Samsung AVMWC052EA0 Limit Switch
A normal limit switch is a type of sensor switch in the air handler that makes the determination when the heated air is actually warm enough to activate the main blower. The reason limit switches exist is due to the fact that if the air inside the furnace is too cool the you will lose all the heat as the air flows through the ducts.
What are some hints that my limit switch is almost going bad?
- The heating and AC system refuses to start or run well as it should
- The system is starting to shut down unexpectedly occasionally

Before you decide on buying or purchasing, do your due diligence and cross-check the model number as well as make a visual inspection so that you are positive that the correct limit switch is the one being purchased. If you are not sure about installing the new limit switch by yourself then it may be wise to contact a professional to do the replacement of the part.
