How to Troubleshoot & Replace Whirlpool AP6024088 / WPY014874 Appliance Fastener Screw

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 !!! 

At first i just bought the belt, started dryer and off came the belt, and yes it was in place,looking at the idler arm it had a lot off back and forth movement so i ordered the whole assembly but the spring which no one has.put it all together again but drum barely turned.. so back apart and belt was in place. took the idler spring out cut 4 loops off it re did the end so it would hook on idler arm.and that did the trick.runs like new. 

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 

Replaced drum support rollers and bearing wear pads. 

This dryer is roughly 40 years old and started life as a coin operated dryer. I got it in 2001 and have not had to do anything till this month. These parts were not the problem but I changed them. The idler arm sleeve was a little thick. I sanded it down thinner. The idler pulley arm I bought to check sizes or holes. To check for wear. There wasn't any.The belt I changed as it was just starting to fray. The blower fan was making most if not all the noise. It was cracked and the hole in the middle was worn oblong an made it wobble a bit. 

Replaced the drain pump. 

Replaced the pulley assembly and belt. This unit is 16 years old and now has new life. 

The repair took a few minutes, I was familiar with the inside of my dryer because last month the drum rollers needed replacing. Thanks to your repair videos and ease of ordering and accurate part delivery everything was really simple. The parts arrived in two days as promised, Thanks! 

Replaced the puller wheel and washers. 

Had to replace the idler arm because the bushing hole was wallowed out.
