International Comfort Products NDN3075HFA1 Limit Switch
A normal limit switch contains a sensor in the heat exchanger that can determine if and when the air is actually warm enough for the blower to be activated. This is important because if the air is not warm enough the you will lose heat in the ducts and the vents will just blow cool air.
Subtle cues of a barely functioning critical limit switch
- The system begins to go through the startup sequence but stops quickly on more than one occasion
- The heating and AC system will not even start or will not stay running even though the desired temperature has not been attained
