Lennox CBX27UH-060 Limit Switch
One big reason why limit switches are designed that way is because if the warmed air is too cool then the house will never get warm enough. The limit switch has a sensor located in the furnace that senses, or governs, when the air is actually warm enough for the air to begin normal home circulation.
Signs critical limit switch is on its last leg
- The heating and cooling system will not even start or will not stay running as it should
- Your system is starting to ramp up but then stops on a regular basis
