Lennox XC13-060 Limit Switch
Limit switches exist because if the air never warms up then you will never get hot air through the ducts. A normal limit switch contains a sensor in the heating area that decides when the air is warmed to a point that it can be circulated throughout the house.
What to see if the limit switch is not working properly?
- The heating and cooling system is unable to start or will not stay running like it ought to
- The HVAC system is beginning to behave differently occasionally
