Roper Washer Agitates But Won't Spin: Troubleshooting... | appliancefaults.com

Technical Background:

The Washer's Main Control Unit (MCU) sends a 120V AC signal to the motor and drain pump relays to initiate the spin cycle. The lid switch must be closed for the MCU to enable the spin cycle. Voltage travels from the breaker panel through the power cord to the control board, and then to the motor and drain pump. Failures in any of these components will prevent the spin cycle from starting.

Symptoms:

The Roper washer fills and agitates normally during the wash cycle. However, when the cycle advances to the spin portion, the drum does not spin, leaving the towels soaking wet.

Possible Causes:

Lid switch malfunction.
Faulty motor coupling.
Worn or broken drive belt.
Defective motor or motor windings.
Malfunctioning drain pump.
Clogged drain hose.

Solution:

1

Disconnect power to the washer at the breaker panel (LOTO).
2

Inspect the lid switch for continuity using a multimeter. A closed lid should show continuity; an open lid should not. Replace if faulty.
3

Check the motor coupling for wear or breakage. This is a common failure point. Replace if damaged.
4

Examine the drive belt for cracks or looseness. Replace or adjust as needed. A loose belt can cause spin failure.
5

Test the motor windings for continuity using a multimeter. Look for open windings or shorts to ground. Replace motor if needed.
6

Verify the drain pump is operating and not clogged. Remove the pump and check for obstructions. Clean or replace if necessary. A full tub can prevent spinning.
7

Inspect the drain hose for clogs or kinks. Disconnect the hose and flush it out.

Safety Warning:

Disconnect power to the washer at the breaker panel before performing any repairs (LOTO - Lock Out, Tag Out). High voltage is present inside the appliance. Wear appropriate safety gear.

Prevention:

Regularly check and clean the lint filter to prevent clogs. Avoid overloading the washer. Inspect the drive belt and motor coupling annually for wear.

Expert Tip:

Many Roper washers have a diagnostic mode. Simultaneously press and hold the Start/Pause and Water Level buttons for 3 seconds to enter diagnostic mode. Error codes will be displayed, which can help pinpoint the problem. Consult the service manual for code definitions.

Follow-up Questions:
• What resistance should I expect to see on the motor windings?

The resistance varies depending on the motor. Generally, winding resistance is low, a few ohms. Refer to the service manual for specific values.

• How do I access the motor coupling?

You typically access the motor coupling by removing the washer's cabinet. This may involve removing screws at the back or sides of the machine.

• What is the proper tension for the drive belt?

The drive belt should have some play but should not be excessively loose. A good rule of thumb is about 1/2 inch of deflection when pressed in the middle of its longest span.
