Carrier 58CTA04510008 Limit Switch
Limit switches are crucial because if the air is not warm enough then you will never get hot air through the ducts. The limit switch has a sensor located in the furnace that senses, or governs, if and when the air is actually warm enough for the blower to be activated.
Major clues of a barely functioning main limit switch
- The Carrier system begins to shut down unexpectedly occasionally
- The heating and AC system will not start nor will it stay running longer than 30 seconds
