Precor 5.17i lift wobbly

I have a Freemotion i5.3 Incline Trainer. When I run on it at 4+ MPH it makes loud bangs when my foot land on the platform. I usually walk on it at higher incline and just recently started running on it. The bangs are much louder at 0% incline than at higher inclines for the same speed. What might be the problem?

When I think 'higher lift' and leather - I think 'less pressure on the material' Ergo, release pressure on the pressure foot. Usually atop the left side of any machine. Press down on outer ring, to release pressure. Test on extra material. Hope this helps.

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

Precor Error E2, Lift Error Probable Cause Error would occur if the incline is unable to move or if the incline position potentiometer is not functioning. When this error occurs, all lift motor and drive motor motion is ceased and the display will go blank except for the error displayed.
Corrective Action Troubleshoot as errors 40 and 42.

Precor Error Code E2

most prob one of sensor / connection gone bad

Is the ramp steel or aluminum? (steel is magnetic, aluminum is not) If steel, the ramp probably broke - if you tip it over, you may be able to see the tear in the metal. Replace the ramp.

It may be either the front shroud is installed incorrectly or broken, or the corkscrew for the incline motor is bent. If it is bent, it would need to be replaced.

Precor Error E4, Incomplete Initialization Probable Cause Indicates that an incomplete upper PCA to lower PCA initialization occurred. When this error occurs, all lift motor and drive motor motion is ceased and the display will go blank except for the error displayed.
Corrective Action Run the initialization program. Caution: The treadmill's running belt will accelerate to the treadmill's maximum speed (12mph). DO NOT stand on the treadmill's running belt during the procedure.

1. Set the on/off switch to the OFF position. Wait a minimum of 10 seconds to allow the internal power supply to discharge.
2. Remove the safety key from the console and set the on/off switch to the ON position.
3. Press INCLINE UP and SPEED DOWN keys together. While pressing these keys, replace the safety switch on the console. Continue holding the INCLINE UP and SPEED DOWN keys until the display goes blank. INIT will appear in the time window of the display. The EEPROM is now clear and reset. After a second, 1.25 will appear in the distance/calories window, 15.0 (the maximum incline) will appear in the incline window, and 12.0 (the maximum speed) will flash in the speed/pace window.
4. Press QUICKSTART to begin the speed calibration process. Power bits will appear in the incline window, the target speed will appear in the time window and the actual speed will appear in the speed/pace window. At the beginning of the process, the target speed will be .5mph. The running belt will start. Once the actual speed reaches .5mph, the target speed will then change to 12mph and the running belt will accelerate until it reaches 12mph, then it will stop.
5. When the running belt stops, the display will return to the user mode and the initialization process is complete.

It doesn't always say low battery - check the battery first. If the battery is fine, then check the lower board and the incline motor.
