Title: Maytag MDE4000AYW dryer will not rotate
Post by: robpmorrison on May 25, 2012, 09:07:28 PM
We bought this dryer back in Sep 1999.  It has been excellent and we have not had any problems with it for the past 12.5 years.  I have pulled the front off of it every couple of years to make sure all the lint is cleaned out of it.  It was working through last Saturday night.  On Sunday morning the start button was pushed again and all it would do is buzz and the tumbler would not move.  I can move the tumbler by hand with force so I am assuming the belt is still in place.

I have been doing some reading and from what I am finding it could be either the motor or some sort of fuse or relay connected to the motor.  However I have not found anyone who has described exactly what I am finding with this dryer. 

I realize that I can make a cable to plug the dryer motor in to see if it runs and I may do that tomorrow.  I would just like to get it fixed for my wife.

I videoed what it is doing this morning when you push the start button.  Please go to here in order to veiw it http://youtu.be/zAsl6sXyQAQ

Thanks

Rob

BigBuck, Thanks.  I tried it again today and it started to turn but it took a bit so I am sure you are right when it comes to the starter. 

So I am going to change out the motor.  Now here is another question.  I have gone to several sites and there are 3 different part numbers for this motor that are coming up for the MDE4000AYW Neptune dryer.  They are 33002478, 33002795 and 33002462.  Does anyone have any ideas of which one would be the best one to buy?  They all seem to be the same price.

I haven't pulled the dryer apart yet so I will also do that to see what the actual motor may have on it for a part number.

You will need to go by the first two digits of the serial number to figure out the correct motor to order.

Post the first two digits of your model number if you are not sure.

You could also double check the part number on the original motor.
Post the part number of the original motor here if it don't match one below and will see if it crosses to another number.

Serial number starts with 28 order dryer motor part # 33002478   


 
Serial number starts with 55 order dryer motor part # 33002795

AJ thanks for the point on the shaft.  These two motors are definitely different.  I am guessing I will need to pull it apart to fully verify.

That would be a good idea.
Let us know the numbers posted on the motor.

If none of the numbers on the motor match the numbers I posted it maybe a old part number and I can double check the old number against the new part numbers.

It will be a bit before I can pull it apart today.  I will post what I find later.  Maybe I will make the cord so I can also fully test the motor as well.

Title: Re: Maytag MDE4000AYW dryer will not rotate
Post by: robpmorrison on May 29, 2012, 07:55:44 AM
AJ,

Here is a follow up.

1. I was able to run the dryer a couple more times and then at one point when I pressed the start button I got the buzz to start it and then it stopped and I got a smell that something went.  Would that only be the starter on the motor or could it be something else.

2.  I pulled it all apart.  There really is not a lot to these dryers.  The fun part will be putting the belt back on the drum from what I can tell.  Attached is a picture of the motor.  The p/n on the motor is 63709530 and the model # is S58NXMPM-6852.  These are different than the part numbers you find anywhere else.  I am going to guess that the part # 33002478 is the correct one because of the flat spot on the shaft.  It is a 1/4 HP, 1 phase, 115 V, 60 Hz, 4.5 Amps, 1725 RPM, MFG date code is F99A5.  See the pictures.

3.  I used my digital multimeter to ohm out the switch on the motor.  The service manual says that between terminal 3 and 4 there should be 3 ohms and that between terminal 4 and 5 there should be 2.25 ohms.  I found the following:

Between 3 & 4, Motor shaft switch relaxed 3.1 ohms, with the motor shaft switch depressed 1.8 ohms

Between 4 & 5, Motor shaft switch relaxed 3.3 ohms, with the motor shaft switch depressed 1.8 ohms

Do these motors come with these switches mounted?  I looks like it by the pictures but I do want to make sure.

OK if you have any thoughts and can verify if possible that the 33002478 is the replacement motor for this dryer than I will order up a motor.

Also would you recommend that I replace the two wheels that the drum rides on in the back at this time.  I can see some of the rubber from them dropping and they look warn.  It has been over 12 years that this has been in use without any problems and there is no telling the amount of time that they have been rotating.  We are a family of 5 and the dryer has been used a whole lot over those years.

Would you recommend I replace anything else while I am at it?

Thanks

Rob

Most likely the motor, I don't know what else it would be.

Yes, the switch comes mounted to the motor.

Should be the one. Also keep in mind that if you order the motor from one of the links I posted above the return policy is excellent.
You have 365 days to return any part ordered through our site. Any part can be returned for any reason, even if it had already been installed.

Would not be a bad idea to replace the two drum rollers.
Also look at the glides that the front of the drum ride on.
How does the belt look?

AJ,

Thanks for the input.  here is a link to the photos for the rollers for the drum support plus the belt and the drum bearings and I also took a picture of the idler wheel.

you can find the pics here https://picasaweb.google.com/116078893095334358419/DryerRepair?authuser=0&feat=directlink

What is your opinion on these things?  The belt seems to be starting to see shreads on the edges.  The bearings look like they are worn to me.  The rollers are as I said in my original post having rubber dropping off of them which can be seen in the pictures as well.  I wonder also if the idler wheel should be replaced or is that pretty solid?

Thanks

Rob

Post by: AJ on May 29, 2012, 09:07:24 AM
They all look normal in your photos.
Replacing any extra parts is more or less going to be a preventive maintenance thing.


The drum support rollers are pretty heavy duty on this model, but it's often the one above the heater that I find gives problems.
I think it's because of the extra heat it gets from being mounted above the heating element.


So the preventive maintenance thing is up to you. Just depends how much extra money you want to stick into it.

Title: Re: Maytag MDE4000AYW dryer will not rotate
Post by: robpmorrison on May 29, 2012, 09:10:08 AM
I guess it will depend on how much they all cost at the end of the day.  So I will do some cost analysis and then look at the budget.  It looks like the motor is the big ticket item to me.  But of course that is less than a new dryer.

Thanks

If it was my dryer I would replace the motor, two rollers and the belt.

Post by: theoldstoveguy on May 29, 2012, 01:02:46 PM
I look for cracks on the ribs on the belt, rollers lube unless real worn(worn bearing not rubber) and the blower only if it has play in the D so to speak on the motor shaft. It will rock slightly as you hold the blower and turn the motor shaft, if so replace. I have only changed 2 idler pulleys in 33 years so usually lube. Glides if they are thin.

When i started out 30 some yrs. ago, my grandfather said when i was putting grease or oil on the rollers to stop the noise, he yelled @ me & said, do not lube or grease rollers. He said that it would collect lint faster & seize them up faster. Was he right or wrong, I try not to oil or grease since then. I been sanding down with emory cloth & replacing rollers. I would think a little grease would not hurt.

I never use grease,always use Royal Purple Synthetic oil. I have for years and it works better than zoom spout turbine oil.

Is there any particular type of Royal Purple that you use?  I was looking at their website and their products.  should I use this MAX-TUFF SYNTHETIC ASSEMBLY LUBRICANT or is there something else I should use?

Thanks

Never have used royal purple. I use Zoomspout oil because it is used in the appliance industry and is safe for all major appliances and HVAC. It has been around forever and is inexpensive $3 for a bottle at any Ace hardware store.

Post by: theoldstoveguy on May 29, 2012, 07:46:02 PM
Last time I bought 6 bottles and the guy I got them from quit selling it. The Max Tuff bottle looks just like the stuff I bought. Mine says for guns, air tools, and fishing equipment. To give you an idea, you never oil a squeaky hinge on a house door as you will always have to oil it every month or so. 4 years and still no squeak. I always used zoom spout but I Will never go back as it can't compare to this stuff. I found it by mistake looking for synthetic oil for my truck. ( Isn't EBay great) Guy would send a bottle to a soldier in Iraq for every bottle sold, so I tried it. 3 of the servicers in my area use it as well. Holds up to heat very well.(Maytag dryer rollers)  I have oiled rollers on dryers and been back 2-3 months later with zoom ,oiled with the synthetic and never go back. You might contact the company and see if they make the liquid not spray can for guns.

Post by: robpmorrison on May 29, 2012, 08:57:34 PM
They have this which is a spray can for the items you noted http://www.royalpurple.com/product-categories/other/#!royal-purple-synthetic-gun-oil

Then they have this for air compressors http://www.royalpurple.com/product-categories/other/#!synfilm-recip-100-reciprocating-air-compressor-oil

This is the Max Tuff stuff http://www.royalpurple.com/product-categories/other/#!max-tuff-synthetic-assembly-lubricant  They recommend this for engines etc.

Then this looks interesting http://www.royalpurple.com/product-categories/snowmobile/#!maxfilm-multipurpose-synthetic-lubricant

I am assuming that It has to be one of these that you use.  Do you still have a bottle kicking around that you could take a look at?  If you do and are willing to look at it and come back to me with what product it is that would be great.

I called the local stores that Royal Purple is sold by but neither of them had much product and told me that I would need to tell them what to order.

Thanks for the help.

Rob

It's Synfilm got it from Burdick enterprises in Alaska?,(907) 262-3210 They no longer sell on EBay. If all else fails would look for 5W20 motor oil as it is very thin.

It will rock slightly as you hold the blower and turn the motor shaft, if so replace. I have only changed 2 idler pulleys in 33 years so usually lube. Glides if they are thin.

I checked the blower on the motor shaft and it does have play back and forth and you can see how it is worn.  So I will replace it.  However there are two different blowers and I am guessing that that is because there are 2 different motors with different shafts.  My motor is the 33002478.  The 2 part #'s for the 2 blowers are 33001790 and 33002797.  I think that it is the 1790 because it looks like that has the D shape for the shaft where the 2797 does not look that way but looks like you have to put a nut on the end of the shaft.  However it is better to be safe than sorry.  Is it possible for someone to verify which part number would work properly with my setup?  Thanks

Just to repeat my s/n for my unit is 10632471QW and it was purchased in 1999.

Their is no diff in shaft size on them blower wheels. The dif is the diameter and the size of the blades themselves. Some models carry a wing that is attached to the front of the assembly to act as a helper in aerodynamics I guess. Others do not have this wing attached to the front of the blower assembly. If this was an attempt to divert heat from the hub it was not very successful. LOL I have found that the cheapest offering of these wheels will work if the said diverter is omitted.

Did you look at the motor photos at the beginning of this topic?
One motor has a threaded shaft and the other motor has the D shaft.

Each motor uses a different blower wheel.

Thanks, I have been to that page already.   I run a business and we ship via UPS as our standard carrier.  I know that if I ship ground within a certain geographical area that it will get there in 1 day.  I'm in NJ so I am trying to determine where the parts will actually ship from so that I can determine what I should choose for shipping.  And of course I need to know if it will ship actually by UPS or if it will ship by some other carrier which will help me to determine the time as well.  I want it all to arrive on Friday since I am leaving for a business trip tomorrow to CA and will be back Friday night.  That way I can install everything on Saturday so that it can be up and running for the wife again.
