Whirlpool ATE1243SPP0 Limit Switch
One big reason why limit switches are designed that way is because if the air is not warm enough the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch is a switch in the air handler that can determine when the air is warm enough so that it may be pushed through the ducts and out the vents.
Key indicators that my limit switch is in need of a replacement?
- Your system starts to behave differently on more than one occasion
- The heating and cooling system will not even start or run like it ought to
