Unit was shut down, filled with snow which became ice in front of coil
SOURCE: air conditioner is frozen on the inside
I would shut it off...most A/C's never need to defrost...but I'm not 100% sure about some of the newer models....In my 35 years experience.I have never seen a defrost on anything but a freezer/refrigerator....a humming noise indicates a motor is frozen up...usually a fan motor..in your case it will be the evaporator/condenser fan motor...(your type has a double shaft..that has a fan blade for the evaporator and then another shaft upon which the condenser fan blade is attached...if this goes out it will hum...and it will definitely ice over....and these window units are never supposed to ice over...except when air is not blowing over the evaporator ..or air is not blowing over the condenser. Yes it will continue especially if the fan motor is going bad...and yes keep power to it off..or the compressor can burn out and that IS THE AIR CONDITIONER...if you lose that you may as well buy a new one as the cost of repairs will be more than a new unit.....usually....If you are lucky you can take the cover off an spin the fan blade by hand and try to start it while the blade is spinning to see if it was just stuck...but it may not restart after it stops...if it doesn't you will need a new fan motor. Also next time include the Make and Model #. thanks and good luck...than you for rating my effort...the Fang.

you need to have the unit checked for the amount of freon in the system this must be done with a gauge set the freon amount is obviously incorrect
also the a-frame evaporator must be sealed in the furnace cabinet
SOURCE: icing up of unit
When you clean the Ac unit, Make sure to take the Unit completly out and clean both the condensor coil as well as the Evaporator coil.
If you are able to run the unit with it out of the window. See if there are any service ports connected to the unit (Guage hook ups), or any OIL spots where is looks dark, (Checking to see) if its leaking.
Wasnt sure how you cleaned the unit, So just make sure both coils are cleaned well with water, and make sure to avoid getting to much water into the Electronics.
Good Luck!

SOURCE: Should the LG LS-K-1830CL outdoor unit ice over on
Running the heat pump in low outside ambient temps. will definitely cause the coil to ice up. An ouside temperature senor or a wind baffle should be installed in climates that get below freezing. This would definitely cause the heat pump to operate at lowered efficency and maybe not at all. It should go into defrost mode if the sensor is working correctly when the coil ices up.
SOURCE: icing of the fins of my lg aircondtioner indoor unit
Check/clean intake air filter and condenser fins,as well as be sure condensation drain is clear as well. Sometimes if not the right angle, moisture remains inside unit rather than draining outside, or wherever your drain is, make sure it's clear and draining well.
