Limit switches were created because if the air is not warm enough the you will lose all the heat as the air flows through the ducts. The limit switch is a type of sensor switch in the heating area that determines when the air is warmed to a point for the blower to be activated.
Key clues of a poorly performing main limit switch
- The HVAC system will not initiate or will not stay running longer than 30 seconds
- The system begins to ramp up but then stops occasionally
