Roper Washer Drum Not Turning: Troubleshooting Guide -... | appliancefaults.com

Technical Background:

The Roper washer uses a motor control unit (MCU) to regulate the motor's operation. The MCU sends voltage to the motor windings and relies on feedback from sensors, like the lid switch, to control the wash cycle. A start capacitor assists the motor in starting and overcoming inertia. When voltage isn't correctly supplied to the motor or the motor encounters excessive resistance, the motor may only hum without turning.

Symptoms:

The Roper washing machine is making a humming sound, but the drum is not rotating during the wash cycle. The clothes remain stationary, and the wash cycle does not progress as expected.

Possible Causes:

Failed motor start capacitor
Worn or broken drive belt
Defective motor
Obstruction in the drum (e.g., clothing caught between drum and tub)
Faulty lid switch
Control board malfunction

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Disconnect the water supply hoses.
3

Remove the washer's cabinet. Refer to the service manual for specific instructions. Usually involves removing screws at the rear or under the front panel using a 1/4-inch nut driver.
4

Inspect the drive belt for wear or breakage. Replace if necessary.
5

Check the motor start capacitor. If it's bulging or leaking, replace it. You can test it with a multimeter for capacitance (microfarads).
6

Manually try turning the drum. If it's difficult to turn, check for obstructions. Remove any obstructions.
7

Test the lid switch for continuity with a multimeter when the lid is closed. Replace if faulty.

Safety Warning:

Disconnect power to the washer before any troubleshooting. Lock Out/Tag Out (LOTO) procedures must be followed to prevent accidental power-up. High voltage is present when the washer is plugged in.

Prevention:

Avoid overloading the washer. Regularly inspect the drive belt for wear. Clean the lint filter after each load to prevent excessive buildup and strain on the motor. Level the washer to prevent vibrations and premature wear.

Expert Tip:

Some Roper washers have a diagnostic mode. Consult the service manual for the specific sequence for your model. This can help pinpoint the fault code if the control board is the issue.

Frequently Asked Questions

•How do I access the diagnostic mode on my Roper washer?

The diagnostic mode sequence varies by model. Usually, it involves pressing a combination of buttons (e.g., start, cancel, power) in a specific order within a short timeframe. Refer to the service manual for your specific model.

•Where can I find a replacement motor start capacitor?

Replacement motor start capacitors can be found at appliance parts retailers, both online and in physical stores. Be sure to match the microfarad (uF) and voltage ratings of the original capacitor.

•How do I determine if the motor itself is bad?

If you've ruled out the start capacitor and drive belt, and the drum still doesn't turn, the motor could be the issue. Testing the motor windings for continuity and resistance with a multimeter can help confirm this. Consult the service manual for the correct resistance values. If any winding is open or shorted, the motor needs replacement. Also visually inspect the motor windings for burning.
