Carrier 58DLA09010014 Limit Switch
The limit switch is a type of sensor switch in the heating area that makes the determination if and when the air is warmed to a point for the blower to be activated. Limit switches are built due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air.
Important hints limit switch has to be replaced
- The HVAC system refuses to start or run longer than 30 seconds
- The whole system starts to behave differently more often than not
