Proform 1450 treadmill incline problems

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.

if the motor tries to work but incline does not go up something is jammed on the treadmill or the incline motor is bad

Run please the software calibration for easy diagnostics+and fix it.

God bless you

Please RUN the software caibration for diagnose, troubleshooitng, and fix it Maybe you have speed sensor faulty or bad adjustment, clean it and tight wires connector.
God bless you

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.

ProForm Treadmills have a reset procedure for the incline function. With the key inserted in the console, activate the incline; while the incline is changing, remove the key. Wait 30 seconds, then replace the key. The incline should to maximum, then to minimum, resetting its limits. It worked for mine just 10 minutes ago; the procedure is in the manual if you have it. Good luck!

Open the cover where the main motor is there
Tight the connector for Incline motor, and clean it with special contact cleaner for electronic.
2) See if there are wires loose,
3) Measure the 110 vac for forward and backward,
4) If there are , measure the l. switch or Capacitor for faulty and replace.
5) If there nOT 110VAC in forward or backward, replace the controller board motor.
6) If there are 110VAC, replace the Incline motor.
Blessing.

Try to calibrate the incline threough the calibration mode.
