Carrier 58DLA11010022 Limit Switch
A normal limit switch contains a sensor in the heating area that senses, or governs, when the air is actually warm enough for the main blower to kick in and circulate the air. A limit switch was crafted because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts.
Clues of a worsening main limit switch
- The whole system is beginning to run inconsistently repeatedly
- The heating and cooling system refuses to start or run longer than a minute
