If you're not comfortable with this type of testing, it's best to consult a qualified appliance repair technician. Replacing the control board is a relatively straightforward process, but it's important to use the correct replacement part for your specific dryer model. You can usually find the part number on the control board itself or in the dryer's user manual. When installing the new control board, be sure to follow the manufacturer's instructions carefully. Pay close attention to the wiring connections and make sure everything is properly seated and secured.

Before you jump to the conclusion that the control board is faulty, it's a good idea to rule out other potential causes, such as loose wiring or a faulty motor control unit. Sometimes, a seemingly unrelated issue can cause the control board to display an error code. If you've checked all the other possible causes and the E RO error persists, then it's likely that the control board is the culprit. Keep in mind that replacing the control board can be a bit expensive, so it's worth considering whether it's more cost-effective to repair the dryer or replace it altogether. If your dryer is relatively old and has other issues, it might make more sense to invest in a new appliance. However, if your dryer is relatively new and in good condition, replacing the control board can be a worthwhile investment.

3. Defective Motor Control Unit

A defective motor control unit is another potential cause of the E RO error in your Speed Queen dryer. The motor control unit is responsible for regulating the speed and direction of the dryer's motor. If it's not functioning correctly, it can disrupt the communication with the control board, leading to the E RO error. Just like with the control board, diagnosing a faulty motor control unit can be a bit challenging and may require some technical expertise. One way to check the motor control unit is to visually inspect it for any signs of damage, such as burnt components or corrosion. If you notice any of these issues, it's a good indication that the motor control unit is faulty and needs to be replaced.
