Key board will not respond to inputs. incline, speed and more

It appears that there may be an issue with the speed and incline controls on your used Sole F85 treadmill. Based on the information provided, here are a few troubleshooting steps you can try:
1. Check the control panel connections: Ensure that all the cables and connectors between the control panel and the motor control board are securely plugged in. Loose or faulty connections could cause issues with the speed and incline controls.
2. Inspect the control panel buttons: Examine the buttons on the control panel to see if any are stuck or not functioning properly. Sometimes, debris or dirt can accumulate beneath the buttons, preventing them from working correctly. Gently clean the buttons and the surrounding area to remove any obstructions.
3. Test the speed and incline motors: The issue could be related to the motors responsible for adjusting the speed and incline. Test the motors individually by manually applying power to them while disconnected from the control panel. Observe if they respond correctly to the input. If the motors do not respond as expected, they may need to be replaced.
4. Examine the motor control board: Inspect the motor control board for any signs of damage, such as burnt components or loose connections. If you notice any issues, it may be necessary to replace the motor control board.
5. Seek professional assistance: If the above steps do not resolve the issue, it is advisable to contact a professional technician with experience in treadmill repairs. They will have the expertise and specialized equipment to diagnose the problem accurately and recommend the appropriate course of action.
Since your treadmill is a used model and the control issue has persisted for some time, it is possible that the problem is more complex and requires professional attention. A technician will be able to provide you with a more precise diagnosis and help you determine the best solution to get your Sole F85 treadmill functioning properly again.
Remember to prioritize your safety when dealing with electrical equipment, and always disconnect the power source before attempting any repairs or inspections.

you need to replace the key pad

I’m happy to assist further over the phone at https://www.6ya.com/expert/james_1cb31da1bc8c6102

1) Lube the deck belt, maybe you have a worn deck belt, use 100% silicones or wax, check your instr. manual
2) Lube the rollers bearing with wd-40 very well
3) Test the drive belt motor, for cracking or worn belt
4) Test the input voltage motor, if there are the motor need repair, please go to my personal TIPS for motor help
5) Test the output voltage board, for input voltage motor, if there are NOT the board is faulty, see the block dia
God bless you

.5 oz of Icon lubricant(can be purchased on ebay cheapest) applied to deck. Adjust the walkbelt, check drive belt tension, check amperage on motor no load and under load, calibrate the speed and incline. You can calibrate your treadmill by doing the following:
let's try to calibrate the speed

1. With the key off press the speed + and stop buttons at the same time and hold
2. place the key on and release the buttons
3. press the stop key once
4. press the speed up til it reaches 85
5. if your max speed is 10 mph then it should read about 9.8-10.2
6. If it is over or under we will need to adjust the speed potentiometer on the motor controller
7. to do this remove the motor hood and find the electronic board.
8. there will be a round adjustable pot on the board that you can place a small screwdriver in to adjust.
9. depending on if you need it to speed up or slow down is the direction you will need to turn it.
10. the goal is to get it to be about .1-.2 mph more then the max speed of the treadmill.
11. As long as it is in the range above it is performing ok.

now to calibrate the incline:
1. remove safety key
2. press and hold the speed+ and stop keys at the same time
3. Put the safety key in/on and release the keys
4. press stop once
5. hit the incline + arrow and let the incline go the whole way up and down

Remove the console from the treadmill and remove the back
remove and replace the ribbon cables that run from the keypads to the control board (they are flat plastic strips that push into the board).
remove and replace all the connections on the console
reattach the console and calibrate by doing the following:
1. With the key off press the speed + and stop buttons at the same time and hold
2. place the key on and release the buttons
3. press the stop key once
4. press the speed up til it reaches 85
5. if your max speed is 10 mph then it should read about 9.8-10.2

If the keys will not work then the console is bad and would need replaced.

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.

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.

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.

Unplug unit remove motor shroud then start calibration procedure.
Press the Stop and the Speed Up keys down while inserting the safety key. If you cannot get into calibration then upper console needs to be replaced.
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. At this point if it show 2F FF or Fail then upper console needs to be replaced.
Press either incline key and the incline will calibrate automatically
BE CAREFUL, THE TREADMILL WILL RUN AT FULL SPEED IN THIS NEXT MODE! DO NOT STAND ON 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.

The standard calibration procedure to calibrate an Icon treadmill is done by holding down the speed up and stop keys while inserting the safety key or putting the key in place (if magnetic). If your keypad is not responding, because your treadmill keypad has failed or the console computer has failed. In these cases, the keypad can be replaced in limited instances or the console has to be replaced.
Now if you are able to get in calibration mode then Press the Stop key one time. The Time window should read EP:2P. Some newer models may also say FP, Pass, This means that it passes the EPROM test. If it shows ff or 2f your upper console will need to be replace.
Next step if eprom passes: Press either incline key and the incline will calibrate automatically.
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 you get the the number to 85 and the belt does not move , on the lower board you will see a like flicker that would be the speed control this tells you that the upper console and terminal cable is good ,but lower board defective.

Try this calibration procedure.
Turn the power switch on. Remove the safety key. Hold the Stop and Speed Up or Speed Plus buttons down then insert the safety key.
The display should show some numbers.
Press the stop key one time and the display should show some other numbers and some 00's. Press the Incline Up button and see if the Incline begins to move, if it does let it go all the way up and then all the way down, wait a few seconds after it stops, then hit the stop key 4 times. It should be calibrated. If it didn't move then the board or the incline motor is bad.
