Maytag Dryer Error Code UdS

UdS stands for upper dryer door sense error. It means the control board has detected a problem with the signal coming from the upper dryer door switch. When this code is active, the upper dryer cycles and display are disabled. The code must be manually cleared before the upper dryer will operate again.

The upper dryer section is fully disabled when the UdS code is active, so it will not run in that state. If your unit has a lower dryer compartment that is unaffected, it may continue to operate normally. You should not attempt to bypass or ignore the fault, as the door sense circuit is a safety-related system.

The UdS code does not clear automatically. It must be manually cleared through the diagnostic process on the control board. Even after clearing, the code will return if the underlying cause, such as a failed door switch or wiring issue, has not been corrected. Always address the root cause before clearing and returning the unit to service.

Some causes of the UdS code are DIY-friendly. Start by inspecting the upper door switch and all related wiring connections for anything loose, broken, or disconnected. If the door latch is misaligned, adjusting it may resolve the fault. However, replacing the door switch or control board typically requires basic electrical knowledge and comfort working with appliance components.

Repair costs depend on the root cause. A door switch replacement is generally an affordable fix, with parts typically ranging from $15 to $50 and professional labor adding $75 to $150 depending on your area. A control board replacement is more expensive, with parts often ranging from $100 to $300 or more. If the issue is simply a loose wire or power line interference, the repair cost may be minimal.
