Question about Precor C956i Treadmills with HR / WholeSale

Noisy precor treadmill motor

When I turn the unit on, there is a very loud guttural sound coming from the motor which never goes away. 9/10 on a 1/10 scala.Also, a faint tinny sound is detected from inside the motor. At low speed, the motor occasionally changes speed with no apparent reason.

    We have a couple Precor 954i treadmills that hav ethe same noise problem with the motor. I called Precor and they said the replacement motor is the same as the orginal. I do not want to buy the same motor if it is going to have the same problem a couple years down the road.
    I would prefer to fix the motors if possible. I asked a couple service tech guys in my area and they say it is very hard to get the bearings out of the motor and to put back in.
    Any advice on how to repair the motors is appreciated.

How Loud Can it Go?


I don't know if I ever installed a sound system to any concert fan who didn't ask me this question. So how loud can I safely play my sound system?

If you have a receiver or amplifier that has an analog dial that goes from 7 o'clock to 5 o'clock the majority of units will output maximum volume at around 1 o'clock assuming a line level signal is sent to it (again it varies a lot from piece to piece). Anything higher then that and the unit will send out a distorted signal colloquially referred to as "clipping". Most modern units now use digital volume controls and everyone is different. The only way to detect this distortion is listen to when the music sounds tinny and harsh instead of clean and musical.

If you do not find it is loud enough for your liking you must invest in a more powerful amplifier or higher efficiency speakers; or you will continue to destroy your innocent speakers and blame them for your over driven amplifier.

One HDMI input creates a sound problem - only faint and tinny sound.


Unless the jack is physically damaged, then the entire digital pcb would need to be replaced. Sometimes just the jack can be replaced, but that is a pretty tricky repair.

The sound is the heater getting air in it from air in the cooling system. Have the system pressure tested for leaks.

Faint to loud humming noise while driving and turning...


Could be either a loose belt or you are low on power steering fluid,or the power steering pump could just be worn out.

Outside fan does not spin and a loud screeching sound coming from


Hey there, sounds like the bearings seized in your fan motor. You need to replace the fan motor. If the compressor runs without the fan, th pressures build up and if they reach an extreme point, the compressor will bypass internally, creating a loud sound as the high pressure is released to the low pressure side. I would turn the thermostat on and stand by the outdoor unit as it start. Leave the disconnect on the wall readily available so you can quickly turn it off. If the compressor sounds ok when it starts up and runs for a couple seconds, turn it off right away and replace the fan motor and you should be good to go. If the compressor sounds bad or real noisy immediately at start up, the fan motor not working killed your compreesor. You would need a motor and compressor, might as well replace the unit at this point if you are paying to have it done. Let me know if you need anything else
