Drum drive/motor growling, also very brief repeated hesitation audible
During drum rotation drive/motor noise significantly louder than usual producing a deep consistent growling sound. Sound is similar to "normal" operation, only significantly louder.
Another symptom might occur several times a minute. Audible hesitation in drive motor with each hesitation lasting only a fraction of a second. This is not the,much longer, normal hesitation of stopping and restarting drum rotation.
This 3 to 4 year old machine still drys OK, but I am concerned that a failure is lurking somewhere inside.
Thanks for your help! Dale

Re: drum drive/motor growling, also very brief repeated...
Dale you are correct, the dryer has a part starting to fail. If you remove the top and shift the cabinet the noise may increase or decrease. If this happens, then the rear panel is bent in that supports the rear bushing. You can replace that to resolve this. If the noise doesn't change, I suggest you check the blower, Sometimes the blower will spin freely on the motor shaft and cause a noise. Since this blower wheel also cools the motor, it could be spinning. Try removing the blower and add a washer behind it to tighten it to the motor shaft. This is just a press fit blower wheel. If that doesn't resolve the issue, then replace the blower wheel. Hope this helps.

check tires as well. But yea if you are driving when the noise exists, swaying back and forth in lanes will let you know if its a hub noise. If its a hub noise the growl will be louder or different when weight shifts off and on the hub. Where weight is on the hub it usually gets louder. Alot of the time there may be two problems like tires and hub noise. Tire noise is easier as rotating front wheels and rear wheels will change position of growling/howling noises.
That could be the motor roller or drum rollers gone. You need to take off the front top to access inside. Take off the top first, then remove the control panel, then the front. You may need service person to help.
Grinding noise, growling noise, thumping noise? Something else?
If it's a grinding noise, more than likely it is during stops. In this case it is probably metal on metal in the brake pads.
If it is a growling it can be in the wheel bearing or CV shaft which usually gets louder with turning or banking.
Is it is a thumping can be from a tire issue, a strut, a sway bar link banging around etc.
Need to clarify the noise and how you are hearing it.
It sounds like you have a drive motoer failing. The only other place that can be load or making noise is the front and rear roller. The rollers bearings when failing make a "popping" or "clicking" noise, and increases as you speen up. The motor "growls", and the faster you go the noise is..... well loud. The way to confirm this is to remove the motor hood, then start the treadmill on power/speed level 3. Be very carefull, and use a broom stick (wooden) to put on the drive motor while it is running. You should be able to "feel" what you are hearing. You should then raise the speed, and you will then feel the increase as well.
Describe the noise. If its a rattling banging noise you could have a broken exhaust fan which is usually attached to the motor, a broken cylinder roller (if your dryer has them) or worn felts. Maybe a noisy pulley. If its more a high pitched squeek it could be your motor or the parts just mentioned. A metal scraping noise could be something like a bra wire caught by the cylinder but I don't see how that can get louder as the rotates. Make sure the belt isn't cracked all over. Worst case scenario is that your motor is on its way out...
WHEEL BEARING USUALLY STARTS MAKING A ROARING TYPE NOISE WHICH USUALLY GETS LOUDER THE FASTER YOU DRIVE, SOMETIMES THEY WILL BE LOOSE , TO CHECK JACK UP THAT WHEEL AND GRAB TOP AND BOTTOM OF TIRE AND SHAKE, IF THERE IS MOVEMENT, TRY TO GET SOMEONE TO ROCK TIRE FOR YPU AND WATCH WHERE AXLE GOES INTO CENTER OF BEARING AND SEE IF AXLE IS MOVING WITH TIRE MOVEMENT AND SPINDLE REMAINS STATIONARY, THEN IT IS BAD BEARING, OR SOMETIMES THERE WILL BE NO MOVEMENT, THEN BLOCK REAR WHEELS AND RUN CAR WITH THAT WHEEL IN AIR AND SEE IF YOU HEAR NOISE, GOOD LUCK.
hi from the symptoms you calearly describe may i suggest that b4 you drive vehicle any further you must 1st raise and support the wheel you mention that gets hot ? make sure you chock front wheels then release park brake now check suspect wheel by rotating it to see/feel/hear ? any undue noise or stiffness most of all try rocking wheeltop to bottom i am suggesting you problem may well be the wheel bearing is shot and the heat is due to eithe the bearing run dry thus allowing the brake drum to tilt and resulting in brakeshoes to contact and cause friction /overheating of drum and transferring to actual wheel rim hope you understand above ?
Hi Charlie, These machines have a history of growling, however usually they growl before changing the fuser. The fuser is most likely the problem maybe you got a bad one. If you still have the old one and it was quiet you could pop it back in to confirm. Ther is also a gear kit available to replace the fuser drive gears but usually the noise is in the fuser.
Another growling noise can come from optional tray3 if installed. Easy to diagnose just lift machine off the assm. and print.
