- FAN & LIMIT CONTROL L4064T1830
The Bard 8402-040 fan and limit control (L4064T1830) is an OEM temperature-sensing safety and fan management control used in Bard heating sections to help protect the unit from overheating while also controlling blower operation during a heat call. This style of fan-limit controller uses a sensing element in the warm air stream to open the high-limit circuit if supply air temperature rises beyond the set limit, and it brings the indoor fan on and off based on plenum temperature to support proper heat delivery and cooldown. Use Bard 8402-040 when you need a direct-fit replacement to restore correct heating safety operation and dependable fan cycling, and always match wiring and insertion length to the original control and the unit wiring diagram.
