International Comfort Products TCH448AKA1 Limit Switch
The limit switch is a switch in the heating area that determines when the heated air is actually warm enough for the main blower to kick in and circulate the air. Limit switches were created due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough.
Easy warnings main limit switch should need replacing
- The HVAC system starts to behave erratically from time to time
