International Comfort Products T9MPT075F12A1 Limit Switch
A normal limit switch is a switch in the air handler that determines if and when the air is actually warm enough so that it may be pushed through the ducts and out the vents. The main reason limit switches are made is due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
What warnings are present when my chief limit switch is not working properly?
- The whole system is starting to act weird on more than one occasion
- System is unable to start or run longer than 30 seconds
