The Bard 8402-206 is an OEM limit control (L140-30, 1 pole) used in Bard HVAC equipment to help protect the unit from overheating by opening the circuit at its temperature limit and resetting as temperatures return to normal operating range. This temperature safety control is commonly associated with gas/electric wall-mounted Bard systems where maintaining correct high-limit operation is critical for safe heat performance and proper shutdown under abnormal conditions. When replacing a failed or nuisance-tripping limit, match the original temperature rating and mounting style to your unit documentation to ensure correct fit and reliable operation.
