Bryant 120 Limit Switch
One big reason why limit switches are designed that way is due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. A normal limit switch is a type of sensor switch in the heat exchanger that determines when the heated air is warmed to a point for the blower to be activated.
What red flags are there that my limit switch most likely really needs to be replaced?
- The whole system starts to run erratically repeatedly
- The heating and AC system will not even start or continue to run like it ought to
