Amana Washer Error Code F7E2: Drive Motor Over... | appliancefaults.com

Technical Background:

The MCU monitors the drive motor temperature via a thermistor. The MCU controls motor speed and direction. If the thermistor reports an over-temperature condition, the MCU halts motor operation and displays the F7E2 error.

Symptoms:

The Amana washer displays error code F7E2 and may stop mid-cycle. The motor may feel hot to the touch, or the washer may refuse to start a new cycle.

Possible Causes:

Overloaded washer tub exceeding motor capacity.
Blocked or restricted drain pump creating excessive motor load.
Worn motor bearings causing increased friction and heat.
Defective motor thermistor providing false temperature readings.
Faulty motor control unit (MCU) causing incorrect motor operation.
Obstruction in the drive system (belt, pulley)

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Allow the motor to cool down for at least 30 minutes.
3

Inspect the washer tub for overloading. Reduce the load size for future cycles.
4

Check the drain pump for any obstructions. Remove any debris (lint, small objects).
5

Test the motor thermistor using a multimeter. Resistance should be within manufacturer specifications (typically around 10k ohms at room temperature). Replace if faulty.
6

Inspect the motor windings for shorts or open circuits using a multimeter. Replace the motor if windings are damaged.
7

Verify the wiring harness connections to the motor and MCU are secure and free from corrosion. Re-seat connectors.
8

If the above steps do not resolve the issue, replace the motor control unit (MCU).

Safety Warning:

Disconnect power to the appliance before performing any repairs. High voltage components are present. Use caution when testing electrical components. Lock Out Tag Out (LOTO) procedures should be followed.

Prevention:

Regularly clean the drain pump filter to prevent clogs. Avoid overloading the washer tub. Inspect the motor belt for wear and tear and replace as needed.

Expert Tip:

Enter service mode by pressing and holding the Start/Pause button for 3 seconds, then rotating the cycle selector knob clockwise three clicks, then counter-clockwise one click, then clockwise one click. This will allow you to run diagnostic tests on the motor and other components.

Frequently Asked Questions

•What is the correct thermistor resistance range for this Amana washer model?

Refer to the Amana service manual for the specific resistance range of the motor thermistor at room temperature. It's generally around 10k ohms, but can vary slightly.

•How do I access the motor control unit (MCU) on this model?

The MCU is typically located behind the control panel. You will need to remove the top or rear panel of the washer to access it. Disconnect power before accessing the MCU.

•What are the recommended torque specifications for the motor mounting bolts?

Refer to the Amana service manual for the recommended torque specifications for the motor mounting bolts. Over-tightening can damage the motor or the frame.
