Carrier 38YCC030 Limit Switch
The main reason limit switches are made is due to the fact that if the air inside the furnace is too cool the you will lose heat in the ducts and the vents will just blow cool air. The limit switch has a sensor in the heating area that can determine if and when the air is warmed to a point to activate the main blower.
What are some indications that my limit switch is crapping out?
- The system begins to runs spotty occasionally
- The heating and cooling system is unable to start or run longer than a minute
