Carrier 48JZ024040300 Limit Switch
The main reason limit switches are made is because if the warmed air is too cool the you will lose all the heat as the air flows through the ducts. The limit switch contains a sensor located in the furnace that makes the determination when the heated air is warm enough to activate the main blower.
Hints of a poorly performing main limit switch
- The heating and AC system will not start nor will it stay running longer than 10 minutes
- The system is starting to become inconsistent repeatedly
