• Limit Control L165-7.0 - Boxed

Bard part number 8402-172BX is an OEM limit control (L165-7.0) supplied boxed for service replacement in Bard wall-mounted HVAC equipment. This temperature safety switch is designed to monitor system temperature and open the circuit if the unit reaches its limit setting, helping protect the heater and surrounding components from overheating and nuisance damage. Use it when you have a failed or out-of-calibration limit control causing intermittent shutdowns, no-heat complaints, or safety trips, and always confirm the exact cutout and differential requirements against your Bard model and wiring diagram to ensure correct fit and operation.
