Fujitsu AOU18RLXFZ Limit Switch
A limit switch was crafted 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. A normal limit switch is a switch in the air handler that determines when the air is actually warm enough for the blower to be activated.
How do you know when your chief limit switch really needs to be replaced?
- Your Fujitsu system will not initiate or will not stay running even though max temp has not been reached
- The system begins to behave differently often
