Lennox 10ACB Limit Switch
The limit switch is a switch located in the furnace that can determine when the heated air is warm enough for the blower to be activated. 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.
Major signs limit switch has very little life left
- The heating and cooling system is unable to start or continue to run even though max temp has not been reached
- The system is starting to act weird more than once
