Roper Top Load Washer Not Spinning: Troubleshooting and... | appliancefaults.com

Technical Background:

The MCU (Main Control Unit) controls the spin cycle by sending voltage to the motor. This voltage passes through safety interlocks (like the lid switch) and various components such as the motor capacitor and motor windings. If any component in this path fails, the spin cycle will not initiate. The MCU also monitors sensor inputs to determine if the drum is draining before initiating spin.

Symptoms:

The Roper top load washer fills with water and agitates normally, but it fails to spin during the spin cycle, leaving clothes soaked.

Possible Causes:

Lid switch malfunction
Drive belt issues (worn or broken)
Motor coupling failure
Drain pump obstruction
Faulty motor or capacitor
Defective electronic control board (MCU)

Solution:

1

Unplug the washer from the outlet. Always lockout/tagout the breaker.
2

Check the lid switch for continuity with a multimeter. Should read continuity when the lid is closed.
3

Inspect the drive belt for wear or breakage. Replace if damaged.
4

Examine the motor coupling for damage. It connects the motor to the transmission. Replace if broken.
5

Verify the drain pump is clear of obstructions. Remove any debris.
6

Test the motor capacitor (if equipped). A multimeter with capacitance testing function is required. Replace if out of spec.
7

Check voltage to the motor during the spin cycle using a multimeter. Should read approximately 120V AC.

Safety Warning:

Disconnect power to the appliance at the breaker panel before performing any repairs. Capacitors can store a dangerous electrical charge even when the appliance is unplugged. Lockout/Tagout (LOTO) procedures are critical to electrical safety. High voltage is present in many parts of the washer.

Prevention:

Regularly check and clean the drain pump filter. Avoid overloading the washer. Inspect the drive belt periodically for wear. Wipe down the interior of the washer after each use to prevent mildew buildup.

Expert Tip:

Some Roper washers have a diagnostic mode. To enter it, rapidly rotate the cycle selector knob clockwise three clicks, then counter-clockwise two clicks, then clockwise one click. This may display error codes that pinpoint the problem. Use caution when running diagnostic tests.

Frequently Asked Questions

•How do I access the lid switch on my Roper top load washer?

Typically, you'll need to remove the top panel of the washer. This often involves removing screws at the rear of the unit. Once the top is lifted, the lid switch will be visible and accessible.

•What is the correct belt tension for the drive belt?

The belt should have some give, but not be excessively loose. A good rule of thumb is about 1/2 inch of deflection when you press on the belt midway between the pulleys.

•Where can I find a wiring diagram for my specific Roper washer model?

Wiring diagrams are often located inside the control panel or on the back of the washer. You can also find them online through appliance parts suppliers by searching with your model number.
