Carrier 38EYG036 Limit Switch
A normal limit switch is a type of sensor switch located in the furnace that decides when the air is warmed to a point to activate the main blower. One big reason why limit switches are designed that way is because if the air never warms up the you will lose all the heat as the air flows through the ducts.
What happens when my limit switch is in need of a replacement?
- System refuses to start or run like it ought to
- The Carrier system starts to run inconsistently on a regular basis
