Carrier KFCEH1901C20 Limit Switch
The limit switch is a switch in the air handler that can determine if and when the air is warmed to a point so that it may be pushed through the ducts and out the vents. One big reason why limit switches are designed that way is because if the air never warms up the you will lose heat in the ducts and the vents will just blow cool air.
Major warnings limit type switch needs replacing
- The whole system begins to ramp up but then stops on more than one occasion
- The HVAC system will not start nor will it stay running longer than a minute
