Carrier 38YCC042 Limit Switch
The reason limit switches exist is because if the warmed air is too cool then the house will never get warm enough. A normal limit switch is a switch in the air handler that can determine when the air is actually warm enough to activate the main blower.
What happens when my limit switch is not working right?
- The system begins to behave erratically repeatedly
- The HVAC system is unable to start or will not stay running even though max temp has not been reached
