Whirlpool ATR1252BPP0 Limit Switch
Limit switches are crucial due to the fact that if the air never warms up inside the exchanger the you will lose heat in the ducts and the vents will just blow cool air. A normal limit switch has a sensor in the heat exchanger that decides if and when the air is actually warm enough that it can be circulated throughout the house.
Indications critical limit switch is on its last leg
- The heating and AC system will not even start nor will it stay running even though the desired temperature has not been attained
- The Whirlpool system is beginning to become inconsistent on more than one occasion
