Samsung side-by-side not cooling (2004)

The frige and freeze do not stay cold.
The ice door keeps making a clicking sound and the fan (but not compressor) keeps kicking on and off.
I replaced the front control panel, but the problem remains so the old front panel is back on.

I have unpluged it and let it set open for 24 hours and then replugged it back in and for the first minute it seems to operate fine: the front board illuminated; the compressor kicked on, however after a minute of running - the ice door starts cycling over and over and the front panel flashes and goes off. Then the number 3 appears and the panel comes back on and the process repeats itself until I unplug it.

Is there anyone that can help me run some disgnostic on this (i don’t know how to run the tests) and walk me through a fix for this.

This is the third time this has happened - the first two times was when it was under warranty (a couple of years ago) and the service came out and replaced the front board/panel.
