I have a proform treadmill that makes a high pitch whirling noise that get louder the faster it goes. Sounds like it is coming from the motor, not the bearings. Suggestions?

indicates wind turbulence noise
possible around rear view mirrors , weather shields , door edge , bonnet edge , headlights
trial and error is to place tape over adjoining edges to see where a placed tape stops the noise

Have the accessory drive belt checked and the automatic tensioner for that belt.

The roller is not difficult to replace, it is also no really expensive.
Part number is #219035 it is around $80 from the manufacturer.
The phone number to order the part will be found on the model/serial number tag on your treadmill.
When folded, there is a tag on the frame of the treadmill with a correct model and serial number and the 1-800......

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

bad bearing in the front roller

If the noise is coming from the walking belt this could be due to sand or grit getting under it. These belts are big electro-magnetic generators. The attract sand and grit to them. Usually it will make a high pitched sound when there is sand under the belt, especially if there is a mylar or plastic sheet under it. If this is the case the sheet can easily be replaced.

This definitely sounds like the drive motor. One way to check is to remove the drive belt and run the motor without the walk belt connected. Obviously if you still have the noise it will be a motor issue. If not then it will be one of the 2 rollers. Good Luck! Tim

It sounds like the belt is slack there should be an adjustment at the rear of the belt at either side of the treadmill usually a hex stud or allen key, if that doesn't help check the drive belt that comes directly from the motor which could also be slack or damaged.

Bearing in the motor are bad. Replace your motor.

Sounds like fuel pump pressurizing the fuel system. They do that for 2-3 seconds and then it stops (for fuel injected vehicles).
