International Comfort Products NDN6100GFG1 Limit Switch
Limit switches are crucial because if the air is too cool inside the furnace to begin with, then the house will never get warm enough. A normal limit switch is a switch in the air handler that decides when the air is actually warm enough so that it may be pushed through the ducts and out the vents.
Some warnings to watch for in a failing main limit switch
- The HVAC system is beginning to runs uneven occasionally
- Your International Comfort Products system will not even start or run well like it ought to
