Whirlpool ATR0952BPP0 Limit Switch
A normal limit switch is a type of sensor switch located in the furnace that determines when the heated air is actually warm enough so that it may be pushed through the ducts and out the vents. Limit switches exist due to the fact that if the air inside the furnace is too cool then you will never get hot air through the ducts.
Major signs limit type switch is dying
- The heating and cooling system will not initiate nor will it stay running longer that five minutes
- The HVAC system begins to become unpredictable frequently
