Samsung Dryer Error Code 3E — What It Means & How to Fix It

What Does This Error Mean?

The 3E error on a Samsung dryer means the motor's hall sensor has detected a problem. The hall sensor monitors how fast the drum motor is spinning. When the signal is missing or incorrect, the dryer stops to prevent damage. The dryer will not run until the sensor or motor is replaced.

Affected Models

DVE45R6100W
DVG50R5400V
DVE50R8500V
DV42H5000EW
Most Samsung front-load and top-load dryers

Common Causes

The motor hall sensor has failed and is sending no signal to the control board
The wiring harness between the hall sensor and the control board is damaged or loose
The drum motor itself has failed and cannot spin correctly
A foreign object in the drum cavity is preventing the motor from turning freely
The main control board has failed and cannot read the hall sensor signal

How to Fix It

Unplug the dryer from the wall outlet completely before doing anything. Wait 5 minutes to allow residual power to dissipate.

Never work on the dryer while it is connected to power. The motor capacitor can hold a charge.
Check the dryer drum for any foreign objects. Open the door and spin the drum by hand. It should rotate smoothly with light resistance. If it is stiff or won't turn, something may be jammed.

Coins, belt loops, or small garments can get trapped between the drum and the bulkhead and stop the motor.
Try a power reset. With the dryer unplugged for 10 full minutes, plug it back in and run a short cycle. A temporary sensor glitch may clear on its own.

If 3E clears after a reset but returns again, the hall sensor is failing and needs replacement.
If the error persists, the hall sensor inside the motor assembly needs to be tested and most likely replaced. This requires removing the back panel or front panel of the dryer depending on your model.

The hall sensor is a small magnetic sensor attached to the motor. It typically costs $15–$40 as a replacement part.
If replacing the hall sensor does not clear the error, the motor itself has failed and needs full replacement.

A replacement dryer motor typically costs $80–$150 for parts. Have a technician confirm the diagnosis before purchasing a motor.

When to Call a Professional

The 3E error almost always requires replacing the hall sensor or the motor. These are internal parts that require disassembling the dryer cabinet. Contact a Samsung-authorized technician for diagnosis and repair. Expect repair costs of $150–$350 depending on whether the sensor or the full motor needs replacement.

Frequently Asked Questions

What is a hall sensor in a dryer motor?

A hall sensor is a tiny electronic chip that detects a magnetic field. In a dryer motor, it detects the position and speed of the rotating shaft. It sends this information to the control board so the board knows the motor is spinning at the right speed. If the sensor fails, the board sees no rotation signal and triggers error 3E.

Can I reset the 3E error without fixing anything?

You can try a power reset by unplugging the dryer for 10 minutes. If the error clears and stays gone, the issue was a temporary sensor glitch. If 3E comes back after a reset, the hall sensor or motor is physically failing and needs replacement. Do not keep resetting without addressing the root cause.

Is 3E the same as nD on a Samsung dryer?

They are related but different. The nD error means the control board detected no drum rotation. 3E means the motor's internal hall sensor reported a fault. Both indicate a motor-related problem, but the exact diagnosis differs. A technician can use a service mode diagnostic to determine which component has failed.
