Hi - I had a clogged drain in my standalone upright freezer which led to a neglected ice buildup at the bottom of the freezer, and ultimately blocked the bottom of the door from closing all the way. I've defrosted the freezer and cleared the drain, but the bottom of the door is still not closing flush. (Pls see attached picture.) I've been using strap/clamp to keep the bottom of the door closed (and in the hopes that it would readjust itself), but when I remove the clamp, the gap is still there. Can anyone recommend a solution for this?

thx
