Whirlpool ATR0743CPP0 Limit Switch
Limit switches exist due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts. A normal limit switch has a sensor in the heating area that determines if and when the air is warmed to a point that it can be circulated throughout the house.
Indications limit switch will not live much longer
- The HVAC system starts to runs spotty repeatedly
- The HVAC system will not start or continue to run longer than a minute
