Carrier 50GL048300 Limit Switch
Limit switches exist due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. The limit switch contains a sensor in the heat exchanger that makes the determination when the air is actually warm enough so that it may be pushed through the ducts and out the vents.
Key clues of a poorly working limit type switch
- The heating and AC system refuses to start or run well longer that five minutes
- The system is starting to initiate and then stops occasionally
