    Can blower wheel work when installed backwards

    On service call, high limit keeps cutting out after about 10 minutes , looks like blower wheel might be installed backwards, but the locking nut is on the oposite side of the motor and I can not see or feel the motor side to see if it has 2 locking nuts, although I have never seen one with 2 ,but there is lots of things that I have not seen ,but they exist

    I would think that if it was installed backwards that it would not run that long before tripping high limit, any body run into similar situation??????

    if you have cw wheel on ccw housing then yes it would trip high limit, also check the size of wheel, i came across one where someone had installed wrong diameter, the only way i found problem so soon is because they left old wheel in bushes beside unit. hope this helps

    Yes that helps, Refresh my memory , you determine cw or ccw by looking at motor from shaft end, correct?

    Is it possible to turn wheel around, or must it be replaced, I am thinking replace ???

    Not trying to add fuel to the fire here, but even a real new tech should be able to just look at the blower wheel and determine in 30 seconds or less if the thing is turning or installed the wrong way.

    could be wrong blower wheel, could be reversed motor.

    need to look at housing to see which one.

    thanks for the input, it turned out to be wrong wheel, Motor was original and correct rotation

    looking at them side by side it became clear, I never forget this one, thanks all....
