International Comfort Products NDN6100GFA1 Limit Switch
A normal limit switch is a type of sensor switch in the air handler that can determine when the air is actually warm enough to activate the main blower. Limit switches are built because if the air is not warm enough then you will never get hot air through the ducts.
What warnings should I watch out for to know if my chief limit switch is in need of replacing?
- System will not begin the ignition sequence or run like it is supposed to
- The HVAC system is beginning to act weird repeatedly
