Tried pushing drawer in it had no effect on the flashing light. It appears that on closer inspection I had lost the magnet on the drawer, which was causing the problem all a long. Did not know that the silver section in the centre of the drawer front was in fact a magnet. Currently have other drawer in place and ice maker working fine.
Thanks for your help, have ice back again and did not have to purchase and expensive ice tray. Only need to find supplier for new magnet, or move the one from the other drawer.
