International Comfort Products NTGM075EGA3 Limit Switch
The limit switch has a sensor in the air handler that makes the determination if and when the air is warm enough to activate the main blower. One big reason why limit switches are designed that way 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.
Symptoms of a declining limit type switch
- The system is starting to erratically more often than not
- System is unable to start or run even though the desired temperature has not been attained
