Blowing dusty air from the vacuum (I know the type you mean, though it isn't the type I have) sounds iffy for a food storage unit. The hair dryer does much the same thing with cleaner and warmer air. Directing the hot air to the crevices between the freezer compartment and the larger box is enough that the large pieces of ice eventually fall off. The goal wasn't to melt it all in place, it was to dislodge the chunks. And to be patient. If you try prying ice chunks loose with anything too sturdy (screw driver, etc.) you can pierce the aluminum and kill the fridge. We're talking a vintage handheld Vidal Sassoon Quiet Styler, not a bouffant cap or something less directed. :)

Continuing with baking fancy breads this morning, baking in small pans so I have several small loaves instead of cutting slices from a large loaf.
