I bought a RFG297AARS/XAC two years ago, but found last year it has unstable temperature in its fridge. Food and Veg are almost frozed sometime, I use a small thermo to check, found the temperature could change between 0.5 to 6 when I set the temperature to 7 (I set the highest temperature because the temp is usually low in the fridge).
I asked a samsung tech to fix last year, they charge ridiculous, first check they asked for $90, and didn't find a problem but suggest to replace a main board, and next trip, a new board and service charge total in $260. But obviously it was not fixed. And they don't gurantee, now I have to pay them again to have someone check it.
So I hope someone here can help me, I can do some fix if it is not that hard. And could someone send me the service manual please.
