I have a Maytag MQU2057AEW, that forms ice at the bottom every day and also puddle a little in front on the floor. --- I have looked at a parts diagram and it shows a drain plug in the bottom of the floor of the inside of the freezer. However, I have looked several times and I do not see a drain plug or hole. It seems like a drain plugged up but I can not find one. Thanks

I believe you will have to remove the back panel in the freezer section to find the drain. It will be in the evaportator pan.
