Bard 8402-167 - Limit Switch L170-30/3

Bard 8402-167 is an OEM high-limit temperature control (L170-30, 3 inch element, black/red leads) used in Bard HVAC equipment to help protect the unit by opening the circuit if unsafe temperatures are reached and allowing reset after the temperature drops. This style of limit switch is commonly used in the heat section to safeguard the heat exchanger area and maintain proper system operation when airflow is restricted, filters are plugged, or overheating conditions occur. For correct fit and reliable performance, match the L170-30 rating and sensing length to your unit’s parts list or service manual before ordering, and install it in the factory mounting location with the original wiring connections.
