Possibly fuel pump.

There are a few potential remedies for a humming motor on a Proform 395e elliptical:

1. Tighten any loose parts: If the humming noise is coming from the motor, it could be caused by loose parts that are vibrating against each other. Try tightening any screws or bolts that may be causing the noise.
2. Check the belt: The belt that connects the motor to the elliptical's flywheel may be loose or damaged, which can cause a humming noise. Tighten the belt or replace it if it is damaged.
3. Check the flywheel: If the flywheel is damaged or out of balance, it can cause the motor to vibrate and make a humming noise. Check the flywheel for damage and replace it if necessary.
4. Check the motor bearings: If the motor bearings are worn or damaged, they can cause the motor to vibrate and make a humming noise. Check the motor bearings and replace them if necessary.

If you are unable to identify the source of the humming noise or fix it yourself, it is recommended that you contact Proform customer service or a qualified technician for assistance.

No a noise filter is a different kettle of fish. That stops electrical interference noise from affecting your television, radios and electrical devices.

The most likely source of the hum is the start capacitor on the motor, or the motor itself.

Hello. I want to know more first, does it only make noise in motion or all the time?

power steering pump make humming noise and alternator with bad shaft bearing make noise.

check your audio line in connection, either L or R signal line floating may also cause humming noise. Sub woofer usually very sensitive. If your audio input not connected, do you still hear humming noise? in actual you should not hear such noise, unless volume at max then it is possible to hear little.

The montherboard doesn't have anything that would make a humming noise. In all likelyhood it's the fan that sits on top of teh processor. It could be normal, but might need to be replaced or cleaned.

Replace the fan motor. Sounds like bearings are going bad.
