Carrier 52F Limit Switch
One big reason why limit switches are designed that way is because if the air is too cool inside the furnace to begin with, then the house will never get warm enough. A normal limit switch is a type of sensor switch in the heating area that decides if and when the air is actually warm enough for the main blower to kick in and circulate the air.
How do you know if your critical limit switch is on its last leg?
- The system begins to act differently often
- System will not even start or run even though the desired temperature has not been attained
