4-2-5. If Ice Maker does not operate
1. Water is automatically supplied to the Ice Maker depending on temperature & time condition and Ice Maker
Dispenses cubed or crushed ice.
2. Power is applied to the one end of wires. Be careful when disassembling and shall refer to its exploded
diagram in any case.
3. Ice Maker operation shall be checked after pressing the Ice Maker testing switch.
(Fridge Ice Maker) It is not possible to check when the power is disengaged.
4. We recommend that TWO PEOPLE check the PCB and Ice Maker because they are located at front and rear
side each.
5. Be careful! The Ice Maker Heater can cause personal injury like burn.

Questions and answers
i would like to print page 108 and 115 on the service manual for RF4287 HARS/XAA
the auger motor won't stop runnung. (the dispenser micro switch is working beccause the ice chutes open and close when paddel is pushed)
The auger motor on the Samsung RF4287HARS refrigerator may not stop running due to several possible reasons:
1. Ice Maker Wiring Issue – A wiring problem related to the Q706 movement and auger motor safety could be causing continuous operation.
2. Ice Route Cover – If the COVER ICE ROUTE is not properly closed, it may interfere with motor operation.
3. Ice Mode Selection – If the panel PCB is stuck in Cubed or Crushed Ice mode, the motor may continue running.
4. Cube Motor Position – If the CUBE MOTOR is not correctly positioned at the selected ice mode, it could cause the auger motor to run continuously.
5. MICOM IC01 Malfunction – If MICOM IC01 #103 does not switch to 0V when the ice switch is pressed, it could indicate a control board or switch issue.
Checking these components and connections can help diagnose and resolve the issue.

water pools in the lower freezer and freezes
Water pools and freezes in the lower freezer of the Samsung RF4287HARS due to a clogged or frozen defrost drain. When the drain is blocked, melted water from the defrost cycle cannot properly exit, causing it to accumulate and freeze at the bottom of the freezer. To fix this, defrost the drain by pouring warm water into it until the blockage clears.

the freezer stopped working and about a week later the fridge stopped working error code 1E,39E,14E,25E,
The provided context does not contain definitions for the error codes 1E, 39E, 14E, and 25E. However, it does mention troubleshooting steps for an ice maker sensor issue. To fix a freezer and fridge that stopped working, follow these steps:
1. Check for Error Codes – If the appliance displays an error, consult the manual's troubleshooting section.
2. Reset the Refrigerator – Unplug the unit for a few minutes, then plug it back in to reset the system.
3. Inspect the PCB Connections – Ensure the main PCB connectors are correctly inserted.
4. Check the Ice Maker Sensor – Measure resistance at CN90#1 and CN90#7; if short or open, replace the sensor.
5. Verify Voltage Readings – Measure voltage between CN90#1 (Brown) and CN90#4 (White); it should be between 0.6V and 4.6V.
6. Examine the Wiring – Look for loose or damaged wires and reconnect if needed.
If the issue persists, refer to the refrigerator’s service manual or contact professional service.
