Carrier 38BRC060 Limit Switch
This is important 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 heat exchanger that senses, or governs, when the heated air is actually warm enough so that it may be pushed through the ducts and out the vents.
Signals of a worsening main limit switch
- The heating and cooling system will not begin or will not stay running even though max temp has not been reached
- The system is starting to stop suddenly on a regular basis
