Goodman GKS90904CXAD Limit Switch
A limit switch was crafted because if the air never warms up 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 heated air is warm enough so that it may be pushed through the ducts and out the vents.
Major signs of a failing main limit switch
- Your system begins to become inconsistent repeatedly
- System will not initiate or run longer that five minutes
