Incline is not working properly, it goes all the way up and down a little and it stops, motor seems to be working properly but cannot calibrate on incline 0% or work properly

If you've already replaced the lift motor on your Proform 400s Treadmill and the incline still won't work properly, there may be other underlying issues that need to be addressed. Here are a few troubleshooting steps you can try:
Check the wiring: Ensure that all the wiring connections related to the incline mechanism are secure and properly connected. Loose or damaged wiring can cause issues with the incline functionality.
Inspect the incline motor and gears: Examine the incline motor and gears for any signs of damage, misalignment, or obstruction. Ensure that the gears are engaging properly and that there are no obstructions preventing the incline from moving up and down smoothly.
Reset the treadmill: Perform a full system reset on your treadmill. This can often resolve minor software glitches or issues that may be affecting the incline function. Consult your treadmill's user manual for instructions on how to perform a reset.
Contact customer support: If you have followed the above steps and the issue persists, it is recommended to reach out to the customer support of Proform or the retailer from whom you purchased the treadmill. They should be able to provide further troubleshooting guidance or arrange for professional repair assistance if needed.
Remember to exercise caution when working with electrical components or performing any repairs on your treadmill. If you are unsure or uncomfortable with the process, it is advisable to seek assistance from a qualified technician or the manufacturer's customer support to ensure proper diagnosis and resolution of the issue.

You probably need to calibrate it...

Best to you.

Method 1: Press Stop and Speed Up, Insert the Key
To calibrate the incline, press and hold the stop and speed increase buttons. While holding the buttons, insert the safety key. The machine will now be in calibration mode. Press the Stop button once. Then, press one of the incline buttons to begin the calibration. It is recommended that you do not stand on the machine while the calibration is taking place.
The machine will move to its highest incline position, then to its lowest decline position. Please wait for the machine to come to a complete stop. When the machine stops moving, the calibration is complete. Remove the safety key from the console to exit calibration mode.
Method 2: Press the Stop Button, Insert the Key
To calibrate the incline, press and hold the stop button. While holding the button, insert the safety key into the console. The machine will now be in calibration mode. Press the stop button once. Then, press either the incline up or incline down button to begin the calibration. It is recommended that you do not stand on the machine while the calibration is taking place.
The machine will move to its highest incline position, then to its lowest decline position. Please wait for the machine to come to a complete stop. When the machine stops moving, the calibration is complete. Remove the safety key from the console to exit calibration mode.

You need a new incline motor, The incline sensor is bad. One way to test is to pull the black and red off the MCB and applied 120 volts on the black (up) or Red (down) wire and see the incline motor move. If it does then the MCB is bad

it is trying to calibrate itself, let it go the whole way up and then down without interrupting it. Then it should be fine.

try thisSometimes incline motors will get frozen in position and need broke free. Try this:
take the motor cover off and take the screw out of the bottom of the incline motor that is attached to the screw assembly. Once you remove the screw you should be able to break the incline motor free. run the incline up and down with the screw still off( laying the treadmill on its side may make this easier). Once it goes up and down (hold the screw so it goes in and out) reattach it then run the calibration described below. If it was just stuck it should work fine.

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
6. remove safety key and try

If these instructions do not work to fix the incline motor
check your main harness running down the right leg for breaks in the wires or a loose connection if nothings found you can switch the red and black wires on the incline motor terminal block and see if it goes down. If it does you know you are only getting voltage to one side of the motor. There is a schematic under the motor hood that tells you what the voltage should be when you press the up or down keys. Use a multi-meter to see if you are getting the correct voltage coming from the console to the motor control board and then from the board to the motor. If no voltage from console-replace console if you have voltage from console but not from board - replace board and finally if you have voltage from console and from board replace motor. You will need to test the voltage both when pressing the up key and the down 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.
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.
