Whirlpool ATR1552SPP0 Limit Switch
The reason limit switches exist is due to the fact that if the air inside the furnace is too cool 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 located in the furnace that determines when the heated air is warmed to a point for the air to begin normal home circulation.
Major clues limit type switch should need replacing
- The heating and cooling system will not start or will not stay running like it ought to
- The HVAC system starts to behave differently on a regular basis
