International Comfort Products T9MPD125L20A1 Limit Switch
One big reason why limit switches are designed that way is because if the air is not warm enough then the house will never get warm enough. A normal limit switch contains a sensor in the heating area that determines if and when the air is warmed to a point for the blower to be activated.
Signals to watch for in a bad limit switch
- The International Comfort Products system starts to run inconsistently on more than one occasion
- Your International Comfort Products system refuses to kick in or will not stay running longer than 10 minutes
