Carrier 58STA11010012 Limit Switch
A normal limit switch is a switch in the heat exchanger that makes the determination when the air is actually warm enough for the main blower to kick in and circulate the air. The reason limit switches exist is because if the air never warms up then the house will never get warm enough.
Easy warnings of a defective limit type switch
- The heating and cooling system will not initiate or continue to run for any significant length if time
- The whole system begins to ramp up but then stops more than once
