Admiral Washer: Shifting Actuator vs. Motor Capacitor -... | appliancefaults.com

Technical Background:

The MCU (Main Control Unit) controls the shifting actuator and the motor. The MCU sends signals to the shifting actuator to engage the appropriate gear for washing, rinsing, and spinning. The motor capacitor provides the initial boost to the motor for starting. Voltage paths from the MCU to the actuator and motor are critical for proper operation. A failure in either the actuator, capacitor, or the MCU's control circuit will cause the washer to malfunction.

Symptoms:

The homeowner observes the washer not shifting between cycles (e.g., wash to spin). The washer may be making unusual noises or simply stops mid-cycle. The error code display (if applicable) might indicate a motor or shifting problem. Agitation may be weak or nonexistent, or the spin cycle fails to engage properly.

Possible Causes:

Faulty shifting actuator
Defective motor capacitor
Wiring harness damage
Corroded connections at the motor or control board
Main control board (MCU) failure
Overloaded washer drum

Solution:

1

Disconnect power to the washer at the breaker panel. Verify no voltage is present at the wall outlet using a multimeter.
2

Access the washer's control panel and locate the motor capacitor. Visually inspect the capacitor for bulging or leaking.
3

Discharge the capacitor using a 20,000-ohm, 5-watt resistor before handling.
4

Using a multimeter, test the capacitance of the motor capacitor. Compare the reading to the value printed on the capacitor's label. Replace the capacitor if the reading is significantly different.
5

Locate the shifting actuator. Inspect wiring connections for damage or corrosion.
6

Use a multimeter to test the voltage at the shifting actuator connector during the shift cycle. Check for approximately 120V AC. If voltage is present, but the actuator doesn't function, replace the actuator.
7

If no voltage is present at the actuator, suspect a faulty main control board (MCU) or a wiring problem. Check the wiring harness for continuity using a multimeter.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Lock Out/Tag Out (LOTO) procedures must be followed. Capacitors can store a dangerous electrical charge even after the power is disconnected. Discharge the capacitor before handling. High voltage is present when the machine is powered on.

Prevention:

• Avoid overloading the washer drum.
• Use the correct type and amount of detergent.
• Periodically inspect hoses for leaks or damage.
• Clean the drain pump filter regularly.

Expert Tip:

Many Admiral washers have a diagnostic mode. Access the diagnostic mode by pressing a specific sequence of buttons (refer to the service manual for the exact sequence). The diagnostic mode can display error codes and allow you to test individual components.

Frequently Asked Questions

•How do I safely discharge a capacitor?

Use a 20,000-ohm, 5-watt resistor with insulated leads. Connect the resistor leads to the capacitor terminals for several seconds to slowly discharge the stored energy.

•What are the typical capacitance values for washer motor capacitors?

Capacitance values vary by motor size, but typical values range from 10 to 20 microfarads. Consult the motor capacitor's label for the correct value for your specific model.

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

The diagnostic mode access sequence varies by model. Consult the service manual or search online for the specific button combination for your washer model. A common sequence involves pressing a combination of buttons like 'Start,' 'Cancel,' and 'Power' in a specific order.
