i bought this refrigerator samsung rf27t5501sr. after it was delivered the ice maker is not making ice. samsung sent a repair tech after a week. samsung tech came and reset only the ice maker and gone. the ice maker still not making ice. after another week samsung tech came and replace the ice maker unit. ice maker still not making ice. after another week samsung tech came and did trouble shooting but failed to fix the problem. after another week samsung tech came and did some repairs on the back of the refrigerator. ice maker now is making ice. after another week the ice maker is not making ice again, the fridge and freezer quit cooling. i removed all food inside and throw them away. now i send a request to samsung business center for replacement, but did not get a reply yet.
