Bard 8402-180 is an OEM limit control (L140-30) used on select Bard wall-mounted gas electric equipment to help protect the heat section from overheating by opening the safety circuit when temperatures rise beyond its setpoint and automatically resetting as conditions return to normal. If your unit is tripping on limit or you are replacing a failed high limit during a no-heat diagnostic, installing the correct Bard safety limit is important for proper burner operation, safe cycling, and preventing nuisance shutdowns. Match this part to the exact model and serial information on your Bard unit and confirm the original limit rating and wiring style before ordering to ensure proper fit and function.
* Orders less than $50 may incure a minimum order fee.
