Whirlpool ATR0945RPP0 Limit Switch
Limit switches are built because if the air never warms up the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch is a type of sensor switch in the heat exchanger that makes the determination when the heated air is warm enough for the main blower to kick in and circulate the air.
Easy warnings of a declining limit switch
- Your Whirlpool system will not start or run well longer than 30 seconds
- The system is starting to become inconsistent frequently
