So since November 29 the washer has been working fine till today. Now, the motor does not move at all. The timer moves forward OK.
So back to the Tech Sheet steps for motor does not run
Step 1: The drain pump runs go to step 2.
Step 2: If the motor does not run go to step 3.
Step 3 Remove the four pin plug from the speed control unit. Measure the voltage drop between pins 2 and 4. If the meter reads 0 check the motor thermal cut out. Which has 0 resistance and the specifications is for less than 1 Ohm.
What's next then?
The motor resistances for tachogenerator (pins 1 & 2 - measure 134.8 Ohm vs spec of 135 Ohm) and stator winding full field (pins 3 & 4 - measure 1.3 Ohm vs spec of 1.26 Ohm) are OK. Except for the armature windings (pin 5 & 6) that is infinite and should be less than 5 Ohm. It is measured at the contacts after pulling out the plug. But I had the same measure previously till I actually measured it on the motor side, which just requires that you pull the motor out. And I have not yet measured the stator winding tapped field, but the full field is fine.
On the speed control board. The voltage between pins 9,6 & 4,4: 0 Volts. pins 9,3 & 4,4: 0 Volts. pins: 4,1 & 4,3: infinite resistance.
