I have a Samsung Refrigerator Model RF23J9011SR/AA Rev. 08 purchased in December 2016 (about 3 ½ years old).
I have a problem where there is frost buildup within the icemaker (see photos). I therefore do a manual (forced) defrost about every 4 to 6 weeks. The procedure I use is:
On the front panel press Freezer (top left) and Cool Select (middle right) buttons simultaneously for about 8 seconds, until there is a “ping” and the display goes blank. Then, press any other button until “Fd” appears (I usually press the Crushed Ice button). Each press selects a different special test mode – “FF”, then “OF C”, then “Fr”, then finally “Fd”. Once Fd is selected it goes into the Forced Defrost mode and will beep for about 25 minutes while it is defrosting. During this period all lights on the front panel are off. At the end the beeping stops, normal lights come on at the front panel, and the refrigerator is back to normal and the frost in the icemaker has melted.
However, when I went through this process 2 days ago, it went into Fd, but after about 10-15 seconds it gave a “ping” sound, the normal lights came on in the display, but the beeping continued for the usual 25 minutes, after which it stopped. However, there had been no defrosting, the frost build-up in the icemaker was still there.
I repeated this 2-3 times with the same results. The only way to stop the beeping after hearing the “ping” (indicating it was coming out of Forced Defrost mode to normal operation) was to power off the fridge.
Here are a few questions:
1. What causes the frost buildup, requiring the forced defrost? My friend has the identical fridge, he does not have this issue.
2. Most importantly, how do I get it to do the manual defrost? Is there some other method to force it? What might have gone wrong?
3. Even better, what can I do to prevent the frost buildup?
Thanks in advance for your help.
