We don't have any specific instructions for replacing the walking belt on your treadmill. The basic instructions are:

Disconnect the power from the treadmill and remove the screws holding the motor hood on, and remove the hood.

Remove the belt adjusting bolts front and rear and run the drive belt off the front roller or motor pulley.

Remove the side rails and remove the screws holding the walking board on the frame.

Lift the front and rear rollers and slide the walking belt off the walking board toward the right side of the treadmill.

Reverse this process to install the new belt.

Desirea, The side rails are not connected to the walking board. They are connected to the frame which would do no good to remove these screws. The walking board is connected to the frame with screws that are hidden by the Foot Rail which has no visible means of removing. I am afraid if I force it, it may break. How is it fastened to the walking board? Hopefully it is not glued. If I get this Foot Rail off without damaging it the rest is no problem to replace.

After looking that the diagram, it seems like you would only need to remove the front and back cover to get to the rollers. I have included an image of your treadmill the covers are Item #23 and #78 on the diagram.

I did some more research for your specific model and I was able to locate instructions for your brand of treadmill. I hope this answers all your questions.

 

Step 1

Remove the safety key from the power switch at the bottom of your Lifestyler treadmill. Turn it off and remove the power cord from the wall receptacle.

Step 2

Take out the six screws holding the motor hood onto the Lifestyler treadmill frame. Two screws are on each side of the motor hood and two in the back. Lift the motor hood off the treadmill frame.

Step 3

Mark the front roller adjustment bolt with a marker at the point the bolt meets the front belt roller on the treadmill. The Lifestyle front roller adjustment bolt is located on the front of the right foot rail.

Step 4

Remove the rear roller adjustment bolts and the handrail washers from the rear of the right and left foot rails with the hex key provided with the Lifestyler treadmill. If you do not have the hex key, you need to choose one that fits the bolts from a hex key set. Turn both bolts counterclockwise to remove them from the rear belt roller. Make a visual note of where the bolts sat in the rear roller end cap to get an estimated idea of how far to replace the bolts once you install the new walking belt. You do not have visual access to the bolt locations in the rear belt roller because of the rear roller end cap.

Step 5

Pull the rear roller end cap from the Lifestyler treadmill frame. Use a large slotted screwdriver to pop the left and right foot rails off the treadmill frame and walking platform. Completely remove the front roller adjustment bolt and handrail washer from the front belt roller with the same hex key you used on the rear roller adjustment bolts.

Step 6

Remove the two platform screws located at the middle and the front of the walking platform on each side of the walking belt. Remove the rear isolator screw at the rear of the walking platform on each side of the walking belt. The screws thread through the walking platform and the isolators, attaching the platform to the Lifestyler treadmill frame. The three isolators on each side of the walking platform hold the walking platform in place on the frame.

Step 7

Lift the walking platform from the frame of the Lifestyler treadmill, making sure you hold the front belt roller securely to the pulley/flywheel. The pulley/flywheel is located on the left side of the front belt roller and attaches to the roller motor.

Step 8

Recruit a friend to pull the old walking belt from the front and rear belt rollers and slide a replacement Lifestyler walking belt onto the rollers. Have your friend verify that the replacement belt centers between the two belt guides underneath the walking platform.

Step 9

Lower the walking platform onto the treadmill frame. Make sure the platform sits between the isolators, and replace the platform screws and the rear isolator screws. Snap the left and right foot rails onto the walking platform and treadmill frame.

Step 10

Replace the rear roller end cap onto the Lifestyler treadmill frame. Thread the handrail washers over the rear roller adjustment bolts and insert them through the end cap and into the rear belt roller but do not tighten them.

Step 11

Thread the handrail washer over the front roller adjustment bolt and insert the bolt into the front belt roller. Tighten the front roller adjustment bolt until the mark you placed on the bolt in Step 3 meets the front belt roller.

Step 12

Alternate turning the rear roller adjustment bolts 1/4 turn clockwise until the replacement walking belt will only lift from the Lifestyler walking platform 3 to 4 inches. Replace the motor hood onto the treadmill frame.

Step 13

Plug the Lifestyler power cord into the wall receptacle. Reinsert the safety key into the console and set the walking speed on the treadmill between 3 and 5 mph. Walk on the replacement walking belt to check for slipping or sticking.

Step 14

Turn the rear roller adjustment bolts on the Lifestyler treadmill 1/4 turn counterclockwise, alternating between each bolt to loosen a sticking walking belt. Turn the same bolts clockwise to tighten a slipping walking belt.

A:

If you measured around 53 volts dc across terminals A+ and A-, the motor should be running. The voltage will vary across A+ and A- depending on the speed the treadmill is set for. The motor should run around 3 mph on 18-20 volts dc.

I am sending some images with troubleshooting instructions using the leds on the motor controller and the power board.

If you have questions, reply on this thread and I will be glad to help.

A:

The links Barbara H sent have good information. I would check the belt for wear and lubrication before testing electronic parts. The problem is very likely in the walking belt.

The motor controller will lower the voltage to the motor if it detects high amperage. It will turn the motor off to protect it if the amperage gets too high.

To test the motor controller, start the treadmill without a load and measure the dc voltage to the motor. Get someone to walk on the belt and if the controller increases the voltage by 5 or more volts, the controller is working.

If a motor fails it will usually become noisy and you can see arcing inside the motor.

If you have questions, reply on this thread with details of the tests you have done. I will be glad to help.
