Our Nordictrack T 4.0 is making a new noise as the belt goes around and the machine now vibrates / shakes in a way it wasn't before. What's causing this and what can we do to remedy it?

It very well could be the strut.
smaller chance could be the CV axle.
Also have the splash guards/heat shields checked to make sure they are all tight in place.

Hi,Whynter Portable Air Conditioner has many moving parts, and they all make noise and cause vibrations. Some of these parts are more likely to causing shaking and loud noises, and sometimes this signals a larger problem, something to watch and scrutinize. If serious enough, it calls for a repair.

Loose Parts

Loose parts cause the majority of shaking and vibration noises in your air conditioner. A few of the most common loose parts include the air compressor, the piston rods and even the fan or blower unit itself. These noises are clunking, clanking sounds that occur along with a vibrating action. The only method of repair is a complete compressor replacement, which is a repair only a certified air conditioner technician is qualified to make. The compressor is a fully sealed component, so individual parts in the compressor cannot be repaired.

Fan Blades

Fan blades cause noise, shaking and vibrations even when properly secured. If fan blades contact the exterior structure of the air conditioner due to a bent fan blade or broken and misaligned grate, a constant, repetitive noise and vibration results, which sounds like a ticking or banging from the interior of the air conditioner. Vibration in this case is limited but still present.

Mounting Brackets

When an air conditioner shakes, there is a problem with the mounting brackets. These brackets hold the air conditioner compressor steady as it operates. Normal vibrations and shaking would otherwise occur without these brackets. A loose mounting bracket causes the air conditioner to rock back and forth and creates a clanking sound. As the compressor starts up, this rocking and clanking sound begins, resulting in a very loud and fast vibration and noise. It also occurs when the unit shuts down.

Other Sounds and Vibrations

Sometimes air conditioners squeal, hiss, hum or screech. Each noise is often accompanied by a vibration. Humming sounds along with a vibration may indicate a bad capacitor, the electrical part responsible for starting the machine. Hissing sounds tend to indicate a pressure problem while screeching and squealing sounds are fairly common in window air conditioners and in central air conditioners. This sound is also a result of the compressor motor. It usually starts when the unit turns on and continues through its normal operating cycle. Vibrations always occur in the air conditioner due to moving parts and the compressor motor's operation.


Hope it helped..

Sounds like either the unit was secured to the wall again, or that the belt wasn't put on tight enough causing the fan to move around and make noise.

Hi,

When my washer did that, I found that the shocks that hold the tub were bad...

Check out this tip I wrote about the noise and vibration that front load washers can make..

The spindles on the deck may need replacing.Thanks for asking and I hope this helps out.Please leave me 4 thumbs up.

Could be a broker motor retainer. There should be two motor retainers in this model, when one is borken, it causes the unit to
shake and vibrate.

has the machine been knocked recently?if so,the belt may have come off,or the drum could be out of allignment.

most common cause for this is pump bearing on water pump. remove belt and attempt to turn pump by hand. if it grinds get a new pump.

Spin Shake is usually contributed to a weak floor support condition. Also, carpeting under the leveling legs can cause a "spongey" effect, which can produce the shakes. Prolonged shaking can cause parts to loosen and make noise.Firstly, we must determine what loosened up from all the shaking.

Remove the front panel by removing the 2-5/16" screws located at the bottom front. Pull out at the bottom to release the top retainer clips, and set aside.
Warning! Never reach inside the machine while it is in operation!
Investigate the cause of the noise by setting the washer to spin, and turn on. Inspect all moving parts for possible wear or breakage. Next, stop the machine and inspect for loose or worn suspension parts, nuts, bolts, struts, hoses banging the cabinet, etc. A protective motor cover can cause noise, or a belt slapping the base mount. Once you have conquered your noise issue, then we will have to eliminate the shakes, provided, what you repaired wasn't the cause...and usually isn't.

Carpeting under the leveling legs should be removed or cut away.
If other items in and around the laundry room shake, then you will need to add support to your floor joists. Shim the floor from under the house while the washer is spinning for best results.

Your installation instruction manual should tell how level the washer properly, after you have added support to your floor.

Good Luck! Post me back if can be of more assistance.
