Hi, I have an open circuit component from the controller board to the 120v power switch. It looks like a 1/2 watt resistor green body marked 7A LE. The "E" is in the legs of the "L" so probably a manufacturers ID. I think it may be a fuse, thermal or inductor. Your opinions may help.
I have a photo, but don't know how to attach it to the problem. Thanks, John.
