I have frequent ice build-up on the pipe that comes out of the compressor.
After a while (I assume when the fridge is defrosting) it will either thaw, or whole chunks of ice will drop off. Either way, they will both end up on the floor underneath the fridge, leaving me with a puddle.

Is this normal, and if not (actually, even if it is), is there anything I can do about it (apart from putting a tray underneath)?

I just checked, and they all look fine (just a slight layer of frost on them).
Also, the fridge itself works normally. Temperatures are where they should be, and no frost build-up anywhere else.
It's just that pipe in the back — and it's more of an annoyance than a functionality issue, having to deal with the drippage on the floor.

What Reg meant was that WE need to see a picture of the evaporator frost pattern. You can attach a photo here.

Is the fan inside the freezer running?

Has the sealed system (compressor, associated tubing, and refrigerant) been worked on lately?

frosting back to the compressor on the suction line is a sure-fire sign of a refrigerant overcharge..

yeppers, just had an inflated look at your photo and sure enuff...someone has sweated schrader port on that low side process tube...

"just put some more freon in there Pierre...if some is good , more has to be better!"

The fan next to the evaporator coil is running fine, and no work has been done on the sealed system for as long as I had the fridge (for about 4 years).
The unit was bought used, so I don't know what had been done to it before.

Attached is a picture the evaporator coils.

Image didn't upload with the last message, so we'll try it once more...

We changed it so they can because it's such a great way to faciltate problem descriptions. B)

Ok,your frost pattern looks good...I still stand by the over charge theory...this is an older box...possibly R12 freon.

Nice work boss...a helpful change...nice!

So I guess a tray underneath is my only solution after all? ;)

I don't wanna be the one to suggest that you let some of freon out...so I wont...
another option may be to insulate the line with armaflex foam rubber insulation...

If this for sure wasn't happening in the prior 4 years of you owning the unit then it very well could just be a separated heat exchange but that is quite a bit of frost back for just a separated heat exchanger.
