What it does / when to replace

The reed switch detects door closed status so the lights, fans and alarms work correctly. Fit a replacement if the light stays on with the door shut, the alarm sounds incorrectly, or cooling behaviour points to a failed door sensor.

• Interior light stays on with the door closed
• Door-open alarm sounds when the door is shut
• Cooling or fan behaviour linked to a failed door sensor

What’s in the pack

• 1 x genuine Samsung reed switch

Fitment & care notes

• Always unplug before work. Confirm DA3400046B / DA34-00046B on your old switch – some Samsung models use a different plunger-style switch.

If you are unsure if this is the correct part, message us with your model or the number on the old part and we will advise.
