I searched in the forum and most of the failures point to the wax motor and the controll board. By controll board looks percect and I get 120vac to the switch. I switched the sensor to appear the the door is closed and locked and the machine still will not do a high speed spin. What can it be???

Check your motor as well. Sometimes the motor or motor switch won't allow it to go into high spin

Motor & motor control testing: 1. Set the timer knob into the delay increments.
2. Press the push-to-start switch to start the
washer in the delay mode. Confirm the
delay light is ON.
3. Check for 120 VAC between the L and N
terminals (black wire no.27 and white wire
no. 13) on the motor control board. If not
present, check wiring between the machine
control and the motor control
boards.
4. Unplug the washer power cord. Test cord
to the same board terminals.
5. Remove JP4 Interface connector wire harness
on front end of motor control board.
6. Plug the washer power cord into a 120 VAC
power source. The motor control will immediately
execute a test routine and the
motor should run, rotating the spinner at 50 rpm. 7A. If the motor runs, and the spinner rotates
at the proper RPM speed, the problem lies
outside of the motor and motor control
circuit. Disconnect power to the washer
and reconnect the JP4 Interface connector
to the motor control.
7B. If the motor does not run:
A. Check the 10-amp fuse located on the
control board, either visually or with an
ohm meter. If bad, completely replace motor
control/wire harness assembly
(Figure 2-6).
Figure 2-6
B. If the fuse is functioning, visually check
the six semiconductors on the heat sink
for any damage. If damaged, replace motor
control/wire harness assembly complete
and check motor windings for damage
(See Drive Motor). Replace motor if necessary(Figure 2-6) .
C. If fuse and semiconductors show no
visible damage, perform the motor phase
test.
8. Unplug the washer power cord and replace
motor control board connector JP4
when finished.
Motor windings check:
1 . Disconnect power to the unit.
2 . Remove each pair of phase wires from the
motor control and perform an ohm check
of each wire leading to the motor. Each
wire pair should show 2-3 ohms resistance
(Figure 2-5).
2 . There should be no continuity between
any of the terminals and the frame of the
motor.
3 . Check that all six motor terminals are secure
and at the same height in the connector
housing. Replace motor if terminals
are pressed into the motor.
4. Remount the six-position motor connector
onto the motor. Reassemble the drip
shield cover onto the motor control.
5 . Reposition the motor control into the
washer when finished. Make sure the two
screws and the twistlock wire ties are fastened
properly to the wire harness.
Let me know what you find.

I did the test. There are 120v AC to L-N. Unpluged jp4 and the tub spins at 50 rpm. Still will not do a high speed spin. Can I jumper the power directly to the motor to get it to spin???
WHat else can it be

No it could burn out the motor completely. Looking at the manual again.

Just give me the basics on the test and I can do it. I guess there are three phases to check. What wire pairs and what ohms to you expect

The motor windings check is listed in the above in my 2nd post at the bottom.

How do I remove each pair from the motor control board?
