International Comfort Products NAC260AKA1 Limit Switch
The limit switch has a sensor in the heating area that can determine when the heated air is warm enough to activate the main blower. The main reason limit switches are made is due to the fact that if the air inside the furnace is too cool then the house will never get warm enough.
Important hints limit switch will need replacing
- The whole system is starting to act differently occasionally
- The heating and AC system will not start or will not stay running like it should
