Dryer with loud rumbling noise every 20 to 40 seconds, lasting 5 sec
Hi,
ANSWERS:
"Cause 1
Drive Belt
The drive belt is a very long, slender belt that wraps all the way around the dryer drum, around a tension pulley, and then around the drive motor. Over time, the drive belt can become frayed or otherwise damaged. If the drive belt is frayed or damaged, the dryer will be noisy as it turns. Inspect the drive belt for signs of wear. If the drive belt is worn, replace it.
Cause 2
Drum Roller
One or more of the drum rollers might be worn out. Many dryers have two drum support rollers on the rear of the drum, and some dryers have two more rollers supporting the front of the drum. When the drum rollers are worn out, they can cause the dryer to make a loud rumbling noise. To determine if the rollers are worn out, inspect the rollers. If one or more of the rollers are severely worn, we recommend replacing all of the rollers at the same time as a preventative measure. (The roller shaft can often be reused if it is in good condition. Clean the shaft thoroughly before installing the new rollers.)
Cause 3
Drum Roller Axle
One or more of the drum roller axles might be worn out. Most dryers have two drum support rollers on the rear of the drum, and some dryers have two more rollers supporting the front of the drum. Over time, the drum rollers and axles wear out, causing the dryer to make a loud rumbling noise. To determine if the drum roller axles are worn out, remove the belt from the dryer and try turning the drum by hand. If the drum does not rotate freely, check the support rollers for wear. If the rollers spin freely without wobbling, the axles do not need to be replaced. If a roller wobbles and/or does not spin freely, we recommend replacing all of the axles and rollers as a preventative measure."
Gee, I just wish that my problems were as easily fixed, my Maytag heavy duty dryer is only 5 months old and it’s making a loud knocking noise every time the drum turns, I use it several times a week, I called Maytag and they said that it happens when the dryer is not used very much, but I have six kids, mine gets used a lot. But they never really could answer my question about why it’s doing Pithecanthropus knocking. The said they were going to send a technician out, but they have called twice and rescheduled the appointment. So, I’m just not sure what they will do.
