International Comfort Products HHP024AKA1 Limit Switch
The limit switch is a switch located in the furnace that decides when the heated air is warm enough for the main blower to kick in and circulate the air. Limit switches were created 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.
What warnings should I watch out for to know if my limit switch most likely is almost dead?
- The whole system begins to act differently repeatedly
- The heating and cooling system refuses to kick in or run well like it should
