Head section will not go up or down
Equipment: Hill rom p1400 centra
you've tried it from both siderails?
unplug the left side rail and try the controls from the right, then vice versa.
Is it still not working from either?
are you hearing any noise from the motor?
disconnect the head motor(left side when standing at the head end), check to see if any voltage is coming to the motor when pressing the up or down switches
