Maximizing Your Treadmill's Potential: 10 Expert Troubleshooting Techniques

Treadmills are a popular piece of exercise equipment, both in the gym and in the home. They are versatile, convenient, and effective for getting a cardiovascular workout. 

However, like any machine, treadmills can sometimes experience issues that can affect their performance. In this article, we will share 10 expert troubleshooting techniques to help you maximize your treadmill's potential.


  • If your treadmill's speed seems off, it may need to be calibrated. This can be done by following the manufacturer's instructions for recalibration. 

  • Often, this involves adjusting the tension on the drive belt or recalibrating the sensor that detects the speed of the treadmill.

Belt Tension: 

  • If the belt on your treadmill is slipping or loose, it may need to be adjusted. Most treadmills have a tension adjustment screw that can be turned to tighten or loosen the belt. Follow the manufacturer's instructions for proper belt tension.

Belt Alignment: 

  • If the belt on your treadmill is off-center or rubbing against the sides, it may need to be realigned. This can be done by adjusting the bolts or screws that hold the deck in place.


  • The belt on your treadmill can become dry and brittle over time, which can cause it to wear out faster. 

  • To keep the belt in good condition, lubricate it with a silicone-based lubricant every few months. Check the manufacturer's instructions for specific lubrication recommendations.

Electrical Issues:

  •  If your treadmill is not turning on or is experiencing electrical issues, it may be a problem with the power cord or the circuit breaker. 

  • Check the power cord for any damage, and make sure the circuit breaker is in the "on" position.

Error Codes:

  •  Many modern treadmills have error codes that can indicate what is wrong with the machine. Check the owner's manual for a list of error codes and what they mean.

Motor Issues:

  •  If your treadmill's motor is making unusual noises or is not functioning properly, it may need to be serviced. This should be done by a professional technician.

Console Issues: 

  • If the console on your treadmill is not working properly, it may be a problem with the wiring or the display screen. Check the wiring for any damage or loose connections.

Shock Absorption: 

  • The shock absorption system on your treadmill can wear out over time, which can affect the machine's performance and safety. Check the shock absorption system regularly and replace any worn out components.


  •  Regular maintenance can prevent many common issues with treadmills. Clean the machine after each use, lubricate the belt every few months, and check the bolts and screws for tightness.

In addition to these troubleshooting techniques, here are a few other things to keep in mind:

Safety First: 

  • Always follow the manufacturer's safety guidelines when using your treadmill. This includes using the safety key and keeping the machine in a safe location.

Proper Use: 

  • Treadmills are designed for walking or running, not jumping or other high-impact exercises. Use the machine as intended to prevent damage or injury.

Regular Use: 

  • Regular use of your treadmill can help prevent issues such as belt wear and motor problems. Aim to use your treadmill at least a few times a week.

Professional Help:

  •  If you are unsure how to troubleshoot an issue with your treadmill, or if the problem seems serious, seek the help of a professional technician.

In conclusion, a well-maintained treadmill can provide years of effective workouts. By following these expert troubleshooting techniques and practicing regular maintenance, you can maximize your treadmill's potential and get the most out of your home workout routine.

Over the years though, we've certainly earned our specialties in "elliptretics" and "treadmllology" - and Clark really did start out by using a stethoscope to diagnose faults with treadmills ( hence the company name).

In fact, we've been in this industry since Clark was still In school in 1987 - when the commercial fitness equipment Industry was only a few years old.
