the door hinges are tricky to go back in to position hence don't remove as there is no need when just cleaning in between the door glasses.use that guide BUT get 2 people to hold door whilst removing the top screws and separating the door glass as they flip and glass can be dropped.A common call for broken glass due to dropping and cost is HIGH!!!!.Be careful with bottom mountings on glass outer door if plastic as the break off
