Empower your inner electrician: how to test ge dryer motors like a pro

Is your GE dryer acting up, leaving you with damp clothes and frustration? One potential culprit could be a faulty motor. Testing the motor is crucial to diagnose the issue and determine if it needs to be replaced. This comprehensive guide will walk you through the process of testing a GE dryer motor, empowering you to troubleshoot and resolve the problem like a pro.

Safety First

Before starting any electrical work, always remember to:

• Unplug the dryer from the power outlet.
• Allow the dryer to cool down completely.
• Wear gloves and safety glasses for protection.

Materials You’ll Need

• Multimeter
• Screwdriver (Phillips and flathead)
• Electrical tape
• Replacement motor (if necessary)

Step-by-Step Testing Procedure

1. Access the Motor

• Remove the back panel of the dryer by unscrewing the screws holding it in place.
• Locate the motor, typically positioned at the bottom of the dryer.

2. Disconnect the Wires

• Carefully disconnect the wires connected to the motor using a screwdriver.
• Mark each wire with tape to ensure proper reconnection later on.

3. Continuity Test

• Set your multimeter to the “Continuity” setting.
• Connect one probe to one of the motor terminals and the other probe to the opposite terminal.
• If the multimeter beeps, the motor winding is continuous. If it doesn’t beep, the winding is open and the motor is faulty.

4. Insulation Test

• Set the multimeter to the “Resistance” setting.
• Connect one probe to a motor terminal and the other probe to the metal frame of the dryer.
• If the multimeter reads infinity, the motor insulation is intact. If it reads a low resistance value, the insulation is damaged and the motor is faulty.

5. Ohm Test

• Set the multimeter to the “Ohms” setting.
• Connect one probe to each motor terminal.
• The multimeter should read a specific resistance value, which varies depending on the motor model. Refer to the dryer’s manual for the correct value. If the resistance is significantly different, the motor is faulty.

6. Inspect the Rotor

• Remove the rotor from the motor shaft by unscrewing the retaining screw.
• Inspect the rotor for any signs of wear, damage, or debris.
• If the rotor is damaged, it may need to be replaced.

7. Reassemble and Test

• Reassemble the motor by reconnecting the wires and installing the rotor.
• Plug the dryer back in and power it on.
• If the motor is functioning properly, the dryer will start spinning the drum.

Troubleshooting Tips

• No continuity: Open winding in the motor. Replace the motor.
• Low insulation resistance: Damaged insulation. Replace the motor.
• Incorrect ohm reading: Faulty motor winding. Replace the motor.
• Damaged rotor: Wear or damage to the rotor. Replace the rotor or motor.

Conclusion

Testing a GE dryer motor is a relatively straightforward process that can help you pinpoint the root cause of your dryer problems. By following the steps outlined in this guide, you can accurately diagnose the motor’s condition and determine whether it needs to be replaced. Remember, always prioritize safety and refer to the dryer’s manual for specific instructions and troubleshooting tips.
