Samsung rs2555sl icemaker

If the freezer is cold enough and the icemaker is cycling that only leaves the inlet valve. replace the valve and enjoy the ice.
If the freezer is cold enought and the icemaker does not cycle, then you have a bad icemaker. Simply replace the icemaker and viola.

TOOLS NEEDED:
Eyes (fair to good shape)
#2 phillips screw driver
Flashlight

Lets assume it was working at one time right? And the FREEZER temp is BELOW 20degs

REMOVE storage bin to see icemaker.

LOCATE test button on underside or rightside of clear motor asembly.
(should be black)

Press until icemaker starts, then release button. Watch the tray twist and return to upright the should fill with water.

If icemaker worked: ICE SENSOR MAYBE BAD> ORDER NEW ICEMAKER IF THE ICE DOES NOT EJECT AFTER 4

If icemaker did not Start by pressing the test button.: UNPLUG the frig or go the Main Service Panel to the house (BREAKER BOX) and shut off the power and verify NO LIGHTS INSIDE THE FRIG>

Remove the concealed screws holding the icemaker to the ceiling.

PULL the icemaker forward to release icemaker. Using the Flashlight
LOCATE the wiring harness on the ceiling. Look for the RELEASE and Squeeze and pull down. Inspect the electrical pins to make sure all pins are equal and secured. If all is well there?
THE PROBLEM COULD BE either: ICEMAKER or Main PC Board

I would order a Icemaker assembly first since it is the least expensive.

Your Welcome

Your icemaker sensor is out of its place. unplug the unit . check bottom of your icemake, the sensor looks like a little ***** , insert it back. turn unit on, and reset the board, Hold power freez, Power Cool for about 10 seconds.

CHECK PWR TO UNIT, CHECK MAIN PANEL BREAKER FUSE IF GOOD , CHECK BIN SENSOORS AN WATER PUMP

Samsung Fridge  RS2545SH stopped cooling. The fridge section is about 50/55 and freezer is around 45. It wont go below. At one point, there was rumbling rattling sound from the compressor. Icemaker also stopped woprking.

unfortunately it sounds like you have a broken tooth on the drive or driven gear of the ice maker, in this case you should replace the ice maker. The good news is that you can get a new one for about 85 bucks at your local appliance parts store.

it could that your thermostat is set too cold making the ice crack and brittle

Did you ever get any advice for this problem? Please repost if not.
