Ice sensing lever (keyed onto mtr shaft) found down and would not budge. Also, test button (hidden beneath mtr) only 'beeped' when pushed. The 10 pin connector's 'clip' is also hidden against roof of freezer - mine broke but connection still seems secure. New unit was exact fit - test button (now) cycles thru one cycle of rotation and H2O fill with no beeps.... 18 hrs later, bin is half full....ice for the summer :)
Remove freezer door (front) so you can lay down and look up. Cold plastic was worrisome but fit was exact - no issues except connector.
