Whirlpool ATR1555CPP0 Limit Switch
A normal limit switch has a sensor located in the furnace that can determine if and when the air is actually warm enough so that it may be pushed through the ducts and out the vents. The main reason limit switches are made is because if the air is not warm enough then you will never get hot air through the ducts.
What are the indications that my chief limit switch is failing?
- The heating and AC system will not start or run well longer than 10 minutes
- Your system begins to shut down unexpectedly frequently
