Speed Queen Dryer Error Code FAN COMM ERROR

The FAN COMM ERROR means the output control board tried to communicate with the fan motor three times and received no response on any attempt. Because the fan is critical for airflow and safe dryer operation, the machine locks out and will not run until the error is cleared and the underlying fault is corrected. The cause is typically a wiring fault, a failed fan motor, or in some cases a faulty output board.

No, you should not attempt to bypass or override this error to run the dryer. The fan motor is responsible for moving heated air through the drum and exhausting it safely. If the fan is not operating correctly, heat can build up inside the dryer and create a fire hazard. The machine correctly refuses to operate until the fault is resolved.

A knowledgeable DIYer can start by clearing the error and checking whether it returns, then visually inspecting the wiring harness and connectors between the fan motor and the output board for obvious damage or loose connections. However, testing the fan motor's communication circuit and diagnosing the output board typically requires electrical testing tools and familiarity with the specific wiring layout of the machine. If the visual inspection does not reveal a clear problem, a qualified appliance technician is the recommended next step.

You can clear the fatal error by fully powering down the machine, using the Clear Fatal Error key combination on the control panel, or sending a Clear Fatal Error command through a connected laundry network system. However, if the underlying fault is still present, the error will return as soon as the dryer attempts to operate again. A reset alone only clears the latched code and does not fix the root cause.

Repair costs depend heavily on which component has failed. If only a wiring connector needs to be reseated or replaced, costs would typically fall in the range of $50 to $150 for a service call. Fan motor replacement generally costs $150 to $350 including parts and labor. Output board replacement tends to be the most expensive repair, often ranging from $200 to $450 depending on the model and labor rates in your area.
