Question about Dryers

Popping noise, like pop corn

I have a Maytag DG712 dryer. It sounds like it is popping pop corn. I replaced the drum belt & idler pully. The shaft for the idler pully was shiny no wear and I put bearing grease on the shaft. I thought I fixed it. It was sounding good. But now it's worse than ever. It seems to me to be coming from the motor area. The exhuast air is a strong flow. So could it be a bad motor/bearings, or blower wheeel? Appreciate your help! Thank You, David

You may want to open up the blower wheel housing in the front part of the unit there may be an obstruction in there or a loose blower wheel .Try to move the blower wheel by hand and see if it is loose.If that does not work you may have an object in the inner drum fins or the three tumblers in the the drum.To remove them you need to lift the top and use a 5/16 nut driver .Hope i fixya :)

When the rollers start moving there is a loud popping noise. any ideas?


By "rollers" if you are referring to the drum turning, it could be a lot of things. The drum itself turns on two rollers located at the back of the machine and is held in the front by a felt ring (all around the front opening. A belt is wound around the drum and connects to the motor pulley usually tensioned through an idler pulley.
A popping sound leads me to believe that either one (or both) of the rear rollers is defective, the felt ring needs to be replaced or possibly the belt idler is defective. (I'm guessing, but I 'm thinking that the drum is binding due to a defective support roller or felt and the machine needs to overcome this bind before it can turn. The motor starts to turn, the belt pulls and begins to bunch up until it overcomes the binding and then as it snaps back, caused the pop you hear.)
What I would do is remove the front of the dryer (usually two screws located on the front cover, down near the floor, then swing it up from the bottom until it unhooks at the top) and turn the drum by hand to see if you can locate where the sound is coming from. Its actually very easy to do this, but make sure to remember to unplug the dryer before opening. There are discount supply houses on line that can ship you new parts. I usually use repairclinic.com, but there are others.

How do you replace drive belt on maytag gas dryer


Hi david lebron
This solution is for an electric dryer, but the gas dryer would be the same.
***************************************************************************
ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Sounds like your problem may be the belt may have slipped off of the motor pulley, or idler arm pulley and/or you have noisy drum rollers.
Note: This method works for most front loading machines.
If you have to check/replace/repair your drum motor,drum seals,belt,rollers, etc.
If replacing drum seals be sure to use a good grade of weather proof cement to hold the seal/s in place, some seals are furnished with the cement to glue it in place.
Remove the electrical console that holds the timer switch,start switch, etc. from the top of the dryer if necessary. Be real careful not to knock any of the wires off of the timer switch or other electrical connections.
Remove the lint filter and the two screws that hold the filter housing to the top of the dryer lid.
Then remove the top of the dryer by inserting a screwdriver between the top and frame on each side of the dryer to pop the lid up from the retaining clips.
Note: Some of the tops tilt backwards on a type of hinge and do not have to be removed completly.
Remove the front of the machine by disconnecting the door switch and removing the two screws located on either side of the dryer frame.
Move the door and front of machine forward to remove.
This will expose the belt,idler bracket and drum, remove the drum and belt and this will expose the drum rollers, idler arm bracket with pulley, and motor with pulley. Pay attention to the route of the belt, this will come in handy when you go to reinstall the belt and drum.
Sometimes the belt will slip off of the idler arm or motor causing the drum not to turn.
Note:The way the belt goes back on is, as the belt comes off the drum has to be doubled (pushed together to form a loop) and goes under the idler pulley then to the motor pulley.
Here is a link to see a picture of your belt routing in case the belt is broken when you open your dryer:
http://www.expertappliance.com/dryerbeltconfiguration.html

While you have the drum out, I would recommend that you remove and lubricate the drum rollers.
And also clean the shafts of the rollers as they will collect hair,dust,etc and cause problems and then lubricate the shafts and rollers with a good grade of machine oil like 3 in One oil or a vasoline type of lubricant. This will save you a problem later with the rollers getting dry and making a squeeling noise, also check your drum rollers for flat spots, if they have flat spots on them this will cause a thumping type noise.
You will need to replace the drum rollers if they have flat spots on them.

Hello,

This link here http://www.repairclinic.com/Dryer-Belt-Diagrams shows the proper configuration of how the belt fits onto the motor/idler pulleys perhaps this will help you to keep the belt on by checking thats its properly on the motor&idler pulleys. Just find your brand and veiw the diagram.

My Maytag dryer makes an awful screeching sound when I start the dryer. It still dries the clothes, but I can't stand the noise.


your rollers or belt idler is corroded. you need to take dryer appart and lubricate the parts in question with MINERAL OIL or SPECIAL BEARING LUBRICANT. """"DO NOT USE WD-40 OR 3 IN ONE OILS"""". good luck to you.

How to put belt back on drum on my dryer


You have to take the back off of the dryer and see the motor pully and the idler pully. slip the belt around the drum, around the mototr pully and usind a flat blade putty knife, work the belt over the idler pully so that it puts tension on the belt. you may have to loosen the idler pully housing bolts, but try it first with working it over the idler as that was set for optimum tension.

My maytag atlantis dryer is making a loud squeaking noise. sounds like metal on metal. possibly a bad bearing? any ideas...


ALWAYS UNPLUG YOUR DRYER BEFORE STARTING ANY REPAIRS
Your problem sounds like drum rollers have flat spots on them or in need of lubrication, or maybe your drum belt has slipped off of the idler arm pulley.
If you have a front loading machine,

Remove the electrical console that holds the timer switch, start switch, etc. from the top of the dryer.
Be REAL CAREFUL not to knock any of the wires off of the timer switch.
Then remove the top of the dryer.
Remove the front of the dryer. This will expose the drum and belt.
Remove the drum and belt and this will expose the drum rollers, idler arm
pulley and motor.
Now is a good time to check the belt to see if it has slipped off of the
idler arm pulley and also to check the belt condition for wear.
Be sure to note the route of the belt, this will come in handy when you go
to reinstall the belt.
Check your drum rollers for flat spots or wear, if they have flat spots
or wear on them replace them.
If the drum rollers don't have flat spots or wear on them then they probably
only need lubrication. Lubricate the shaft of the rollers with a good grade
of machine oil such as 3 in One oil.
Reassemble the dryer, plug back in. This should solve your noise problem.

My dryer drum does not turn during drying. The belt is not broken and the dryer is heating the cloths. Why has the drum stop turning?


You could have a faulty motor, or maybe the belt has slipped off of the idler pully or motor pully

ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Sounds like your problem may be the belt may have slipped off of the motor pulley, or idler arm pulley, or maybe a faulty motor.
If you have to replace your drum belt and if you have a front loading machine.
Remove the electrical console that holds the timer switch, start switch, etc. from the top of the dryer some slide off.
Be real careful not to knock any of the wires off of the timer switch.
Then remove the top of the dryer,some are clipped on,others slide off.
Remove the front of the machine, this will expose the belt and drum, remove
the drum and belt and this will expose the drum rollers, idler arm bracket
with pulley, and motor with pulley.
Pay attention to the route of the belt,this will come in handy when you go

Sometimes the belt will slip off of the idler arm or motor pully causing the drum
not to turn.
If you cannot find the proble there, then maybe the timer switch is faulty and needs replacement.

Drum not spinning


sound like the rear bearing is stuck and the noise is the belt slipping on the idler pully and rear bearing needs replaced

Drum not spinning


Pretty easy fix. start by popping the top
bfce1c6.jpg
Once you get that up then remove the front. The rear hatch gives access to the idler assembly, look in there to see the status of the belt before popping the top. The bumping could have been from a bad st of glides on front or a bad bearing on back. Impossible to tell till ya give it a look see.
