Inverter

The inverter receives commands from the control

board and controls motor operation.

For the inverter to operate the motor correctly
requires a supply voltage of 120 VAC, DC input from
the control board, and the three motor windings
intact.

6SHFL¿FIDLOXUHVDVVRFLDWHGZLWKWKHLQYHUWHUFDQ

initiate fault codes E4A, E4B, E4C, E50, E52, and E54.
(See the Service Test Mode section in this guide.)

To check the inverter:

1. Remove the service panel. (See the Washer

Components, Service Panel section in this
guide.)

2. Press the 4 tabs inward and remove the junction

box cover.

3. Enter test mode t10, t11, or t13.

4. Check for 120 VAC between the blue and red

wires at the AC input harness.

NOTE: The 120 VAC inverter supply voltage is
present only when the motor is supposed to be
operating.

5. Unplug washer, then check motor resistance.

(See the Washer Components, Motor Assembly
section in this guide.)

6. If 120 VAC is present at the AC input harness

and the motor resistance is correct, replace the
inverter.

NOTE: If the inverter overheats, the washer will stop
for 5 minutes.

The Separate Inverter

The inverter is enclosed in a protective housing and

is located on the chassis, under the left side of the
outer tub. It is inserted in 2 guides at the rear and
held in place by a single Phillips head screw at the
front.

Inverter Removal

1. Remove the service panel. (See the Washer

Components, Service Panel section in this
guide.)

2. Press the 4 tabs inward and remove the junction

box cover.

3. Disconnect the AC and DC input wire harnesses

from the inverter.

4. Press the lock tab and remove the motor ground

wire.

5. Remove the plastic wire tie that holds the motor

wiring in place.

6. Remove the single Phillips head screw that holds

the front leg of the inverter to the base pan.

7. Slide the inverter rearward to clear the guides

that hold the rear of the inverter to the chassis.

Remove the inverter through the enlarged opening
on the left side of the front frame.
