Admiral Washer Recalibration Guide: After Drive Belt... | appliancefaults.com

Technical Background:

The MCU (Main Control Unit) controls the motor speed and direction based on feedback from a speed sensor. When a drive belt is replaced, the MCU may need to be recalibrated to account for slight variations in belt tension or pulley alignment. Voltage paths to the motor and speed sensor are critical for proper operation.

Symptoms:

The washer may exhibit symptoms such as improper spin speed, error codes related to motor speed or belt slippage, or failure to advance through the wash cycle after a drive belt replacement.

Possible Causes:

Incorrect drive belt system.
MCU (Main Control Unit) lost its initial settings.
Misalignment of the motor or pulleys.
Damaged or faulty speed sensor.
Voltage fluctuations during the replacement process.
Mechanical obstruction of the drum's rotation.

Solution:

1

Disconnect the washer from the power outlet (120V AC). Use a multimeter to confirm there is no voltage at the outlet before proceeding.
2

Access the service mode. Press and hold the Start/Pause button for 3 seconds, then simultaneously press the Power button. (Note: Specific sequence may vary slightly depending on the exact Admiral model. Consult the service manual).
3

Navigate to the recalibration or auto-test option using the cycle selector knob. Consult the service manual if needed. A 1/4-inch nut driver may be needed to remove the control panel for better access.
4

Select the recalibration cycle and press Start/Pause to initiate. The washer will automatically run through a series of drum rotations and speed adjustments.
5

Monitor the washer during the recalibration process. Ensure there are no unusual noises or vibrations. Check for proper belt tracking on the pulleys.
6

Once the recalibration cycle is complete, the display should indicate successful completion. Note any error codes if the recalibration fails.
7

Unplug the washer for 5 minutes, then plug it back in to allow the MCU to fully reset. Run a test load to verify proper operation.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energization. Washing machines use 120V AC and can cause electric shock. If you are not comfortable working with electricity, consult a qualified appliance technician.

Prevention:

Regularly inspect the drive belt for wear and tear. Avoid overloading the washer, as this can put excessive strain on the belt and motor. Clean the area around the motor and pulleys to prevent debris buildup.

Expert Tip:

If the recalibration fails repeatedly, suspect a faulty speed sensor or a damaged motor. Use a multimeter to check the speed sensor's resistance, typically around 1000-2000 ohms. Service mode often allows manual motor testing for further diagnosis.

Frequently Asked Questions

•What if the washer doesn't enter service mode?

Double-check the button sequence for your specific model. Some Admiral washers have slightly different entry procedures. Consult the service manual or search online for your model's specific sequence.

•How do I check the speed sensor?

Locate the speed sensor, typically near the motor. Disconnect the wires and use a multimeter to measure the resistance. A typical reading is between 1000 and 2000 ohms, but consult the service manual for the exact specification. An open or shorted sensor indicates a fault.

•What if the washer still shows an error code after recalibration?

Note the specific error code. This will help narrow down the problem. It could indicate a problem with the motor, speed sensor, wiring harness, or the MCU itself. Consult the service manual for the error code definition and troubleshooting steps. A 5/16-inch socket might be required to remove panels for access.
