8402-042 OBSOLETE
- FAN AND LIMIT CONTROL 11"
The Bard 8402-042 fan and limit control (11 inch) is an OEM temperature-sensing control used in Bard heating sections to manage blower operation and provide high-limit safety protection. It monitors plenum temperature to bring the fan on at the proper time and shut it off after the heat cycle, while also opening the safety circuit if abnormal high temperatures occur to help prevent overheating. If you are troubleshooting nuisance limit trips, delayed fan operation, or a blower that does not shut down correctly, replacing the control with the correct Bard 8402-042 helps restore reliable, factory-correct operation. Match the insertion length and temperature settings on your original control and verify compatibility by model and serial number before ordering.
