International Comfort Products TCA024AKA1 Limit Switch
Limit switches were created due to the fact that if the air never warms up inside the exchanger the you will lose all the heat as the air flows through the ducts. The limit switch is a type of sensor switch in the air handler that makes the determination if and when the air is actually warm enough for the blower to be activated.
What happens when my main limit switch is in need of a replacement?
- The heating and cooling system will not even start or will not stay running longer than 10 minutes
- The system is beginning to behave differently occasionally
