Friedrich MW24Y3H Limit Switch
A normal limit switch has a sensor in the air handler that determines when the air is actually warm enough that it can be circulated throughout the house. The main reason limit switches are made 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.
How do you know when your limit switch most likely is not working properly?
- The whole system starts to ramp up but then stops often
- System will not even start nor will it stay running for any length of time
