Royal Sovereign ARP-9409 Limit Switch
A normal limit switch has a sensor in the air handler that can determine when the air is warm enough for the blower to be activated. This is important due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
Some clues limit switch has to be replaced
- The Royal Sovereign system is starting to initiate and then stops occasionally
- The HVAC system is unable to start or run longer that five minutes
