Excessive frosting building up quickly around the lid on my 5 year old Norfrost Aura top-opening frezeer. I do not know the capacity, but the outside dimensions are 54x54x84mm. The control is set at 60% towards max. No other specs, re model number, etc. visible.

There is normally a drain plug on the lower rear or sides. You probably have leaking door gasket.

If your LG freezer is suposed to be "frost free" it may have a blocked defrost water outlet.

This freezer is not frost free. Being an upright limiting the amount and frequency of opening the door will reduce the build up of ice. Ice is expected and depending on humidity and quality of seal around door affects the amount of ice.

Using a thin ribbon check the seal integrity around the door. Confirm nothing is prohibiting the full closure of the door.

Adjust door if necessary. Replace seal if defective. Freeze open unsealed items in a frost free freezer before locating frozen food in this unit.

These units are likely located in the garage where the humidity is high. If used only as needed planning transfer between this and the kitchen unit frost can be minimized.

Being a conventional freezer not frost free freezer burn is less likely and frozen food will not dry out as quickly. Confirm that the freezer maintains about 0 degree F.

This unit is likely more efficient and will maintain the food frozen longer in the event of power outage.

Hope this helps?

Going to have to assume a lot of things... because you put no make or model... (such as self defrosting).

After you have checked that there is NOT excessive FROST BUILD UP (prevents air flow & causes same symptoms...
(defrost issue: different trouble ... comment me back)

Without any mention of EXCESSIVE FROST (which would indicate poor door seal/alignment...
(Not DEFROST FAILURE (dry defrost pan)...

That leaves us with your EVAP FAN...

There are a couple of reasons evaporator fans fail:

(you just eliminated old age in your question... "year old")

- Defective is still a possibility (replace)

- Ice/frost blocked (Full manual DEFROST)

- Physical blockage ((inspect: usually wire or POOR install.

Check your manufacturer's parts list and shop around for the BEST PRICE... There NO variances in quality (just price).

GOOD freezers work because of excellent air flow...!!

And ALWAYS REMEMBER TO TAKE PICURES & REMOVE POWER BEFORE fiddling with every appliance.

Good luck...

start with a spirit level and ensure the freezer is level all round (with the lid up.)if the feet are not adjustable, use spacers,then close the lid and if you have to,use a hot wet cloth to mould the seals to fit correctle(flat to frame) check with a thin piece of paper to ensure no air leaks.do this before you try to adjust the hinges,

The defrost circuit has failed. Typical failures are the defrost heater has opened, the defrost timer if equiped, is not advancing or the defrost thermostat is open. To check the heater, melt the ice, and use a meter to check if the heating elements are open, if they are, then you will need to replace the heating element.

Funny. We just spent an hour trying to figure out the same problem with our Kenmore. It is the third or fourth time that we've noticed water on the floor under the freezer, but the first time that we've been able to track it to the lid.

The only thing that makes sens to me is that this problem may be happening when our freezer has a frost buildup around the top of the unit which doesn't allow the lid to close perfectly snug. I'm thinking that this causes a bit of melt in whatever frost may be inside the lid from regular air circulation around the unit. It runs out the back of the lid when it opens.

Check that there is no frost around the rim of the freezer that may be causing a slight (it only takes a very small opening to allow warmer air to circulate under the lid) irregularity in the lid seal.

The freezer is probably in need of defrosting. This usually occurs when the freezer has been over packed. It needs to be able to ahve air flow through it, there are holes in the back of the freezer and a defrosting element at the top and they need to be clear in order to keep it frost free. It happend to me and we called an engineer out. solved it by using hair dryer to defrost it.

your compresor is hot but is it running at all or is it just humming trying to start and the just clicks off if it is just your overload that is tripp you need to replaced it that the box connected to the compressor on the left side that is why not is cooling if is running then is cheaper to buy a new one since the 5 year warranty on the compressor has expired

An upright freezer that is not frost free will have the coils in the shelves (shelves are non-removeable) and that is where the frost will buildup.  If your model is like this then it will have to be defrosted periodically.  If your not sure then give me the entire model # from the sticker inside the freezer and I will look it up for you.
