International Comfort Products NNE100J20G1 Limit Switch
The limit switch is a type of sensor switch located in the furnace that determines when the heated air is warmed to a point for the blower to be activated. This is important due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
Warnings of a weakening critical limit switch
- The heating and AC system will not even start nor will it stay running even though max temp has not been reached
- Your system begins to stop suddenly time after time
