What to Do If Your Drive Motor Is Going Bad

If you suspect your drive motor is going bad, don’t ignore the problem. Continued use could cause further damage to your treadmill. Instead, take the following steps:

  1. Check the Symptoms: Confirm the signs mentioned above. Is the treadmill behaving unusually? Is it making strange noises?
  2. Consult the Manual: Your treadmill’s user manual may have troubleshooting tips specific to your model.
  3. Contact the Manufacturer: If you’re unsure about the problem, it’s best to reach out to the manufacturer’s customer service. They can provide guidance and may be able to diagnose the issue over the phone.

Testing the Drive Motor

Testing the drive motor involves checking its continuity with a multimeter. Here’s a simple step-by-step guide:


  1. Unplug the Treadmill: Safety first! Always unplug the machine before doing any repair work.
  2. Access the Motor: Remove the motor cover as per your treadmill model’s instructions.
  3. Disconnect the Motor Wires: Disconnect the motor wires from the power supply. You might need to take a photo beforehand to remember where each wire goes.
  4. Set the Multimeter: Set your multimeter to the lowest setting for Ohms of resistance.
  5. Test the Motor: Touch the multimeter probes to the motor’s terminals. A reading of zero indicates a shorted motor, while a high reading suggests an open motor. Both are signs of a bad motor.

When to Call a Professional

If you’re uncomfortable testing the motor yourself, it’s time to call a professional. Look for a certified fitness equipment repair expert in your area. They have the skills and tools to accurately diagnose and fix the problem. Hopefully you have a ServiceRX location near you.

Replacing the Drive Motor

If your drive motor is indeed bad, you’ll need to replace it. Here’s how:

  1. Order a Replacement: Purchase a new drive motor that’s compatible with your treadmill model. You can find these online or at specialty fitness stores.
  2. Remove the Old Motor: Unbolt the old motor from the treadmill frame, remove the drive belt and disconnect the wires.
  3. Install the New Motor: Bolt the new motor in place, reinstall the drive belt, and reconnect the wires. Make sure everything is secure before moving on.
  4. Test the Treadmill: Plug in the treadmill and start it at a slow speed to test the new motor. If everything works as it should, you’re good to go!

Cost of Drive Motors

The cost of a new drive motor can vary depending on whether it’s for a residential or commercial treadmill. Residential treadmill motors typically cost between \$100 and \$300, while commercial treadmill motors can range from \$300 to \$600.

Preventive Maintenance for Treadmill Drive Motors

To avoid future drive motor failures, regular maintenance is key. This includes:

  • Proper Use: Don’t exceed the treadmill’s weight limit, and avoid running at top speed for extended periods.
