• Limit Control 150-115 Line Break

Bard part number 8402-056 is an OEM limit control used in Bard wall mounted HVAC equipment to monitor temperature and open the circuit if the unit reaches its safety limit, helping prevent overheating and nuisance shutdowns. The 150-115 line break rating indicates a temperature based operating range commonly used for high limit protection in heater and airflow related safety circuits. Replacing a weak or out of calibration limit control can resolve intermittent heat loss, unexpected cycling, or safety lockouts when the rest of the system is operating normally. For proper fit and safe operation, match the original control style and temperature markings from your unit and confirm compatibility by model and serial number before installation.
