International Comfort Products GNK075N14A3 Limit Switch
The reason limit switches exist is because if the air never warms up then you will never get hot air through the ducts. The limit switch has a sensor located in the furnace that decides if and when the air is warm enough that it can be circulated throughout the house.
What are some indications that my main limit switch has to be replaced?
- The heating and AC system refuses to start nor will it stay running longer that five minutes
- Your system is beginning to runs uneven time after time
