Goodman GCH90905DX Limit Switch
Limit switches are built due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough. The limit switch has a sensor located in the furnace that can determine if and when the air is warmed to a point that it can be circulated throughout the house.
Signs to watch for in a bad limit type switch
- Your system begins to act differently repeatedly
- System will not start nor will it stay running for any significant length if time
