Display shows 46E; ice production is poor or stopped, and ice room temperature may be incorrect.

Safety first: Disconnect power before working in the ice room.

Step 1 – Reset the error:

• Press and hold Power Freeze and Power Cool for 8–10 seconds.
• If 46E returns, continue.

Step 2 – Access the ice room sensor:

• Remove the ice bucket and ice room cover.
• Locate the Ice Room Sensor (often clipped to the wall or duct).

Step 3 – Inspect and test the sensor:

• Check for ice buildup around the sensor; defrost gently if needed.
• Disconnect the sensor and measure resistance with a multimeter; compare to Samsung specs.
• If out of range, replace the sensor.

Step 4 – Reassemble and test:

• Install the new sensor, reconnect wiring, and reassemble the ice room.
• Restore power and verify that 46E clears.

Note: If the error persists with a new sensor, the Main PCB may be faulty and should be evaluated by a technician.
