When your Samsung dryer keeps spinning even after the cycle ends or the power is turned off, it’s not just a glitch — it’s a sign of a deeper electrical issue inside the control board. This unusual but common failure means the drum motor continues to run as soon as the door is shut, even if the display is off. At HomeFix Appliance Repair, we frequently encounter this problem across Houston, Katy, Sugar Land, and Memorial. In this article, we’ll explain why it happens, how to check it yourself, and what it takes to fix it safely and permanently.
Why Is My Samsung Dryer Drum Still Spinning After the Cycle Ends?
If your Samsung dryer continues spinning with no active cycle, the likely cause is a stuck motor relay on the main control board. This means that even though you pressed “Power Off,” the drum keeps moving because the internal circuit is still delivering power to the motor.
Key Symptoms:
- Drum spins as soon as you close the door—even with the control panel off.
- Control buttons do nothing.
- The only way to stop it is to open the door or unplug the machine.
Real Case: Samsung DV45K6500EV/A3 Repair in Memorial (77042)
A customer from Memorial, Houston (ZIP 77042), contacted us with this exact issue on their Samsung dryer DV45K6500EV/A3. The drum would run continuously with the door closed, and only stop when the door was opened.
We diagnosed the issue as a stuck power relay on the control board (PBA). It’s a known failure mode with Samsung and LG dryers, caused by:
Relay contact fatigue
Voltage spikes
Overheating
Manual door openings mid-cycle
We replaced the entire main board (part DC92-01896A), and the dryer resumed normal function.
How to Test Your Samsung Dryer If It Won’t Stop Spinning
If you’re comfortable with simple tests, Samsung dryers like the DV45K6500EV/A3 offer built-in diagnostic modes. Here’s how to check it:
Use Smart Install Mode to Test Motor:
Turn on the dryer.
Press and hold “Adjust Time Up” + “Temp” for 7 seconds.
Display shows:
SC(Smart Check).Open and close the door — drum behavior should respond to commands.
Press Start to test motor and heater.
If the motor starts turning without input or won’t stop, that confirms the relay is likely stuck.
Why Does This Happen in Samsung and LG Dryers?
Both Samsung and LG use control boards with Chinese-manufactured relays. These relays control high voltage to the motor. Over time, due to:
Wear and tear
Surge from mid-cycle door openings
Moisture or overheating
…the relay contacts can fuse together. Once this happens, the dryer loses the ability to control motor power via software.
And no—pressing “Power Off” won’t help.
What’s the Fix?
Unfortunately, the relay cannot be replaced separately on most Samsung boards because the board is filled with a gel compound (epoxy). This makes component-level repair nearly impossible.
Best Solution:
Replace the entire main control board.
At HomeFix Appliance Repair, we carry and install:
Samsung PBA boards
LG main boards
Whirlpool, GE, Frigidaire control modules
We replace, calibrate, and test everything the same day (if parts are in stock).
What’s the Fix?
Always press Pause or Stop before opening the door mid-cycle.
Opening the door while the motor is running causes arcing and relay stress.Keep your dryer vent clean.
A clogged vent causes overheating, which shortens the life of internal components.Avoid overloading the dryer.
Heavy loads demand higher motor torque, increasing relay wear.Use a surge protector.
Especially important in Houston where power surges are common.
Do LG Dryers Have the Same Problem?
Yes. We’ve seen stuck relay issues in many LG models—especially older ones made between 2014 and 2021. The root cause is the same: overworked or heat-stressed relays on the control board.
How Much Does It Cost to Fix a Dryer That Won’t Stop Spinning?
In the Houston area, expect:

Can You Fix It Yourself?
Yes, but only partially.
Unplug the dryer. This cuts all power and ensures safety.
Close the door and listen. If the drum still tries to move or hums before unplugging — that’s a sign of a stuck relay.
Try turning the dryer on, then off from the control panel. If the drum continues to spin, it confirms the control panel is not in control — the motor is stuck “ON” via the board.
Open the door. If the drum stops immediately, your door switch is fine, and the issue is likely the motor relay on the control board.
🛠️ If the drum only stops when you open the door or unplug the dryer, your control board must be replaced. The relay is stuck and cannot be repaired individually.
