New Frigidaire FRT125GWK making strange knocking noise

[zubrzubr]

I just purchased a new Frigidaire Model FRT125GWK. It started making a strange knocking noise about 2 days after i plugged it in. It seems to coincide with the compressor running but the noise comes from somewhere else. It is perfectly leveled and it makes the noise even when it's empty. I've tried unplugging it for over 12 hours several times. I recorded a short video of it running from the back. Here's the link:

Any idea what could be causing this?

inside the white box is the defrost timer, that is your noise
i've seen quite a few of them lately that are excessively noisey
the timer on that model only runs when the compressor does making alot of ppl think the noise is from the compressor
