I have the E3 error. I have 11.6 ohms on CN9
My washer will not make one rotation at all.
What else could is be?

What else could is be? Duane, You didn't do the resistance check correctly at the CN9 connector, from what you gave me. (unless that was one of the motor winding tests) ? At which point , you'd have a bad motor winding. There should have been 3 tests on the wires in the CN9 connector: Blue to White Blue to Red White to Red (you need to unplug the connector off the board and test the wires in the harness connector). And you should read 2.5 ohms resistance(+/- 10%) on each test. At the CN8 connector: (you need to disconnect the harness and test the wire pins in the connector) Orange to Blue Orange to Pink You should read infinite resistance. Blue to Pink You should read 4.7 ohms resistance If all these resistance checks are in the 10% range, then your motor and motor harness are within specification, and you'll need to replace the control board. If not, you'll need to check the harness to the motor, and replace the motor if the harness checks proper. Good Luck, :cool: :cool: :cool:

reading this thread I have run same tests and am hoping to get a response to my test numbers. tested control board and motor and have readings of 3.1 to 3.3 for all connections at both. did the additional cn8 test and i am getting absolutely no reading at all. from the post proper readings = replace control board and incorrect readings replace motor. i just want to be sure before replacing motor especially since i am getting no readings at cn8. Thank you.

Thank you. Sissom, You're on the right track, No resistance readings on the CN8 connector at the control board would indicate, A broken wire in that CN8 wire harness, A bad tachometer circuit in the motor. So, Check and make sure all the wires are intact, then replace the motor, if they are. :) :) :)

HI,
I am also having a similar problem.. (E3 error) Machine will attempt to increase speed but as soon as it starts to increase beyond 150 rpms it stops Machine will then attemtpt a few more times unitl finaly gives the E3 error).
Here are the measurements I got...After unpluging CN9 I measured the harness plug and got:
Blue to White = 2.3 ohms
Blue to Red = 2.6 ohms
White to Red = 3.0 ohms
I then unpluged CN8 and measured the harness plug..I got:
Orange- blue = 16.7 Megohms
Orange- pink = 4.75 Megohms
Blue to Pink = 4.75 Megohms
I then went further and measured the CN8 header on the PC and got:
Orange- blue = 2.3K
Orange- pink = 1.7K
Blue to Pink = 900 ohms
Can you please help me assess the problem? Thanks in advance.
Tonily

Tonily Tonily, You need to recheck your circuits again. Make sure your meter is set for 10K or 20K ohms scale, not the Mili ohms setting. Make sure the meter probe pins are in the connector solidly touching the interior pin. Your readings at the CN9 connector(motor windings) are in range (3.0 ohms) They all should have had the same resistance, but at this point it doesn't matter. At the CN8 connector, The resistance across the orange wire to blue or pink wires should have produced an "infinite" resistance reading (open circuit / no resistance). When you recheck with the meter set properly, if you still have a resistance reading, the tachometer circuit in the motor Part number: AP4044351
has failed, or the CN8 wire harness is damaged.

Thanks Joe, I tested with my fluke which has the auto range i use it daily for work...Not at home at the moment..question, is the speed sensor on back of the motor sold separately?
Once again thank you!

Once again thank you! Tonily, Unfortunately the tach sensor is not available as a separate component. If the circuits test bad (again) you'll need to replace the motor. Good Luck

OK, sorry to bring this thread back to life but i am need of some further insite, hopefully Joe or another knowledgable member can help. I have had trouble with my Maytag Neptune washing machine giving me a troublesome 3E code.
I tested the CN9 plugs with my digital meter set to the 20k setting and at each combination Blue to White, Blue to Red and White to Red, the meter jumps and then shows a reading of 0.00 (which I believe shows a short). However when I set the meter to 200 I get a readings of 2.7 at each combination. According to the manual for the meter the 200 setting has a resolution of 0.1 Ohm and the 20k setting has a resolution of 10 Ohm.
Further confusing me is that when I test the CN8 plugs with the meter set to the 20k setting I get a reading of 4.62 across the Blue and Pink wires and measured infinate resistance at the Orange to Blue and Orange to Pink tests. However if I set the meter to 200 I get infinate readings at each test.
I then proceeded to remove the motor and tested the pins again with the same readings at each combination as noted above, so I think the harness is good.
Based on the information I beleive that my meter must be set at the 20k setting and that the readings taken at the CN9 connector of 0.00 indicate a short at the motor and the motor needs to be replaced?
Any further insite would be greatly appreciated, thank you
