Carrier 58DLX11010022 Limit Switch
A normal limit switch has a sensor in the heating area that can determine when the heated air is actually warm enough for the blower to be activated. Limit switches are built because if the air is not warm enough then the house will never get warm enough.
What warnings should I watch out for to know if my critical limit switch is almost dead?
- System refuses to kick in nor will it stay running longer than 30 seconds
- The HVAC system is beginning to ramp up but then stops occasionally
