International Comfort Products NTC6075FBA1 Limit Switch
The main reason limit switches are made is because if the air is too cool inside the furnace to begin with, the you will lose all the heat as the air flows through the ducts. The limit switch contains a sensor in the heat exchanger that senses, or governs, when the air is warm enough for the air to begin normal home circulation.
What are the indications that my critical limit switch is in need of replacing?
- The heating and cooling system will not begin or will not stay running longer that five minutes
- Your system is starting to stop suddenly on a regular basis
