We have a Nordictack A2350 treadmill and it has a load ticking noise in the motor ? The motor runs fine but the noise is getting louder ?

Be sure to verify if you are getting the noise while you are physically on the machine or with no one on it
Creaking or squeaking while running on the machine usually indicates an issue in your incline motor, deck frame, springs, and or pivot points

A loud grumbling noise getting louder and louder while elevating speed, usually means you have a bad bearing

Any knocking noise coming from a treadmill indicates bad bearings in your front roller, rear roller, or drive motor

Isolate the bearings in the front and rear rollers from the drive motor bearings

To test: Unplug machine, remove the main shroud, remove drive belt from drive motor and front roller pulley

After doing so, move the treadmill belt by itself by pushing it backward or forward with just your hands and listen for any noise, if you get any noise it is most likely coming from either the front or rear roller. To isolate the noise out of the two rollers you must remove the rollers and turn each one individually.

If no noise with the first test, go ahead and start the machine and run it at a low speed. You want to listen for noise, if you get knocking or grumbling while drive motor is running with no drive belt attached then the issue is in your Drive Motor.

A lot of times simple maintenance will save your treadmill from noise, you want to make sure and lubricate your treadmills *pivot points. Incline motor bolt, shaft, deck screws, and or any *pivot points on the bottom of your machine. Metal on metal *pivot points are usually the culprit in most cases.

*Pivot points are just areas of high friction where there may be a bolt, washer, and nut attached to the base of your frame or any hinges on your folding type treadmills. Metal to metal needs to be lubricated to minimize wear and tear of those areas.

Synthetic grease works best or any spray on lubrication works fine if you do not want to remove any bolts or hardware.

Try to open and separate the motor carefully from treadmill chasis, turn the motor shaft with hand if it not easily turn or you hear a unsual sound try to open the motor and add a lubricant to motor bearing, and turn the motor on if its still noise replace all the bearings with new one

Check the front roller. Remove the drive belt and run the motor. If the noise is not there replace front roller.

plealse LUBE the deck belt + rollers bearing too . you must do it after 150 miles aprox.
2) adjust the REED switch see the diagram, clean it, test for open or faulty. Tight the connector very well.
God bless you

see the video and proceed according.
God bless you

the ticking , if you hear it on the top of the motor, will be a rocker arm,, it could be plugged and not getting oil, if its coming from lower down in the motor, it is possibly a stuck valve,, or a rod bearing , if its a ticking noise its more than likely the rocker assembly,, if its more of a knocking noise its lower in the motor

Hi,

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.

The replacement motor is around $200.00.

Hope this helps

Could be a number of reasons - where is the black dust coming from? remove the motor hood and check for misalignment of the drive belt from motor to the front roller.

Bearing in the motor are bad. Replace your motor.
