Quick And Easy: How To Test A Whirlpool Dryer Motor For Maximum Efficiency

Is your Whirlpool dryer giving you grief by refusing to tumble your clothes? Before calling in a repair technician, consider testing the dryer motor yourself. This comprehensive guide will walk you through the steps on how to test a Whirlpool dryer motor, empowering you to diagnose and potentially resolve the issue without breaking the bank.

Safety Precautions

Before you start, ensure your safety by:

• Unplugging the dryer from the power outlet.
• Allowing the dryer to cool down completely.
• Wearing protective gloves and safety glasses.

Tools You’ll Need

• Multimeter
• Screwdriver set
• Continuity tester (optional)

Step 1: Inspect the Motor

• Locate the motor, typically situated at the back or bottom of the dryer.
• Visually inspect the motor for any signs of damage, such as burnt wires or loose connections.

Step 2: Check the Power Supply

• Use a multimeter to test the voltage at the motor’s terminals.
• Ensure the voltage matches the specifications indicated on the motor’s label.
• If the voltage is insufficient, check the power cord, circuit breaker, and fuse.

Step 3: Test Motor Continuity

• Disconnect the wires from the motor terminals.
• Set your multimeter to the continuity setting.
• Touch one probe to each terminal and check if the meter beeps, indicating continuity.
• If the meter does not beep, the motor may have an open circuit and needs to be replaced.

Step 4: Check Motor Resistance

• Set your multimeter to the resistance setting.
• Touch one probe to each terminal and measure the resistance.
• Compare the measured resistance to the specifications provided by Whirlpool.
• If the resistance is significantly different, the motor may have a problem and should be replaced.

Step 5: Test Motor Run Capacitor (Optional)

• If your dryer has a run capacitor, disconnect it from the motor.
• Use a capacitance meter to test the capacitor’s capacitance.
• Compare the measured capacitance to the specifications on the capacitor.
• If the capacitance is significantly lower or higher than the specifications, the capacitor may be faulty and needs to be replaced.

Step 6: Test Motor Start Capacitor (Optional)

• If your dryer has a start capacitor, disconnect it from the motor.
• Charge the capacitor by briefly connecting it to a power source.
• Discharge the capacitor by touching its terminals with a screwdriver.
• If the capacitor does not discharge properly, it may be faulty and needs to be replaced.

Troubleshooting Common Motor Issues

• Motor not running: Check the power supply, motor continuity, and capacitors.
• Motor running slowly: Check the motor resistance and voltage.
• Motor making noise: Inspect the motor for loose parts or bearings.
• Motor overheating: Check the motor for excessive friction or a faulty capacitor.

Next Steps

If your tests indicate a faulty motor, you can either replace it yourself or call in a qualified repair technician. Replacing a dryer motor is a moderately complex task that requires some electrical knowledge and mechanical skills.

Wrapping Up

Testing a Whirlpool dryer motor is a straightforward process that can help you identify and resolve common motor issues. By following these steps and troubleshooting tips, you can diagnose the problem and get your dryer back up and running in no time. Remember to always prioritize safety and seek professional assistance if you are not comfortable or confident in performing these tests.
