Icemaker was frozen up. Took it apart and now there is no water coming into the tray. The feeler arm moves but then is stuck about 45 degrees above the horizontal position. Is it possible that the water valve failed? Is there a manual on the Icemaker that shows the position of the feeler arm in relation to the arm thet empties the tray? Thank you Robert A.
