GE AZ75E18EACM1 Limit Switch
A normal limit switch is a type of sensor switch in the heating area that determines when the air is warmed to a point for the air to begin normal home circulation. The reason limit switches exist is because if the warmed air is too cool the you will lose heat in the ducts and the vents will just blow cool air.
Cues of a weak critical limit switch
- The HVAC system is unable to start or continue to run for any significant length if time
- The GE system is beginning to go through the startup sequence but stops quickly often
