I have a Image 15.5 Treadmill, it turn on, Incline...

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?

Bad contact in the switch

the wires for the incline motor are reversed on the board.if you follow the wires you should have 2 that look identical. reverse where they connect on the board and see .

replace home switch sensor

RUN the software calibration for easy diagnostic, and fix it. Go to THE HOOD cover for the motor and follow the steps or use the owner manual.
God bless you

Renee, Here is how to recalibrate the incline motor. Read all of it It will be good to keep.
Plug in your treadmill, do not stand on the walking belt. Hold down the "Stop" and "Speed +" key and insert the safety key or magnet, let go of the two keys. Now press "Stop" key once. This puts you into the level 2 of calibration. Press the "Speed +" key slowly until you see 85 on the console, (at this point the display is going to show the percentage of motor usage and also the actual walking belt speed) at 85% motor usage your top speed should be between 10 and 10.5 MPH or (of 12 and 12.5) depending on the treadmill. You must know your treadmills top speed. (Important the motor may be damaged if you set the maximum speed higher than the maximum speed that your treadmill is made for). If the speed is higher than 10.5 or 12.5 then you need to turn the potentiometer down to the correct level. If the speed it to low you need to turn the potentiometer higher. Once the speed is correct you are done calibrating the speed. Press the (-) speed key to lower the percentage to (0). Next press the incline (+) button, this will make the incline motor go all the way to the maximum incline and come all the way down to the level position. Then remove the safety key and the treadmill will reset into the normal manual mode, when you re-insert the safety key. Matt

The NordicTrack is a treadmill designed for in-home use. It offers a speed range of 0 to 10 mph and an incline range of 0 to 10 percent. It folds up vertically to save space when you aren't working out and can be rolled to a different room. The console has 16 preset workout programs and features iFit interactive technology. If you have problems with the console or walking belt, you can often fix them yourself with some basic troubleshooting steps
Instructions

1. Power Turns Off When You're Using the Treadmill
   • 1 Check the reset switch on the bottom of the treadmill near the power cord. If it has tripped, the top of the switch will protrude. Wait 5 minutes then press the switch.
     
   • 2 Check that the power cord is plugged in completely. If it is plugged in, unplug it, wait 5 minutes then plug it back in.
     
   • 3 Remove the magnetic key from the console then reinsert it.
     
   The Console Won't Turn Off
   • 1 Insert the magnetic key into the console. Your C2500 is stuck in demo mode if the console won't turn off after you remove the magnetic key from the console.
     
   • 2 Hold the "Stop" button down for a few seconds.
     
   • 3 Press the "Speed" down (-) button. Remove the magnetic key.
     
   The Incline Does Not Change Correctly
   • 1 Press and hold the "Stop" and the "Speed" up (+) button. While holding the buttons, insert the key into the console, then release the buttons.
     
   • 2 Press either the "Incline" up or down arrow button. Wait while the incline raises and lowers. This recalibrates the incline system.
     
   • 3 Remove the key from the console.
     
   Walking Belt Slows
   • 1 Unplug your C2500 and remove the key from the console.
     
   • 2 Turn both rear adjustment bolts, located on the back of the walking deck, to the left, a 1/4 turn.
     
   • 3 Lift the edge of the walking belt in the middle of the deck. You should be able to lift it 2 to 3 inches off the walking platform. If the belt is still too tight, loosen the bolts another 1/4 turn each.
     
   • 4 Plug the treadmill in and reinsert the console key. Walk on the belt at a slow speed to see if it still slows. Repeat Step 2 if necessary.
     

Does it make any noise? You can always isolate the incline motor from the rest of the treadmill and use a 110v jumper cord from white to black or white to red and check to see if the incline motor works with the jumper cord. If so than you know the problem is in the electrical of the treadmill.

console is bad

The motor controller. If everything works but the belt will not turn, that's 99.99% your problem. I can get you a controller and walk you through replacing it. [email protected]
