Whirlpool Dryer Error Code UC

The UC code on a Whirlpool dryer indicates an upper dryer motor control circuit error. This fault disables the upper dryer cycles and turns off the upper dryer display until the code is manually cleared. It is most commonly seen on dual or stacked dryer configurations where the upper unit has its own dedicated motor control system.

The UC code must be cleared manually through the dryer's diagnostic mode rather than through a simple power reset. Once cleared, run a test cycle to confirm the code does not return. If the code reappears, there is an active fault in the motor control circuit that requires further diagnosis.

Repair costs depend on the root cause. If the issue is a loose or corroded wiring connection, the cost may be limited to a service call fee, typically in the range of $75 to $150. If the motor control board needs replacement, parts and labor combined can range from $200 to $400 or more depending on your location and the specific board required. A motor replacement would generally fall in a similar or higher range.

Start by manually clearing the diagnostic code through the dryer's service or diagnostic mode. If the code does not return, the fault may have been a one-time glitch. If the UC code comes back after clearing, inspect the wiring harness connections to the upper motor and evaluate the motor control board for damage or failure, as replacement of those components may be required.

When the UC code is active, the upper dryer disables itself automatically, so you cannot operate the upper unit in that state. The lower unit may remain functional depending on your dryer model. It is best to resolve the fault before returning the upper dryer to regular use, as the code indicates a motor control circuit problem that could worsen if ignored.
