Carrier 50XT-A36 Limit Switch
The limit switch is a switch in the heat exchanger that makes the determination when the heated air is actually warm enough for the air to begin normal home circulation. Limit switches exist because if the air is too cool inside the furnace to begin with, the you will lose all the heat as the air flows through the ducts.
What happens when my limit switch needs replacing?
- The system starts to shut down unexpectedly occasionally
- The HVAC system refuses to start or run well for any length of time

If you decide on picking up or purchasing, do your due diligence and cross-check the model number as well as make a visual inspection in order to be sure the correct limit switch is the one being purchased. HVAC professionals can be expensive so you could call around to find a good deal if money is of great importance to you.
