Roper Washing Machine Error Code oL: Oversized Load... | appliancefaults.com

Technical Background:

The MCU monitors the motor's current draw and rotational speed. If the current exceeds a pre-programmed threshold or the motor struggles to turn, the MCU interprets this as an oversized or unbalanced load, triggering the 'oL' error. The voltage path from the outlet to the MCU and then to the motor must be uninterrupted for proper operation.

Symptoms:

The washing machine displays error code 'oL' or 'OL' on the control panel and stops mid-cycle. The drum might be partially filled with water, and the machine may be unresponsive.

Possible Causes:

Excessive laundry loaded into the washer.
Load is unbalanced and causing the motor to strain.
Faulty load sensing system.
Defective motor control unit (MCU) or motor.
Foreign object obstructing the drum's rotation.

Solution:

1

Unplug the washing machine from the outlet.
2

Manually remove some of the laundry from the drum to reduce the load size.
3

Check for any obstructions in the drum, such as clothing or small items caught between the drum and the outer tub.
4

Inspect the motor and motor control unit (MCU) wiring harness for loose connections or damage. Use a multimeter to check the motor windings for continuity. A typical resistance value is between 3-6 Ohms.
5

Verify the voltage to the MCU. Use a multimeter to measure the voltage at the power input to the MCU. You should see 120V AC.
6

If the wiring and motor check out, the MCU may be faulty and require replacement.
7

Plug the washer back in and run a test cycle with a smaller load.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Lock-out/Tag-out (LOTO) procedures should be followed. High voltage is present when the appliance is plugged in.

Prevention:

Avoid overloading the washing machine. Refer to the owner's manual for recommended load sizes. Distribute laundry evenly in the drum to prevent unbalancing. Regularly inspect the drum for foreign objects.

Expert Tip:

Access the service mode by pressing and holding the Start/Pause button for 3 seconds, followed by pressing the Power button. Then, navigate the diagnostic menu to clear the error code and run a calibration cycle to reset the load sensing parameters.

Frequently Asked Questions

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

The diagnostic mode can usually be accessed by a specific sequence of button presses, often involving the Start/Pause and Power buttons. Refer to your washer's service manual or search online for the exact sequence for your model.

•What is the typical lifespan of a washing machine motor?

The typical lifespan of a washing machine motor is around 8-12 years, depending on usage frequency and load sizes. Regular maintenance can extend the motor's life.

•Where can I find replacement parts for my Roper washing machine?

Replacement parts can be found at appliance parts retailers, both online and in brick-and-mortar stores. Be sure to have your washer's model number handy to ensure you get the correct parts.
