Chances are that the heating element has stopped working allowing frost build up, ice then builds up and freezes into a solid lump, stopping ice production and if you leave it too long will also stop removal of the ice drawer completely. If its still under warrenty get samsung to replace the heating unit for free as they did for me. Or else as I need to do as no longer under warrenty and its broken again, Turn off the whole Frdige every couple of weeks, remove the ice drawer and allow it to defrost. Its a pain but the the only to keep making ice without changing the heating element every 6 months, which is clearly a weak point on the icemaster unit.
I notice my freezer was not holding setpoint when my ice cream was thawed yet the digital display set point was -2 and the actual freezer temperature was 20 (measured with a separate thermometer). The display either did not show the actual temp a few seconds after the -2 setpoint is displayed or it think the freezer is actually -2. NOT!!
Found the same problem with the refrigerator, set point was 36, actual temperature is 40. When I checked the unit first thing in the morning the freezer is 0 (set point -2) and the refrig is 40 (set point 36). Only error code is 88 88 (inverter signal to compressor issue, per samsung Ser Rep but the inverter board red light is steady on, indicating all is normal. So what do I do? I don't think low refrigerant would ever reach 0 degrees, ;but it never reaches setpoint of -2. Obviously the compressor is running. No other error codes. No frozen evaporator, no sensor errors, no temp errors. What do you suggest i do next? Buy a whirlpool?
Thanks, however I don't see anything mentioned on that page about removing the ice buildup. There is no ice at all in the bucket and when I removed it to take a look, I found the ice buildup as pictured above. Thanks!
