Edgestar AP8000W Limit Switch
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. The limit switch has a sensor in the heating area that decides when the heated air is warm enough for the main blower to kick in and circulate the air.
Major symptoms critical limit switch is going to die
- The heating and AC system will not start or will not stay running like it is supposed to
- The system begins to go through the startup sequence but stops quickly on a regular basis
