Pull the hood off. Stand on the sides of the walk platform and start the belt at 4mph. Take one foot and step on the walk belt hard. Look at the pulley on the front roller. Does the pulley continue to turn while the roller stops? If so, the pulley is slipping in the roller (which is a press fit). Replace the front roller or remove the motor belt from the pulley.Align the pulley with the pulley on the motor by tapping with a mallet. Drill an 1/8 hole throught the pulley and roller. Countersink the pulley hole so a small head screw will be under the pulley groves. Install screw in this hole. This is called pinning and is a pemanent fix. If both the pulley and the roller stop together when the belt is stepped on the motor belt is loose. If only the walkbelt stops when stepped on, the walkbelt is loose.

I could be wrong here but i would be inclined to have the electric motor checked out by a electric motor rewinding specialist .

You will need to loosen the rear roller off 8-10 turns on both sides to reinstall the motor drive belt...

Hi,

It sounds like you have a drive motoer failing. The only other place that can be load or making noise is the front and rear roller. The rollers bearings when failing make a "popping" or "clicking" noise, and increases as you speen up. The motor "growls", and the faster you go the noise is..... well loud. The way to confirm this is to remove the motor hood, then start the treadmill on power/speed level 3. Be very carefull, and use a broom stick (wooden) to put on the drive motor while it is running. You should be able to "feel" what you are hearing. You should then raise the speed, and you will then feel the increase as well.

The replacement motor is around $200.00.

Hope this helps

Its sound like either a speed sensor not functioning may need adjusting or replacement refer to your owners manual on page 25 and 26 for this procedure. Now if you complete the adjustment and have the same problem, then you can test this sensor by using a multi meter on continuity setting follow the black connector to the lower board disconnect it and place leads on to connector MAKE SURE you have a good connection when testing. Then move the running belt and the front pulley which has a magnet, have the magnet move back and forth this will open and close the sensor circuit if good then it is the motor control board replace it, if not replace the sensor.

These units only have a calibration mode. The High end units generally will have that. If this is a Epic Then this calibration procedure should work.
Press the Stop and the Speed Up keys down while inserting the safety key. 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. 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 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 movable center and is located near the three small speed wire connections labeled H, W, & L and is on the same edge of the board and the red and black motor wires are located. 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. THIS IS A VERY IMPORTANT STEP BECAUSE YOU WILL GET AN ERROR MESSAGE IF THIS STEP IS SKIPPED. 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 single most cause of no motor output is failure of the DC motor control. Look for any test lights on the power boards beneath the motor hood. Use caution when removing the motor hood because you may still have electricity ( capacitors are charged) in the motor area even if the treadmill is unplugged.
If you have a multimeter, you can test to make sure you have DC output from the controller spades ( Drive Motor Connectors) by clipping on them and then pressing the start key you should have a DC voltage reading if not the controller board is defective.

The motor can be tested by using a simple DC cordless drill or lantern battery this will turn the motor if the motor is good the controller board will need replacement , if not their won't be any belt moment the problem is the motor then the motor will need to be replaced. ( if you don' t have a multi meter this method of testing simple and easy)

Try Re-Calibrating 1st, here's how.
With the Treadmill off, press and HOLD the SPEED UP & STOP
keys, while holding the speed up & stop keys insert the Safety key (Magnet) release the speed up & stop keys. now press and release the stop key. now press the "incline up key" let the treadmill go to max incline,after it stops press and hold the "incline down key" let it go to minimum (completely lowered) you should now be re-calibrated.

What I have done, is remove the case to access the incline assembly. tyically a black tube looking thing with a small motor attached to its side. at the end of this motor, you may see the shaft to the motor, with a slot cut in it,.like a flat head screw driver. use a cordless drill with a standard bit attached to rotate the motor manually.

Check the speed sensor an its positioning. If its ok then the motor or the motor control board is faulty.
