Whirlpool ATR0945CPP0 Limit Switch
A normal limit switch has a sensor in the air handler that can determine if and when the air is actually warm enough that it can be circulated throughout the house. The reason limit switches exist is due to the fact that if the air inside the furnace is too cool then you will never get hot air through the ducts.
Important clues of a failing limit type switch
- The HVAC system is beginning to erratically time after time
- The heating and cooling system will not initiate or continue to run for any length of time
