Amana BRF20TE bottom freezer - freezer was overfilles and left with door not quite shut - everything was covered with thick frost. Fan began making a buzzing sound when running - sounded like there was frost in the fan. After repacking and getting the door shut the frost cleared after a couple of days but fan still buzzed. I used a hair dryer to try to clear the frost in the fan and result was quiet well-functioning freezer but over a couple of hours the buzz came back, even worse. A couple more tries with the hairdryer with same result - improvement but then it gets even worse. There are a couple of screws on either side of what appears to be a fan cover - I'm considering removing it but if anything drops off befind the fridge it will be a devil of a time getting back there. Any advice?

Unplug the fridge. Remove those 2 screws to remove the cover for the freezer-to-refrigerator temperature adjustment baffle that diverts some of the cold air into the fridge compartment from the freezer compartment -only after there is no ice welding the edges of that cover in place.
Then remove rest of screws on the back and drop the inside back cover forward, but gently - as usually the electrical wire length to the fan is figured at a minimum by the factory, to save money. Tilt it enough to see what is going on and to remove wires from fan to run ohms test of motor and 120 volt test of wire to the fan.
And to inspect and clear out all ice, including down that vent hole, the bottom of the baffle plugs into, that lets cold air in fridge compartment. Make sure that vent is truly clear all the way out into the ceiling of the fridge. Often ice thaws slower than you think it should, even with a hair dryer.
And make sure defrost water can fully drain out the fridge into that cup at top rear of fridge compartment, and run out the drain hose into the pan. Test with some water, or observe if you are doing any thawing, that indeed the water makes it way out to the pan. If it doesn't, water can back all the way up and refreeze, even when your defroster works, and cause problems like you are having.
