This tread sort of sums up my feelings about samsung -
JUNK

Long and short they have questionable reliability PERIOD.
Then when you have an issue they really do not have a Strong Reputation on the ability to Diagnose it or Repair it.
After almost 16 hours of work/diagnoses on my RF18 they declared it Junk. - their words - JUNK!
So because I also spent all that time with them I was able to sort of understand what they were un able to figure out.
In my case Freezer worked - refrigerator not at all - so they replaced the fan - no change - they replaced the board - no change they tested for 4 + hours and determined that the wire to the fan was bad, somewhere in the insulation - Unrepairable - JUNK!
So after another 10 to 12 hours trying to get them to warranty it - all to no Avail.
I went online - ordered a fan - ebay $25.00 - figured I'd work a thermostate into the wiring and hard wire the fan - using an Ice Pick to penetrate the insulation and make it remote - so the fan arrives - and i got all my stuff - wire, thermostat, fan and just before I go out to start the task - the light goes off in my head -
- let's just try the fan - did - it worked - refrig worked - now all is well - spent 120+ days in it last summer with no issues.
Remember samsung declared it unrepairable - JUNK!
That's my Story. Follow the repair tech around ask and learn - it may help.
Best of Luck,
