International Comfort Products H9MPT100J16B1 Limit Switch
A normal limit switch contains a sensor in the air handler that determines if and when the air is warmed to a point for the air to begin normal home circulation. Limit switches are built due to the fact that if the air inside the furnace is too cool then the house will never get warm enough.
How do you know when your critical limit switch is dying?
- The heating and AC system will not start or will not stay running for any significant length if time
- Your system is starting to runs spotty on a regular basis

If you decide on picking up or ordering do your best and double check the model number as well as make a visual inspection so that you are positive that the correct replacement limit switch is the one being purchased. Some pros may have higher labor rates than others so you may want to ask around to acquire the best rate if you do not want to pay too much.
