Inverter

The inverter receives commands from the control

board and controls motor operation. 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.

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.

Speciﬁ c failures associated with the inverter can

initiate error codes E43, E4A, E4B, E4C, E4E, E4F, and

E53. (See Service Test Mode.)

To check the inverter:

Remove the service panel. (See Service Panel.)

Press the 4 tabs inward and remove the junction

box cover.

Enter test mode t10, t11, or t14.

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.

Unplug washer, then check motor resistance.

(See Motor Assembly.)

If 120 VAC is present at the AC input harness and

motor resistance is correct, replace the inverter.

Note: If the inverter overheats, the washer will stop

for 5 minutes.

(Continued Next Page)

Disconnect the motor wire harness.

Note: The motor wire harness is soldered to the

inverter. Any fault in the inverter or motor wire

harness requires inverter replacement.

To remove the inverter:

Remove the service panel. (See

Service Panel.)

Press the 4 tabs inward and remove the junction

box cover.

Disconnect the AC and DC input wire harnesses

contained in the junction box.
