Whirlpool Dryer Error Code F-46

F-46 means the motor control board has detected an over-current or over-torque condition on the blower motor. The blower motor is the component that circulates air through the drum and exhausts it outside. The dryer shuts down to prevent motor or control board damage. The fault is most often related to airflow restrictions, a blocked blower wheel, or a worn motor.

No, you should not continue running the dryer while F-46 is active. An over-current condition on the blower motor indicates the motor is under excessive stress, and continued operation can damage the motor, the control board, or in a worst-case scenario, create a fire hazard if airflow is severely restricted. Resolve the underlying cause before resuming normal use.

Repair costs vary depending on the root cause. Cleaning a clogged vent or blower wheel costs little to nothing if done yourself. A replacement blower motor typically runs in the range of $50 to $150 for the part, while a motor control board can range from $100 to $250 or more depending on the model. Adding professional labor will increase the total cost by $75 to $200 or more depending on your location and the complexity of the repair.

Some causes of F-46 are DIY-friendly, particularly clearing lint from the exhaust vent, cleaning the blower wheel, or thoroughly cleaning the lint filter. If those steps do not resolve the fault, further diagnosis using TEST #3b is required to determine whether the blower motor or motor control board has failed. Replacing those components involves working with electrical parts and is best handled by a technician if you are not comfortable with appliance repair.

A power reset may temporarily clear the F-46 code, but the fault will return if the underlying cause is not corrected. If the blower motor is being overloaded by a restriction or is failing internally, the motor control will detect the problem again as soon as the dryer runs. Always diagnose and fix the root cause rather than relying on resets.
