Dang Samsung

[keya81]

I just want to throw this fridge in the garbage, but have invested to much time. I have taken this thing apart and followed all the directions given. After rehooking it, I thought my problem was solved until the whole thing is icing up again with a BRAND NEW HEATER. Grant it I probably am not reading the multimeter correctly when testing the thermo fuse and the sensor. So I’m replacing it this week. Any advice on what else might be causing the problem. I don’t know where the fan is but the one in the back of the fridge is running fine. HELP
