Samsung Front Load Washer Door Lock Switch Parts — Models & Compatibility

Your Samsung front load washer won't start, and you notice the door isn't clicking locked like it used to. That's typically the door lock switch failing — one of the most common repair needs on Samsung's WF45 and WF50 series washers. This hub covers the DC34-00028A door lock switch assembly, which fits over 15 Samsung front load washer models from recent years.

Is This the Right Part for Your Model?

Check your washer's model number before ordering. You'll find it on a label inside the door frame or on the back panel of the machine. Common compatible models include the WF45R6300AV, WF45R6100AW, WF45T6000AV, WF50R8500AV, and WF50A8600AV series. This switch assembly replaces several Samsung part numbers including AP6975226, PS12740237, and 4975290.

About This Replacement Part

The door lock switch (also called a door latch assembly) serves a critical safety function — it electronically locks the washer door during the cycle and signals the control board that it's safe to start. When this component fails, your washer typically won't start at all, or it might stop mid-cycle with the door still locked. Some models will display error codes like dE, dE1, or door-related messages on the control panel. The DC34-00028A is Samsung's OEM-grade replacement that includes the complete locking mechanism and wiring harness. Before you begin installation, unplug the washer completely and wear work gloves to protect your hands from sharp edges inside the door frame.

Installation Overview

Replacing the door lock switch requires accessing the front door assembly. You'll need to remove the door boot seal clamp and peel back the rubber boot to reach the latch mounted on the front panel. The process involves disconnecting a wire harness, removing mounting screws, and reversing the steps with your new switch. Always test the repair by running a short cycle to verify the door locks properly and the washer starts without error codes.
