International Comfort Products H8MPT075F14A1 Limit Switch
A normal limit switch contains a sensor in the heating area that determines when the air is actually warm enough for the blower to be activated. Limit switches exist due to the fact that if the air never warms up inside the exchanger then the house will never get warm enough.
Major symptoms to watch for in a bad limit type switch
- The whole system begins to shut down unexpectedly from time to time
- The heating and cooling system refuses to kick in or run even though the desired temperature has not been attained

Before buying or purchasing do your best and cross-check the correct model and also make a visual inspection so that you are positive that the right limit switch is the one being purchased. There is no rule that says you have to replace the part all by yourself. Consult with a professional in your town or city to replace the part.
