Whirlpool ATE0942BPP0 Limit Switch
A normal limit switch is a type of sensor switch in the heat exchanger that makes the determination when the heated air is warmed to a point for the blower to be activated. Limit switches are built because if the air never warms up then you will never get hot air through the ducts.
What are the signs that the main limit switch has to be replaced?
- The system is beginning to stop suddenly occasionally
- Your Whirlpool system will not even start or continue to run for any significant length if time
