Maybe the control board is fried? Is your machine plugged into a surge protector? If not, a power surge could have fried the computer on it. Does anything else work on the control panel?

SOURCE: treadmill motor cuts out on speeds 10km/hr or more

Sounds like you've never lubricated the belt. This has caused frequent overheating issues so now at higher speeds, the motor control board overheats and shuts down.

You'll have to first loosen the belt, then lubricate it. After words, tighten the belt again, if at all possible, don't tighten it as much as it was before, as overtightened belts are often a contributing factor.

Then calibrate the treadmill, make sure you are using a surge supressor and you hould be good for a while.

SOURCE: Treadmill incline error

Try this, it fixed it for me, if it doesn't work let me know
http://www.youtube.com/watch?v=MIIxoPtvhy8

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.

SOURCE: my tunturi treadmill 661f is showing E1 on the

E1 error code : Unplug unit remove motor shroud and check the distance between the speed sensor and the flywheel and ensure that the speed sensor is properly attached to the motor frame. Check also speed sensor connections.
Unplug the electrical cord from the wall outlet and from the treadmill, wait 1 minute and turn the power switch on again. If treadmill recovers to normal operation, you may continue to use the treadmill.
Check the motor brushes either they worn or not sitting properly

SOURCE: The incline on my proform treadmill is not working

ICON CALIBRATION INSTRUCTIONS- INCLINE
1) Press the Stop and the Speed Up keys down while inserting the safety key.
2) Press the Stop key one time. The Time window should read EP:2P. Some newer models may also say FP, Pass, or the like. This means that it passes the EPROM test.
3) Press either incline key and the incline will calibrate automatically.
4) THIS IS A VERY IMPORTANT STEP BECAUSE YOU WILL GET AN ERROR MESSAGE IF THIS STEP IS SKIPPED.After completing calibration of incline, press the Stop key and then remove the safety key.



If the incline moves but you it will not operate normally nor calibrate, check the wiring from the incline sensor to the power board. If all looks normal, put it back in calibration and see if you see a blinking “- -” symbol in the incline window when you are calibrating. If not, the incline sensor is bad.

If the incline moves but only just a bit, it could be a problem as simple as the gearbox on the motor being jammed. We remove the motor from the treadmill, reconnect the wiring, and then try to run the incline motor outside the treadmill. Many times, this will unjam it if that is the problem and then reinstalling it in the treadmill will get it to work. If you have the same problem or it doesn’t run outside the machine and you can hear it try to work, you need to replace the incline motor.

If the incline motor does not move, we need to figure out if the motor is getting voltage. Use a simple multi-meter and set it to AC volts. When you put it into calibration, it tries to calibrate the directions one at a time. Measure across the white and black wires first, then measure across the white and red wires second. If the motor is getting voltage you will read 120VAC (or
thereabouts) one one of the measurements. If you have voltage but the motor won't move, you need to replace the motor.
4.
If the incline motor does not move and you have done the voltage test and you do not have any voltage present, there is a problem in the electronics board that supplies the power. If the console is powering the drive motor as normal, you can bet it is getting an incline signal and the power board needs to be replaced (some models have an integrated power board/controller) so if there is only a single board the whole board has to be replaced. It is possible the console is not giving the proper signal but we've never seen it happen in thousands of treadmills.

How to reset/recalibrate your treadmill after replacing drive or incline motor,...

Make sure you recalibrate your treadmill after installing ANY controller, motor or console. You can NOT over calibrate your treadmill. You want to make sure you adjust your pedometer for the correct operating speed and incline adjustment. First plug in your treadmill, do not stand on the walking belt. Hold down the "Stop" and "Speed +" key and insert the safety key or magnet, let go of the two keys. Now press "Stop" key once. This puts you into the level 2 of calibration. Press the "Speed +" key slowly until you see 85 on the console, (at this point the display is going to show the percentage of motor usage and also the actual walking belt speed) at 85% motor usage your top speed should be between 10 and 10.5 MPH or (of 12 and 12.5) depending on the treadmill. You must know your treadmills top speed. (Important the motor may be damaged if you set the maximum speed higher than the maximum speed that your treadmill is made for). If the speed is higher than 10.5 or 12.5 then you need to turn the potentiometer down to the correct level. The adjustment is made with a phillips screwdriver, and the adjustment point is on the motor controller. It is a little square metal box with a yellow plastic adjustment screw inside. If the speed it to low you need to turn the potentiometer higher. Once the speed is correct you are done calibrating the speed. Press the (-) speed key to lower the percentage to (0). Next press the incline (+) button, this will make the incline motor go all the way to the maximum incline and come all the way down to the level position. Then remove the safety key and the treadmill will reset into the normal manual mode. Double check that the treadmill is operating at the correct speed and incline motor works correctly, by running maximum settings. Once you are done, be sure your treadmill is properly protected from surges from power spikes that can destroy the work you just performed.

Hope this helped.

The incline on our Precor c964i is stuck in a high position (approx. 10% incline). Other than being on a high incline, the treadmill seems to be working fine.

Hi There,

Precor uses a pair of Triacs to drive the lift up and down. These triacs live on the lower board but are driven by the upper console commands via a serial link between the upper and lower. Most precor lift issues we see are related to the lower board but with Precor it could be an upper board or the CPU Chip that resides on the lower board or a failed Triac. Good Luck

Lower incline

Dear Sir:

I STRONG recommend RUN the calibration Software Inmediately, for eay Diagnose and troubleshooting, most of them instruction has coming in the Hood of Motor, follow the instruction or use your instruction manual.

Adjust the sensor speed attached the diagram. Tight the wires from sensor speed. The sensor speed can be faulty. Adjust the Pot with the gear in the same motor, both can be faulty. And finally the main motor board can be wrong. sincerely.

God bless you.

Every time I put the key in my Proform 590T, the incline rises for a second, and lowers for a second while displaying 2 hash marks. Then, the home screen comes. All speeds work fine for walking/running,...

how long have you had this treadmill? usually when the hash marks appear it means that the console control board is not recognizing the incline motor. even though it does run a little bit that is just the basic test that the treadmill starts but resets after it does not sense the incline motor. These motors rarely go bad so it is more than likely your motor controller that is causing the issue. I have seen this case many times as i am a fitness repair technician. The motor controller fixes the issue 9 times out of 10

My console does not allow me to change the incline, speed, etc. The control panel does not acknowledge the buttons pushed. I've turned it off and on.

my treadmill is doing the same thing. the only buttons that work are the start; incline up. 4 incline; 8 incline; and 11 incline.
