Whirlpool ATE1245CPP0 Limit Switch
One big reason why limit switches are designed that way is because if the air is not warm enough then the house will never get warm enough. The limit switch contains a sensor in the heat exchanger that senses, or governs, when the air is actually warm enough for the blower to be activated.
Major indications of an ineffective critical limit switch
- The heating and cooling system will not begin or will not stay running longer than 30 seconds
- Your system is beginning to stop suddenly more than once
