Carrier 48SS 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 you will never get hot air through the ducts. The limit switch is a type of sensor switch located in the furnace that makes the determination if and when the air is warmed to a point that it can be circulated throughout the house.
Key signs of an inadequate limit switch
- The HVAC system is starting to act differently repeatedly
- The heating and AC system will not start or run well even though the desired temperature has not been attained
