Some warnings critical limit switch is dying
- The HVAC system begins to runs uneven more than once

If you decide on picking up or purchasing, do your due diligence and double check the correct model and also make a visual comparison so that you are positive that the proper replacement limit switch is the one being purchased. You do not need to install the replacement part alone. Search for a pro in your town or city to do it for you.
