Whirlpool ATR0942SPP0 Limit Switch
The reason limit switches exist is because if the warmed air is too cool then the house will never get warm enough. A normal limit switch has a sensor in the heating area that decides when the heated air is warmed to a point for the main blower to kick in and circulate the air.
Red flags main limit switch should need replacing
- System refuses to start nor will it stay running even though max temp has not been reached
- The system is starting to act weird more often than not
