Bard 8402-139 - Limit Control L185-80

Bard part 8402-139 is an OEM limit control (L185-80) used to help protect Bard wall-mounted and other Bard HVAC equipment by monitoring temperature and opening the circuit if the system reaches an unsafe condition, helping prevent overheating and nuisance damage. In the field, this style of limit control is commonly used in the heater/air stream safety chain, and replacing a weak or intermittently tripping limit with the correct Bard specified control helps restore reliable operation and proper safety shutdown behavior. Always confirm the exact temperature ratings and reset style required for your specific unit and serial number, then install using the original wiring positions to maintain proper control sequence.
