A normal limit switch is a switch in the air handler that can determine if and when the air is actually warm enough that it can be circulated throughout the house. Limit switches were created because if the warmed air is too cool then you will never get hot air through the ducts.
Some clues limit switch will need replacing
- The heating and AC system will not initiate or continue to run longer than a minute
- The HVAC system is starting to stop suddenly repeatedly
