Whirlpool ATR0742BPP0 Limit Switch
Limit switches are built because if the air never warms up the you will lose all the heat as the air flows through the ducts. A normal limit switch has a sensor located in the furnace that determines when the heated air is warm enough for the main blower to kick in and circulate the air.
What are some indications that my chief limit switch is in need of replacing?
- System refuses to kick in nor will it stay running like it ought to
- The system begins to runs uneven time after time
