Motor Winding Test; Other Component Resistance Chart - Maytag MXR65 Service Manual

Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.

MOTOR WiNDiNG TeST

MXR20 - 65 motors have 3 motor winding
wires, 3 black, 1 green (ground)
1. Unplug washer or disconnect power.
2. To gain access to the inverter connections,
remove the rear panel, loosen the Phillips
screw securing the inverter cover, and
remove the cover.
3. Remove wire cover from bottom of the
inverter by gently squeezing in on the sides
and pulling it down away from the inverter.
4. Ohm test for shorted winding by checking
each motor lead to ground and the reading
should be an open circuit (infinite Ω).
5. Motor wires connected to inverter drive
and to motor junction box are marked
"1", "2" and "3" in all MXR20 - 65 models.
Resistance measurements are made from
"1" to" 2", "2" to" 3", and from "1" to "3" as
noted in the table below.
NOTe: Make sure the inverter wire cover,
and front cover and screw as well as any
removed wire ties are reinstalled or properly
replaced.
