Lennox XP14-060 Limit Switch
A normal limit switch is a switch in the heat exchanger that decides when the heated air is actually warm enough for the blower to be activated. This is important because if the air is not warm enough then you will never get hot air through the ducts.
Elements poorly running limit type switch
- The HVAC system is starting to behave erratically occasionally
- The HVAC system will not initiate or continue to run even though the desired temperature has not been attained
