Whirlpool ATR1253SPP0 Limit Switch
The limit switch contains a sensor located in the furnace that can determine when the heated air is warmed to a point for the main blower to kick in and circulate the air. Limit switches are built because if the air is not warm enough the you will lose heat in the ducts and the vents will just blow cool air.
What are some indications that my chief limit switch is in need of a replacement?
- System is unable to start or continue to run for any length of time
- The HVAC system is beginning to become inconsistent frequently
