💡 Pro Tip: How to Know Your Door Lock Switch Is the Problem

Your part is likely the culprit if you notice any of the following:

⚠️ Washer fills with water but the drum won't start agitating or spinning

⚠️ Door feels unlocked or loose even after the cycle starts

⚠️ Control panel displays a door lock error code (dL, dE, or similar)

⚠️ Washer stops mid-cycle and door unlocks unexpectedly

🔍 Diagnostic Tip: Unplug the washer, remove the top panel to access the door lock assembly, and test the lock solenoid terminals with a multimeter for continuity. No continuity = failed lock — replace with DC34-00025B. Always unplug before testing.

Questions & Answers

What part numbers does DC34-00025B replace?
Answered by Support Team  ·  Mar 15, 2024
DC34-00025B directly replaces AP5799391, PS8763546, and 3990149. These are all cross-reference numbers for the same Samsung washer door lock switch assembly. Always verify your model number before ordering.
Which Samsung washer models is DC34-00025B compatible with?
Answered by Support Team  ·  Nov 20, 2023
DC34-00025B is confirmed compatible with Samsung BabyCare top-load washer models WB09H7300GP/A1 and WB09H7300GW/A1. If you have a different Samsung washer model, please check your model number against the part compatibility list or contact us before ordering.
What voltage does the DC34-00025B door lock switch operate at?
Answered by Support Team  ·  Jan 8, 2025
The DC34-00025B operates on DC 12V via a motor-driven latch mechanism. This is consistent with Samsung's design for this BabyCare washer platform and matches the original OEM specification exactly.
Is this an OEM part or an aftermarket replacement?
Answered by Support Team  ·  Jul 22, 2024
This is an aftermarket (non-OEM) replacement part manufactured to OEM specifications. It is not made by or endorsed by Samsung, but is designed to be a functional equivalent of the original DC34-00025B at a lower price point. It uses the same DC 12V motor-driven design and the same connector and mounting footprint.
My washer shows a door lock error code but the door physically closes — does that mean the lock switch is bad?
Answered by Support Team  ·  Feb 10, 2026
Yes, that is a common symptom of a failing DC34-00025B door lock switch. Even if the door closes and feels snug, the internal lock solenoid or micro-switch contacts can fail electrically while the mechanical latch still engages. You can confirm by unplugging the washer, removing the top panel, and testing the lock solenoid terminals with a multimeter for continuity. No continuity means the lock switch has failed and should be replaced.
