safety or you are replacing a failed or nuisance tripping limit, matching the 170F rating and the correct Bard part number is the safest way to restore proper operation and maintain factory intended protection.
