Maytag Washer Error Code 130: Rotor Position Sensor... | appliancefaults.com

Technical Background:

error code 130 indicates a fault with the rotor position sensor, which provides feedback to the motor control unit (MCU) about the motor's position. The MCU uses this information to control the motor's speed and direction. The rotor position sensor usually sends a variable voltage signal back to the MCU. If the MCU detects an out-of-range signal or no signal, it will throw an error code. The voltage path travels from the MCU, through the harness, to the sensor, and returns back to the MCU. Any interruption in this path causes the error.

Symptoms:

The washer displays error code 130, and the motor may not start or may run erratically. The wash cycle may be interrupted. The machine may vibrate excessively or make unusual noises.

Possible Causes:

Faulty rotor position sensor.
Wiring harness issue between the motor and the MCU.
Loose connection at the motor control unit (MCU).
Damaged motor control unit (MCU).
Foreign object obstructing rotor movement.

Solution:

1

Disconnect power to the washer by unplugging it from the outlet.
2

Locate the rotor position sensor, typically near the motor. Use a 1/4-inch nut driver to remove any access panels.
3

Inspect the wiring harness connecting the sensor to the MCU for any damage or loose connections. Check for continuity with a multimeter.
4

Use a multimeter to check the sensor's resistance. Refer to the service manual for the correct ohm reading. Typically, it will be between 500-1500 ohms, but consult the service manual for the specific model.
5

If the sensor's resistance is outside the specified range, replace the rotor position sensor. Part number can be found on the sensor.
6

If the wiring and sensor are good, inspect the MCU for damage. Replace the MCU if necessary. Test voltage in and voltage out of the MCU. Typically 5V DC.
7

Reconnect power and run a test cycle to verify the repair.

Safety Warning:

Always disconnect power to the washer before performing any repairs. Lockout/Tagout (LOTO) procedures should be followed to prevent accidental power-up. High voltage is present within the appliance. Do not touch any internal components with wet hands.

Prevention:

Periodically inspect the wiring harness for any signs of wear or damage. Ensure the washer is level to prevent excessive vibration. Avoid overloading the washer, as this can strain the motor and other components. Clean the pump filter regularly to prevent debris from entering the motor area.

Expert Tip:

Some Maytag washers have a diagnostic mode. To enter service mode, press and hold the Start/Pause button while simultaneously pressing the Temperature Up and Temperature Down buttons. Release all buttons and then press Start/Pause. This allows access to diagnostic codes and component testing.

Frequently Asked Questions

•Where is the rotor position sensor located in my Maytag washer?

The rotor position sensor is typically located near the motor, usually attached to the motor housing or the stator assembly. Refer to the service manual for your specific model for the exact location.

•How do I test the rotor position sensor with a multimeter?

Disconnect the sensor from the wiring harness. Set your multimeter to measure resistance (ohms). Connect the multimeter probes to the sensor terminals. Refer to the service manual for the correct resistance range for your model. An open or shorted circuit indicates a faulty sensor.

•What is the part number for a replacement rotor position sensor for my Maytag washer?

The part number for the rotor position sensor varies depending on the model of your Maytag washer. You can find the correct part number by looking up your model number on the Maytag website or contacting a local appliance parts supplier.
