Goodman GME80704BX Limit Switch
The limit switch contains a sensor located in the furnace that decides when the air is warm enough to activate the main blower. Limit switches were created due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
Symptoms of a poorly working critical limit switch
- System will not begin or will not stay running for any significant length if time
- The system is beginning to runs spotty time after time
