Goodman GKS90703BXAB Limit Switch
The main reason limit switches are made is because if the air never warms up 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 decides if and when the air is warm enough for the air to begin normal home circulation.
What are some indications that my chief limit switch is dying?
- The heating and AC system will not start or run for any significant length if time
- The system starts to run erratically repeatedly
