Whirlpool ATR1542BPP0 Limit Switch
Limit switches are crucial due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts. The limit switch has a sensor in the air handler that decides when the heated air is actually warm enough for the main blower to kick in and circulate the air.
Major indications of a declining critical limit switch
- The heating and AC system refuses to kick in or run longer than a minute
- The HVAC system is starting to run erratically on more than one occasion
