If the washer agitates and drains but won't spin, the built-in diagnostic mode can help narrow the fault. This guide shows how to enter diagnostics on a Samsung WA40J3000WA and how to inspect the wiring, capacitor, shift actuator, and TMR sensor that commonly stop the washer from reaching spin speed.

ШагиSteps

Confirm diagnostic mode applies to your control panel

Use this diagnostic procedure only for the similar Samsung washers with the shown control panel type.
If the control panel is a different color or layout, the button combination may be different.

Enter diagnostic mode

Plug the washer in.
Press the Power button to turn the washer on.
Press and hold the Temp button until diagnostic mode starts.
The source procedure indicates it may take about 8 seconds on this model.

Read and scroll stored error codes

Identify the error code by watching which indicator lights blink.
Treat steady-on lights as non-code indicators unless they are also blinking.
Turn the cycle dial to scroll through stored failures and faults.
Write down the exact blinking-light pattern before doing repairs.

Know the limits of the code information provided

Plan for more than one possible fix, because a single problem can produce multiple codes or light patterns.
WARNING: The source material does not include the full chart of all error-code light patterns and meanings for this model.
Use the blinking-light pattern you recorded to look up the code in the model’s tech manual if it isn’t covered by the checks below.

Prepare for no-spin troubleshooting under the washer

Unplug the washer before inspecting parts under the cabinet.
Access the underside of the washer to reach the motor and transmission area.
Focus on the shift actuator, the capacitor, and the TMR sensor when the washer refuses to spin.
Check wiring carefully, because vibration can unhook or sever wires on this washer style.

Inspect the capacitor and its wiring

Locate the capacitor and find the blue wire and the red wire connected to it.
Gently tug the wires to confirm they aren’t loose, disconnected, or severed.
Inspect the capacitor housing for damage or bulging material coming out of the casing.
Replace the capacitor if the casing looks damaged or swollen.

Test the shift actuator and check its wiring

Locate the shift actuator, which shifts the washer from agitate to spin.
Disconnect the Molex connector from the shift actuator.
Use a multimeter to measure the shift actuator resistance at the connector.
Confirm the reading is between 1000 and 1100 Ω.
Inspect and gently tug the small shifter wire located just above the shift actuator for damage.

Access the TMR sensor

Locate the TMR sensor on the top side of the motor area.
Remove the large bracket to reach the TMR sensor.
Remove additional motor and transmission components as needed to get clear access to the sensor.
WARNING: The source material does not specify the exact removal order or screw sizes for the bracket and related components.

Inspect the TMR sensor and harness

Identify the TMR sensor and the wire harness connected to it.
Understand that the TMR sensor calculates the motor’s run speed.
Inspect the harness and sensor terminals for a snapped or disconnected wire.

Repair the TMR sensor wiring or replace the assembly

Remove the plastic cover piece by removing the two screws that hold it in place.
Repair a snapped wire by soldering the wire back onto the TMR sensor terminal.
Disconnect the Molex harness if needed to make the soldering repair easier.
Use tweezers to help with the Molex connector pins if you don't have a dedicated extractor.
Replace the entire shifting assembly if you can’t solder, because Samsung doesn’t sell the TMR sensor by itself.
Use the slack in the harness to position the wire for repair if extra length is available.

Reassemble and confirm the spin function

Reinstall the plastic cover, the bracket, and any motor or transmission components you removed.
Reconnect all harnesses and confirm each connector is fully seated.
Plug the washer in and run a test to confirm it spins normally.

Reassemble the washer and confirm it completes a full spin before returning it to service. Repair didn't go as planned? Ask our Answers community for help.
