I ordered pulley 6-3037050 for my Maytag dryer. It looks different than the original one that melted. Will this pulley work or do I need 6-3700340? I should have checked here first. According to another site this was the right pulley for my dryer. Maytag Neptune MDG&460AWW Dryer. Thank You.

It's funny to come back to this site and found my note from previous visit to be useful. http://forum.appliancepartspros.com/dryer-repair/167200-how-replace-dryer-belt-mde9206ayw.html Now it's back to the same problem. The dryer belt some how came off the tension pulley. I hooked it back in place and turn on the dryer. The tumbler spinned, but I noticed that this tension pulley was not spinning. It stuck in place and belt and get pulled around it. I can't imagine this is correct, right? This pulley should spin also right? I specifically tried to spin the pulley before hooking the belt back on it and it wasn't budging. Do I need to replace this? do I need the pulley arm (AP4373246) and these other parts? ( AP4290980, AP2996314). Thanks in advance for your insights.

My dryer has been having trouble tumbling. When the dryer starts, the drum will turn 3/4 way and then almost come to a complete stop, then repeat that motion. As first I thought the belt might have slipped into one of the grooves on the drum, that however was not the case. Under normal operation, does the idler pulley itself turn freely, or is it fixed in a certain position? If indeed the pulley has to move, then I can say that the pulley in my dryer has seized up. The idler pulley on the dryer is a little odd in its design. Instead of having a complete circle groove around, the pulley has a angled cutout that only goes around a bit less than half way around. The rest of the pulley is flush with no groove. Here is what I think is happening. After I repositioned the belt back into its proper alignment on the drum. I believe the idler pulley is causing excessive rubbing on the belt (hence it being seized up) thus causing the sudden rotation slowdowns. Will replacing the idler pulley be sufficient enough? Or will the idler arm with washers and c-clamp also need to be replaced? Thanks.

Latest Questions

I have a neptune dryer that has just started to vibrate consistantlywhen the dryer is running. I took off the front panel and the noise occurs when I hand turn the drum but only in thecounter clockwise direction. I looked at the rollers and they spin freely and don't feel loose. The noise stops when the belt is removed. Is this a tensioner pulley or belt issue?

Hi, Belt broke so I got a tune-up kit, also a vent system kit. Well, there's this clear round plastic piece that melted too. It was off on its own & I'm thinking this is the belt tension item, is it?

My dryer was squealing and chirpping while running. I've replaced the two drum wheels and support glides and the noise still exists. Could it have just been the idler pulley or belt? It seems to be operating properly other than the loud noises.
