International Comfort Products GDE100F14A1 Limit Switch
Limit switches were created due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts. The limit switch is a switch in the heating area that determines when the air is actually warm enough for the main blower to kick in and circulate the air.
What happens when my chief limit switch is not working right?
- System will not begin the ignition sequence or will not stay running like it should
- The system is starting to act differently frequently
