Title: Maytag Dryer works fine sometimes
Post by: Dhul on August 19, 2008, 08:12:55 AM
Hi,

I have to repair a Maytag Dryer (MDE model). When I select the time and press Start button, not always the machine starts to run. I can hear the motor trying to spin, but it doesnīt start.

If i keep the start button pressed more than 2 seconds, the machine stops and it looks like it goes into a protection state. I have to wait some minutes until I can try again. I suppose it is an thermal fuse to protect machine.

But sometimes, the machine starts to work fine ( a few times in a day ).

I think, I will give more details in a few hours. Anyone can help me?

Model MDE16MNAGW

Reach inside the drum and turn it. If it seems hard to turn then maybe you have rollers going bad.
The blower wheel will give problems.

Dhul, you will need a new motor. We would appreciate a complete model, not just MDE

Hi,

The exact model Iīll give you in some hours, I have to see it. I remember it is a Maytag MDE14xxxx. It uses 220v,50Hz. I suppose the motor uses a capacitor to start to run. Is it possible the capacitor is not well at all? Why does the machine works sometimes?

In a few hours I can give you the exact model number. Thanks

It does this because the motor is overheating. Bad motor bearings will cause this, and there is NO capacitor. The motor only uses 120 volts, the 240 is for the heater.

Be sure there is no foil duct on this machine. A bad venting installation will kill this machine over time.

It uses 220v,50Hz. The motor in that dryer is probably 220 volt repair man.we use 60 hz if that dude is a 50 hz then it probably hails from Europe and therefore takes a 220 volt motor.Non of these motors have a capacitor. They have a cent switch . The motor uses all of the copper to get going and then when the centrifugal switch's counter weights fly out they shut down the power to half the copper and allow the motor to run at half the amps as was nessesary to propell the motor forward in the initial effort.

JW, I did notice he said 50 hertz. It's the standard current in Eur. Thanks for your input and lesson on how a centrifugal switch works (in your own mind). Without a proper model number, you don't know that the motor is 220 volts for sure.

Hi again,

As JW says, the machine is in Spain, it uses 220v - 50Hz to work. I have the electrical schematic and i see the cent switch. Now I know what is it for.

Now I suppose I have to check the motor and the cent switch. The machine is some Km far and I have to see the exact model type to tell to you.

Thanks again.

Take a new motor with you so you don't have to make 3 trips, if it is so far away.

If you have the technology to send a copy of this wiring diagram, we would like to see it.

Hi,

I was wrong with the model of the dryer. The model is MDE16MNAGW. The electrical schematic and the electrical wiring diagram are in this pdf file.

Funny, I can pull up this model, but it shows an electric dryer, not a gas one as you showed us. I guess trying to cross-reference some of these machines is going to prove interesting.

I still maintain that the motor is bad.

I canīt see a service manual for MDE16MNAGW in the Downloads section. Where can I find a service manual for this machine?

There's no manual in our arsenal to cover 50 hertz equipment. If it's any consolation, I found out that the motor on this model has a separate centrifugal switch, part #33002451. I would opt for this before I replaced the whole motor.


Although this manual is for our models (http://appliancejunk.com/forums/index.php?action=store;sa=view;id=99), the structure of the dryer is the same, minus the transformers, etc.

Check it out : the door switch may be intermittant. I have seen this switch act up on these dryers: http://www.repairclinic.com/SmartSearch/SSPartDetail.aspx?PartID=517075&PPStack=1 Notice the big old MEXICO written on the bottom? That should splain it.:D

Nice thing to say to a Spaniard, JW... ::)

We should remember why those parts are made where they are:
