Goodman AEPT036 Limit Switch
The limit switch is a switch in the air handler that determines if and when the air is actually warm enough so that it may be pushed through the ducts and out the vents. This is important because if the air is too cool inside the furnace to begin with, then the house will never get warm enough.
Major signs to watch for in a bad critical limit switch
- The whole system is beginning to behave erratically repeatedly
- Your Goodman system will not begin or continue to run like it should
