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.
Answer Hello Paul,
The idler pulley (AP4373393) should in no way be stationary. If it is seized, you should probably replace the belt (AP4043963) and both drum rollers (AP4008534), (two of these), at the same time since they tend to fail within 3 months or so of each other. Be sure to clean the sticky residue off of the roller shafts for both the idler pulley and the drum rollers with rubbing alcohol and paper towels. If flat spots are worn on the drum roller shafts you can loosen the 1/2 inch nut on the back of them and rotate them to a position that is round and they will not have to be replaced yet. Be careful doing this since they can be tight and you can get a nasty cut when they break loose. WEAR GLOVES! The idler arm will not need to be replaced unless a flat spot is worn on it also.
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.
Answer Hello Todd,
This sounds like the idler pulley 6-3700340 since the other parts you have changed pretty much cover the other causes of the complaint. The belt 33002535 is what makes the noise, but it's because it's slipping over the part that is opposing rotation. As long as the belt looks good all of the way around, it shouldn't need replacement unless you just want a new one in while it's apart.
Is the pulley supposed to have a hole or space in it?
Answer hello Claudia. The pulley 6-3700340 should have a hole for the shaft to go into. Hope this helps.
My dryer is squealing at start up. Is this a sign that it is the tension pulley or the belt that needs replaced? Is it that the pulley can be adjusted?
Answer Hello David. You will need to remove the belt from the pulley 6-3700340 and see if it is bad. Turn the pulley by hand and see if the pulley drags on the shaft. Do not run the dryer before checking the pulley. if the pulley is tight on the shaft, you will need to replace the pulley. There is no way to adjust the tension on the belt. Hope this helps.
