Bard part 8402-154 is an OEM temperature limit switch identified as L165-30 Exp. Face Auto (orange), used as a safety control in Bard wall mount and packaged HVAC equipment to help prevent overheating by opening the circuit when a set temperature is reached and automatically resetting after conditions return to normal. If your unit is tripping on high temperature or you are replacing a failed limit during a heat service call, installing the correct Bard 8402-154 helps restore proper safety shutoff operation and maintain factory intended control performance. Confirm the temperature rating, mounting style, and wire terminal orientation against your Bard wiring diagram or parts list before ordering to ensure proper fit for your exact model and serial range.
