Whirlpool Dryer Error Code UF

The UF code indicates an upper dryer motor sense circuit error detected by the control board. It can be triggered by actual circuit or component faults, or by interference from power line fluctuations. When this code is active, the upper dryer unit is disabled and its display will not function. The code must be manually cleared before the upper dryer can operate again.

Start by manually clearing the diagnostic code, which is the recommended first step. If the code does not return, a transient power disturbance was likely the cause. If it comes back, inspect the motor sense circuit wiring and connectors for damage, and evaluate whether the control board or upper dryer motor requires replacement.

If the code was caused by a power line event and clears without returning, there is no repair cost. If the control board needs replacement, parts and labor typically range from $150 to $400 depending on the specific model and service rates in your area. A motor replacement, if required, can bring costs to a similar or higher range.

The UF code requires a manual diagnostic clear rather than a simple power reset. After clearing the code, monitor whether it returns during normal operation. If the code reappears, a persistent hardware fault in the motor sense circuit or control board is likely and further diagnosis is needed.

The upper dryer unit is automatically disabled when the UF code is active, so it will not run while the code is present. If your unit has a lower dryer section, that portion may still be operational. Do not attempt to bypass the error and force the upper dryer to run before diagnosing and resolving the fault.
