Carrier 38YCG060 Limit Switch
A normal limit switch has a sensor in the air handler that can determine when the heated air is warmed to a point for the air to begin normal home circulation. Limit switches exist 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.
Easy warnings of a barely functioning main limit switch
- System will not start or run well longer than 10 minutes
- The Carrier system is starting to ramp up but then stops often
