Panasonic CS-KS18NB4UW Limit Switch
Limit switches are built because if the air never warms up then the house will never get warm enough. The limit switch is a type of sensor switch in the heat exchanger that senses, or governs, when the heated air is warm enough to activate the main blower.
Major symptoms of a failing critical limit switch
- The system begins to run erratically more than once
- The heating and cooling system refuses to start nor will it stay running for any significant length if time

Before you decide on buying or ordering do your best and cross-check the correct model as well as make a visual inspection so that you are positive that the correct limit switch is being ordered. There is no rule that says you have to install the replacement part alone. Find a professional in your town or city to do the job for you.
