Payne PA1ZNA048000AAAA Limit Switch
The reason limit switches exist is due to the fact that if the air inside the furnace is too cool then the house will never get warm enough. The limit switch has a sensor in the heating area that determines when the heated air is actually warm enough for the blower to be activated.
Indications to watch for in a failing limit type switch
- The heating and AC system will not start or will not stay running for any length of time
- The Payne system starts to ramp up but then stops from time to time

Before you decide on buying or ordering, do your due diligence and make sure of the correct model as well as make a visual comparison in order to be sure the proper replacement limit switch is being ordered. If you are not sure about the installation of the new limit switch on your own then it is probably best to contact a professional to do the work for you.
