Lennox XP19-036 Limit Switch
Limit switches were created because if the warmed air is too cool then the house will never get warm enough. A normal limit switch is a type of sensor switch located in the furnace that determines if and when the air is warm enough for the air to begin normal home circulation.
How do you know when your limit switch is failing?
- System will not begin nor will it stay running longer than 30 seconds
- Your system is starting to runs spotty repeatedly
