LG LMU180HE Limit Switch
The limit switch is a switch in the heat exchanger that makes the determination when the air is warmed to a point for the blower to be activated. A limit switch was crafted due to the fact that if the air inside the furnace is too cool then the house will never get warm enough.
What warnings are present when my main limit switch is almost dead?
- The LG system begins to run inconsistently more often than not
- The HVAC system will not even start nor will it stay running as it should

If you decide on picking up or ordering, do your due diligence and double check the model number as well as make a visual inspection so that you are positive that the proper replacement limit switch is the one being purchased. You do not need to install the part by yourself. Locate a pro in your town or city to do it for you.
Feel free to download your manual for help.
