Opened mailer and bag and place the drain plug into the drain. fit perfectly. In fact it is better than the one lost since the original needed a screwdriver or tool to remove the plug. This one has a flang or finger turner on it so that it can be removed. Also, does not interfere with items in bottom of freezer.
removed the main screw to expose the cold control, checked for power at the 2 power terminals. no power. ordered new control and resolved the problem. easiest repair I have ever done.
