Whirlpool ATE1253SPP0 Limit Switch
The limit switch is a type of sensor switch located in the furnace that determines when the heated air is actually warm enough for the main blower to kick in and circulate the air. A limit switch was crafted because if the warmed air is too cool then the house will never get warm enough.
Major indications of an unhealthy limit type switch
- The heating and cooling system will not start nor will it stay running like it is supposed to
- Your system is starting to stop suddenly more than once
