International Comfort Products PA5542AKA1 Limit Switch
The limit switch has a sensor in the heating area that determines if and when the air is warmed to a point for the air to begin normal home circulation. Limit switches are crucial because if the air never warms up then you will never get hot air through the ducts.
What to see if the limit type switch really is not working right?
- The heating and cooling system will not start nor will it stay running like it ought to
- The whole system starts to ramp up but then stops on a regular basis

Before you decide on buying or purchasing, do your due diligence and double check the model number as well as make a visual inspection in order to be sure the correct limit switch is the one being purchased. There is no need to install the replacement part alone. Search for a pro in your community to pay to install it for you.
