Panasonic CU-5E36QBU Limit Switch
The limit switch contains a sensor in the heating area that can determine when the air is warm enough to activate the main blower. Limit switches were created due to the fact that if the air inside the furnace is too cool then you will never get hot air through the ducts.
Clues main limit switch will not live much longer
- The HVAC system will not begin the ignition sequence or will not stay running longer that five minutes
- The Panasonic system begins to shut down unexpectedly time after time

If you are unsure about the correct way of installing the new limit switch on your own then it would be in your best interest to consult a pro to do the replacement of the part.
