Question about Proform 980 CS Treadmill
When I turn on my pro-form 980 if I press any button the speed goes to 12 and it won't slow down, the stop button doesn't work, I have to pull the red button off.
1) test the speed sensor, for open or faulty, see the adjustment. Clean if and tight the connector very well
2) tight the ribbon cable for keypads , and clean it
3) replace batteries,and clean the contacts baterries very well
4) adjust the Reed swtich, test for open or faulty, clean it and tigh the connector very well see the diagram
5) Run the software calibration for troubleshooting, diagnose, and fix it.
God bless you

I know this thread is a little old, but did you get your treadmill working? I have a 550e that does the same thing. The company has sent me 2 controller boards, but still doesn't work.

If you have not ever lubricated the running deck then I suggest doing so . What happens is that the lack of lubrication will tend to make the belt drag thus slowing down the belt making the motor control board to try to compensate the drag.

It is trying to its starting point I would suggest is to unplug the unit open the motor shroud unit. The shroud it has a mini manual this should have a calibration instructions that can be done and also upper electronics self test to see if the processor is functioning properly. It should give a better idea which to head. You can call Icon Fitness@ 1-800999-3756

Press the Stop and the Speed Up keys down while inserting the safety key. This should get you into calibration mode. 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. If you cannot get into calibration or if the EPROM test fails then the upper console will have to be replaced.
If you get pass to this point then proceed with the calibrating the incline and speed.
Press either incline key and the incline will calibrate automatically.
Be careful the treadmill will run at full speed in the next mode DO NOT STAND ON THE WALKING BELT.Press the Speed Up key and hold it down until 85 is shown in the Distance window (some models may show the 85 number in another window).
If the top speed of the treadmill does not match the displayed speed on the computer console, adjust the max speed potentiometer (pot) on the motor control board. This is the board that the red and black motor wires connect directly into in the motor area. The Max Speed pot is clearly labeled
The max speed potentiometer is a small square with a mobile center and is located in one corner of the board and is labeled MAX SPD. It is near the harness that carries the speed signal labeled H,W,L. Using a small insulated screwdriver adjust this potentiometer clockwise to speed up and counter-clockwise to slow down the max speed of the treadmill. A tiny turn of this potentiometer will make a big difference in speed so be careful when making adjustments.
It is not important to get the speed set exactly at the max speed of the treadmill but do make sure to get the speed within .2 MPH of the max speed of the treadmill. For instance if the max speed of the treadmill is 10 MPH, make sure to have the speed set between 9.8 MPH and 10.2 MPH. Some models have a 12 MPH top speed, so please check your manual if you aren’t sure.
After completing calibration of the speed, press the Speed Down key. The treadmill will automatically return to 0 MPH. Please allow the unit to stop completely before continuing. Press the Stop key once and remove the safety key.
