I bought a used Precor 9.4 treadmill, but the incline adjustment was not working.
So, I did the following.
1. Turn off, unplug the treadmill and wait for an hour (this is for safety
2. Remove the black motor cover
3. Observe the transformer to the right of the motor and towards the belt ( I point to it in the video)
This transformer converts DC electricity to AC electricity and the AC current goes directly to the Incline motor which is in the black box towards the front of the machine.
4. On mine the wires had come loose from the transformer, they were soldered on very poorly, the wires are stiff and you should be able to see 4 wires coming from the top of the circuit board and plugging into the transformer, I had three of the 4 wires loose.
5. If you are not comfortable working with electronics or soldering DO NOT DO THIS REPAIR, you could get shocked very badly if you just go poking around in there with metal objects, get a friend who knows how to solder or hire someone.
6. It took about 5 minutes I just heated up my $10 soldering gun from radio shack and soldered all the loose wires that were about a millimeter away from the tabs on the back of the transformer, and VOILA! The incline now works!

Because you are hearing the lift motor making a noise, it sounds like the gears in the motor are bad. The fix is to replace the lift motor.

You probably need a technician to look at it. I would say the motor that runs the treadmill is faulty due to a fuse that has blown you would have to locate where this is first replace it and proceed to the nxt step. I say you may need a technician cos often you are dealing with mains power or small dc voltage in any case one should carry this out in a safe way.If you are not confident ring a professional Tech.
