Carrier 50ZP-042 Limit Switch
The limit switch is a switch in the heat exchanger that determines when the air is actually warm enough so that it may be pushed through the ducts and out the vents. One big reason why limit switches are designed that way is due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts.
Warnings limit type switch is on its last leg
- The whole system begins to initiate and then stops time after time
- The HVAC system will not even start or will not stay running longer than a minute

If you decide on picking up or ordering, do your due diligence and make sure of the model number and also make a visual comparison in order to be sure the proper replacement limit switch is the one being purchased. The installing of a new limit switch is a piece of cake provided you have the time and have the tools to get it done.
