Has the fan blades slid down the shaft.Should be able to see mark from set screw on shaft if this has happened. I am saying this maybe a possibility since u are having air coming out 5 inches and homeowners have been around it
Blade hasnt slide down the shaft and not running backwards.
piston also correct
Amana tech wants me to change the blade and motor because he said it should be drawing closer to 1 amp and its drawing .6
Sorry for the delay getting back to everyone I really appreciate everyones help thanks
