Adc 285???

[amartlock]

I have a stack that is the model prior to the ADC 330 (I think it's a 285 but I'm not sure). Anyway, the top dryer runs/tumbles for about 5 seconds and then stops tumbling. There is no error on the LED and the timer continues the count down. I shut the power down and the restart and it does the same thing. I just noticed the problem this morning so I haven't had a chance to open her up but I'm wondering if any of you have experienced this and can point in the the right direction to begin with.

Thanks for all your help!

The 285 is a single so that is not what you have. You either have a bad motor or something that is breaking the connection to the motor. It would help if you could tell us exactly what machine you have rather than just the "previous model" as the 330 has been around pretty much as long as stacks have been in existance.

It looks similar to the ADC 330 (except older), it has the big spinning wheel in the back rather than the belt around the drum. I don't have any manuals for it which is why I don't know the model. Someone once told me that they could have even been manufactured under the Primus name before ADC bought Primus dryers.

ADC didn't "buy" Primus dryers but rather at one point they were made for them.
I believe the dryer you are talking about is a AD235 or a AD230. Either one uses the same motor. Now you will need to do a little investigation, like checking the motor to see if it is overheating or if there is power to it when the dryer stops turning. I cannot do it for you over the internet.

You can't do it over the internet? I thought the internet made everything possible.

"Virtual repair" ... sounds like a viable solution to me!

First place I would start is check the door switch.

Like I said in my original post, I just noticed it yesterday morning but didn't get to check anything as I had to go to my real job. I'm going in for my weekly repair party Friday night. The first thing I plan to do is take the belts off and run it. This should tell me if it's the motor, ie, I hear grinding or something. Then I'll check the door switch and proceed from there.

Yes, It is most likely the motor is over heating. Do like MSK said When it stops...check across the white and black wires going to the motor for your 120 volts or Red and Black wires 208volts and higher If you are getting your Line voltage 120, 208.... and the motor is not turning it is bad.
Let us know, how you make out.

Would the motor overheat in a matter of seconds? When I first noticed the problem, it was before the store opened in the morning so the motor would have cooled overnight. Then when I started it, it ran for a few seconds then stopped turning.

What is a good source to buy a motor?

My amigo if you used the search engine here and typed in motor or motors or what you are looking for you shall find.

The tools are here use them I see many like you who want a sliver spoon. Join us on the Premium member.

Coinwash is the best thing that the real Laundromat want to be or owner has.

Now it’s good to ask questions but do your home work and research. It really works.

Use the search then ask your questions.

I messed around with the stack (ADC235) that is giving me problems. When you push the start to begin the dry, the tumbler turns for 3-4 seconds and then stops and it trips the breaker. I don't think the motor is overheating since it's only running for a few seconds and there is no grinding sound typical of a motor that's "going bad." My thought is an electrical problem but I have no idea where to start looking. Is it a thermostat? Is it the board? Any help on where to start part swapping is greatly appreciated.

Take a look at the wiring diagram, and start disconnecting individual circuits.

I had a washer (a 15-year-old Unimac UC50) that suddently began blowing a fuse every time I started it. I started disconnecting things, one at a time, and attempted to start the machine each time, and then replacing the fuse after each one: the motor, the water valves, the timer, the door lock controls, etc. I used up a half-dozen 50-cent fuses, but I eventually isolated the problem. A tripped circuit breaker is less expensive than a box of blown fuses, but you can do the same thing.

I finally discovered that when one of the two microswitches in the door lock mechanism was unmounted but left in the circuit, the machine ran without blowing a fuse. I replaced the switch ($4.50 at the local electronic parts store) and the machine has been running for a week without blowing another fuse.

FYI.....I pulled out the motor over the weekend and switched it with another dryer. Problem solved, or at least diagnosed as the dryer now works properly. I then talked to my local distributor/repair guru and he said that since it would start up fine and after a few seconds stop and trip the breaker, it was either the switch inside the motor or the run windings.
