Clothes dryer makes a ''thumping'' sound

what's the brand name and model number?when it spins if you hear a thump thump as it spins that could just be the drum where the rollers hit it,i've heard that alot of times in dryers,i wouldn't worry about it,if it heats and spins and it doesn't sound like metal on metal or not making a real loud noise it's most likely just the drum,could be a little out of round and when the rollers ride on it you hear thump thump then when it spins you hear it again it will be fine,look at the drum,you might see some black stuff on it where the rollers ride on it,you can try cleaning it up it might help but i wouldn't worry about it.

BAD ROLLERS OR BAD TENSIONER SPRING

Sounds like the tub is unbalanced from either a bearing/pulley suspension problem or the unit has broken something off in between the tub and outer portion of the unit before you get to the walled panels, and you are hearing a rubbing and thumping noise. This is not a typical DIY job since the entire back panel of the unit needs to be pulled off and diagnosed.

It sounds like you're lacking air flow. I'm sure you're cleaning the lint trap / filter - but have you clean the VENT HOSE / PIPE?

The 4 in vent hose is supposed to be cleaned annually. If you have the flexible vinyl hose, replace it with either steel, aluminum or flexible aluminum tubing instead. Once you've removed the vinyl hose, it will collect a lot less dust and can be cleaned without worry of puncture.


A typical dryer vent brush.

Make sure there's no obstruction to the flap outside, too. Once cleaned the dryer operation should be restored to new again.

I hope this helps & good luck! Please rate my reply - thank you.

Hi,

Here is a tip that I wrote about dryers and noises...

It will help you determine what is happening there...

Dryer Repair Squeaks, Grinding, Clicking and Knocking Noise

Asker

The belt tensioner roller has a flat spot caused by a worn bearing that catches and stops whilet the drum is turning. This causes the flat spot and the noise its making. You can purchase a new roller by itself and do change the belt the same time too

usually when this happens it's from the felt seals that are on the drum,the clothes are passing through the seal and hitting the rollers,as for other problems if the timer is bad the seals and you have a noise problem,you might just want to get a new dryer,nobody can help you without the model number and if you're gonna try to fix this you'll have to send alot more info than what you sent

If your clothes get stuck, marked or torn in your dryer, check these:

Rollers
Rear seal
Front glides
Front seal
Rollers Your dryer may use rollers, or wheels, to support the rear of the clothes drum. When these are worn out, they may cause the clothes drum to drop down slightly, which can pinch the clothes between the top of the clothes drum and the rear of the dryer interior. When the rollers wear out, you need to replace the whole set.

Rear seal Your dryer may have a felt-like seal at the rear of the drum. If this seal is worn, torn, or missing, clothes can get caught and torn in the space between the clothes drum and the rear of the dryer interior. When the rear seal wears out, you need to replace it.

Front glides Your dryer probably uses nylon or plastic glides at the front of the clothes drum for support. When these are worn out, they may cause the clothes drum to drop down slightly, which can pinch the clothes between the top of the clothes drum and the front of the dryer interior. When the glides wear out, you need to replace them as a set.

Front seal Many dryers have a felt-like seal at the front of the drum. If this seal is worn, torn, or missing, the clothes in the dryer may get caught and torn in the space between the clothes drum and the front of the dryer interior. When the seal wears out, you need to replace it.

UNEVEN LOAD

Take off the back panel of the dryer and look at the motor and belt turning the drum. There may be something caught on the drum and is pinned in place causing the noise. The motor could be loose on the platform and needs to be tightened. It is probably something physical and seen causing the noise.
