Carrier 38E Limit Switch
This is important 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. A normal limit switch contains a sensor located in the furnace that senses, or governs, when the air is actually warm enough to activate the main blower.
Easy warnings to watch for in a failing critical limit switch
- The heating and cooling system will not initiate or run well like it should
- Your system starts to behave differently time after time
