Carrier 58CTA15510020 Limit Switch
The reason limit switches exist is due to the fact that if the air inside the furnace is too cool then the house will never get warm enough. The limit switch contains a sensor in the air handler that makes the determination if and when the air is actually warm enough for the air to begin normal home circulation.
Subtle cues of an unhealthy main limit switch
- System refuses to kick in or run like it should
- The HVAC system is starting to behave erratically repeatedly
