Whirlpool AWM 6163 motor / tacho fault?

P31 – the lower terminals should both look identical. The left hand terminal has pulled the connector out of its housing.

Don’t know if that will actually help or not.

Yes, the connector was a pest as I had to attach the wire at the same time as putting it together. Wasn’t too hard. Didn’t help though…

Are there any basic tests I can do on the MCU?

Re: Whirlpool AWM 6163 motor / tacho fault?

So, faced with no machine and not enough dough to buy a new one I decided to at least have a machine that spins by cabling the motor up directly but not even that worked. It behaved the same as in the machine. It would turn once and click and that was it.

This means however thats its not the machine, its the motor. First off I tested the cable. That was OK, then the armature to brush box and then the field coils. No connection from the no 4 plug pin to the field coil. Traced that back to what I suspect is a trip of some sort. Bridged that, reassembled. Worked fine. Put it back in the machine. Works fine.

Clucking bell! A result!

Now, this begs the question, why did the tacho go in the first place and what blew the trip and more importantly, when will it happen again?

Cheers,

Wilson.

Do NOT run the motor without the cut out – it isn’t safe. Buy THIS, chop the wires off and fit to the brush plate – just in case.

Did you get my PM? The parts I have look the same as the ones in your photos so might be worth a try. You need to check if the motor is sparking a lot at maximum spin speed. If it is, you have shorted turns in the armature and the motor is scrap.

Hi Phidom,

Thanks for the PM. I just got it.

We test ran the motor on the bench and obviously we didn’t let it run for any length of time but it did look good.

Anyway, I’ve sent you a reply to your PM.

Cheers,

Wilson.

Hi Mr. Penguin,

Am hearing you on FM. Will get part.

Any thoughts on what caused the trip to blow?

Cheers,

Wilson.
