How to Troubleshoot & Replace Whirlpool AP6008708 / WP354987 E Ring

First replaced the drum rollers...that wasn't it..took dryer back apart and spun the belt tension wheel by hand (should have done this the first time I took the dryer apart) and it squeaked. so I ordered the full parts: wheel, idler arm, idler spring, arm sleeve, E ring..Put it back together and whoa..no more squealing!! 

It took me about 2 hours to take everything apart and get it back together & running again with no problems. All the parts I ordered were exactly what I needed to fix everything. Thank you all !!! 

Replaced the belt and idler pulley. The job was bigger than I expected. Had to take the whole dryer completely apart, because there wasn't an access panel on the back. Other than that the job went smoothly. 

Replaced drum support rollers and bearing wear pads. 

Removed panels to assess what needed to be repaired or replaced. Used the diagrams, for my model of dryer found on AppliancePartsPros web site. All required parts were in stock. Once ordered, parts were shipped and I received them within a few days. All the parts were genuine, not cheap knock offs and the order was correct. Nothing missing or wrong. 

I noticed my dryer gradually started making noise as time went in. After seeing your videos I decided to take the project on rather than. Very easy fix. Replaced the gliders, support rollers and drum band. Cleaned out the dust and it works great. My washer was acting up at the time. Not so lucky on that one. Thank you appliance parts pros. 

Ordered parts for a 25 year old Maytag gas dryer..no problem in getting parts,.the web site for parts are great It cross references to other parts so you can order the parts. or suggestion on what you may need to do..I didn't have to take the dryer totally apart from the front..as if you would repair the drum roller for which I did a few time ..just pull out dryer from wall disconnect the gas and power suppley..open the small 8 x8 panal on backside where the motor is located , take old parts out replace will new parts down. reconnect everything..Than done ..It took me 20 to 25 minutes to do the job..My skill level is very good. If I would get a repairs person to do it. I would have to take the dryer to than and the cost would be over $200. Besides if you have anything that more than10 years old no one will repair it. So I save over $!00.. By doing it myself 

Replacement along with belt and drum rollers. 

Replaced drum support rollers, belt tension idler, and belt 

Ultimately is was discovered and caused by the blower wheel shaft opening was cracked and broken. Replaced blower fan wheel.
