Roper Washer Agitator Not Moving but Drum Spins:... | appliancefaults.com

Technical Background:

The Roper washer uses an electric motor to drive both the agitator and the drum. A series of mechanical linkages and sometimes a directional solenoid, determines whether the motor's power is directed to the agitator for washing or the drum for spinning. The MCU sends 120V AC to the motor and various components based on timer settings and sensor inputs.

Symptoms:

The homeowner observes that the washer drum spins during the spin cycle, but the agitator does not move during the wash cycle. Clothes are not being cleaned effectively.

Possible Causes:

Worn or broken agitator dogs (also known as cogs or pawls).
Stripped agitator coupling.
Failed agitator directional solenoid.
Damaged or broken drive block.
Faulty motor or motor capacitor.
Defective timer or electronic control board (MCU).

Solution:

1

Unplug the washer from the outlet.
2

Remove the agitator cap and any associated hardware (usually a bolt or screw) using a 1/4-inch nut driver.
3

Carefully pull the agitator straight up to remove it. Inspect the agitator dogs (cogs) for wear or breakage. Replace if necessary.
4

Examine the agitator coupling (below the agitator) for signs of stripping or damage. Replace if necessary.
5

If the agitator dogs and coupling are intact, access the motor and directional solenoid (usually located underneath the washer). Use a multimeter to test the solenoid for continuity. A reading of 0 ohms indicates a short; infinity indicates an open. Replace if faulty.
6

Check the drive block (between the motor and transmission) for cracks or breaks. Replace if damaged.
7

If the above components are good, the timer/MCU or motor itself may be at fault. Consider consulting a qualified technician for advanced diagnostics.

Safety Warning:

Always disconnect power (LOTO) to the appliance before performing any repairs. Some components may carry dangerous voltage even when the machine is switched off. Use extreme caution.

Prevention:

Avoid overloading the washer, use the appropriate amount of detergent, and regularly clean the lint filter. Check the agitator dogs every year for wear, replacing when needed.

Expert Tip:

On some Roper models, you can enter a diagnostic mode by pressing a specific sequence of buttons (e.g., Power, Start, Power, Start). This mode may reveal error codes that can pinpoint the problem area. Consult the service manual or online resources for the exact sequence for your model.

Frequently Asked Questions

•How do I access the motor and directional solenoid on my Roper washer?

Typically, you'll need to remove the rear or front panel of the washer cabinet. Consult your washer's service manual or search online for model-specific disassembly instructions. Be sure to disconnect power first.

•What is the proper resistance reading for a functioning directional solenoid?

The resistance reading for a good directional solenoid will vary depending on the model. Generally, it should fall within a range of 100 to 500 ohms. Refer to the service manual or component specifications for the exact value.

•Where can I purchase replacement parts for my Roper washer?

You can purchase replacement parts from appliance parts retailers, both online and in local stores. Be sure to have your washer's model number handy to ensure you order the correct parts.
