Whirlpool Dryer Error Code F:46

F:46 means the motor control board has detected an over-current or over-torque condition in the blower motor circuit. The blower motor moves air through the drum and exhaust system, and when it draws too much current or encounters too much mechanical resistance, the control board stops operation and displays this code. Common triggers include blocked venting, a clogged lint system, or a worn blower motor.

You should not continue running the dryer while this code is active. The fault indicates the blower motor is under stress, and running the dryer with reduced or blocked airflow can cause overheating inside the drum and exhaust system. Operating the dryer in this condition risks damaging internal components or creating a fire hazard, particularly if lint buildup is involved.

A power reset by unplugging the dryer for a few minutes may temporarily clear the display, but the code will return if the underlying problem has not been resolved. The motor control board will detect the over-current or over-torque condition again as soon as the blower motor is put under the same stress. A lasting fix requires identifying and correcting the root cause before the fault code will stay cleared.

Some causes of F:46 are DIY-friendly. Cleaning the lint filter, clearing the exhaust duct, and inspecting the blower housing for lint buildup are tasks most homeowners can handle. If those steps do not clear the fault, diagnosing the blower motor or motor control board requires basic electrical testing skills and access to the service diagnostic procedure TEST #3b, which is better suited for an experienced DIYer or a professional technician.

Repair costs vary depending on the root cause. Clearing a blocked vent or lint system costs little to nothing beyond your time. Replacing a failed blower motor typically runs in the range of $100 to $250 for parts and labor. A motor control board replacement is generally more expensive, often ranging from $150 to $350 or more depending on parts availability and labor rates in your area.
