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. A normal limit switch contains a sensor in the heating area that can determine when the heated air is warmed to a point for the blower to be activated.
Major symptoms limit switch has to be replaced
- System will not begin the ignition sequence nor will it stay running like it ought to
- The system begins to run inconsistently often
