Adding a treadmill to your home fitness room gives you an exercise tool you can use any time of the day or night, without having to drive to a health club or wait in line for one of your gym’s treadmills to open up. Of course, having your own treadmill means taking care of your own treadmill. If you purchase a Pro-Form treadmill from Sears, you can troubleshoot many common problems yourself.

Step 1

Look at the power cord if the Pro-Form treadmill won’t turn on. Check that the plug is firmly in the wall socket or surge suppressor and that the surge suppressor isn’t switched off. If the machine still doesn’t come to life, check whether the key is inserted properly in the console and whether the power switch on the frame is pushed in to the right. If the switch protrudes on the right, wait for five minutes and then press down on the right side of the switch.

Step 2

Check the power switch if the treadmill stops working during a workout. If the switch is off, wait for five minutes and then press it down on the right. You can also make sure the power cord hasn’t come loose or remove and then reinsert the key.

Step 3

Hold the “stop” button down for several seconds if the console is still lit after you remove the key from the machine.

Step 4

Remove the motor hood, on the bottom front of the treadmill, to make an adjustment if the console display malfunctions. Take the key out of the machine and unplug the cord. Use a Phillips-head screwdriver to remove the five screws around the hood and then lift the hood off the machine. Turn the pulley at the top of the motor until the magnet on the side of the pulley is next to the reed switch that protrudes from the middle of the motor. Replace the hood, fasten the screws, plug the cord back in and insert the key.

Step 5

Adjust the walking belt if it’s too tight, too loose or out of alignment, using the hex wrench supplied with the treadmill. Remove the console key and unplug the machine. Use the hex wrench to rotate both idler roller screws on the back end of the treadmill about one-quarter turn counterclockwise if the belt is too tight. Turn both screws clockwise about one-quarter turn to tighten the belt. Rotate the left roller screw about one-half turn clockwise if the belt is too far to the left. Rotate the right screw one-half turn if the belt has veered to the right.

Things You'll Need

  • Phillips-head screwdriver

  • Hex wrench (supplied with treadmill)

Tip

If troubleshooting fails, call the number on the back of your owner’s manual to have the treadmill repaired professionally. Keep your purchase receipt as long as your treadmill is under warranty so you can receive any free service to which you’re entitled.

Warning

Read the owner’s manual before you start the Pro-Form treadmill to be sure you’re using it safely.
