GE Dryer Error Code Sn

Sn on a GE dryer is a status indicator that appears during Field Service Mode, the dryer's built-in diagnostic test routine. It means the drive motor switched on and is running correctly during the motor test step. This is a normal, expected display during diagnostics and does not indicate a fault with the dryer.

If Sn is appearing because the dryer is in Field Service Mode, the dryer is in a diagnostic state and normal operation may be interrupted until the mode is exited. Exit the diagnostic mode or perform a power reset before running a normal drying cycle. The code itself does not indicate any unsafe condition.

Because Sn is normally a status indicator rather than a fault, there is often no repair cost involved. If a control board malfunction is causing the code to appear incorrectly, control board replacement on a GE dryer typically ranges from around $150 to $350 depending on the model and labor rates in your area.

In most cases, no repair is needed. Sn is a normal confirmation that the motor is running during a Field Service Mode test. If you did not intentionally enter diagnostics, simply unplug the dryer for about 60 seconds to reset the control board and the code should clear on its own.

Yes, a reset will typically clear Sn from the display. Unplug the dryer from the wall outlet, wait at least 60 seconds, and plug it back in. This exits Field Service Mode and returns the control board to its normal operating state. If the code returns after a reset without you entering diagnostics, the control board may need further inspection.
