A ProForm treadmill is a popular choice for individuals who want to enjoy the convenience of working out at home. However, like any other piece of equipment, treadmills can sometimes encounter issues that disrupt their functionality. 

In this article, we will explore common problems that may lead to your ProForm treadmill not working and some steps for troubleshooting ProForm treadmill.

Power and Display Issues

One of the most common problems with treadmills involves power and display malfunctions. If your ProForm treadmill fails to power on or the console display is not functioning properly, follow these steps:

  • Double-check that the power cord is securely connected to the treadmill and that the other end is plugged into a working electrical outlet.
  • Look for a reset switch on the treadmill’s frame or near the power cord. If the circuit breaker has tripped, reset it and try powering on the treadmill again.
  • Ensure that the power switch on the treadmill is in the “on” position. Some models have a safety key that needs to be properly inserted for the treadmill to turn on.
  • If the display is flickering or not showing any information, there may be loose or damaged wiring connections. Carefully remove the console cover and check for any loose or disconnected wires. Reconnect them securely or replace damaged wires if necessary.

Belt Slippage or Misalignment

If you notice that the treadmill belt is slipping or misaligned, it can significantly affect your workout experience. Follow these troubleshooting steps to address this issue:

  • Most ProForm treadmills have a tension adjustment feature. Consult your user manual to locate the tension adjustment bolts or knobs. Gradually tighten the bolts in small increments until the belt is properly tensioned.
  • To ensure proper alignment, start by loosening the bolts or knobs at the rear of the treadmill. Next, carefully adjust the belt by aligning it with the center of the treadmill deck. Once aligned, tighten the bolts or knobs.
  • Over time, the treadmill belt may require lubrication to reduce friction. Follow the manufacturer’s instructions to apply the appropriate lubricant to the belt. Lubrication should be performed periodically, depending on your usage and the specific model.

Noisy Operation

A noisy treadmill can be distracting and annoying. Here are some steps to troubleshoot and reduce the noise:

  • As mentioned earlier, ensure that the belt is properly tensioned. An overtightened or loose belt can cause excessive noise during operation. Adjust the tension as needed following the manufacturer’s guidelines.
  • Lack of lubrication can contribute to excessive noise. Regularly applying lubricant to the belt can reduce friction and minimize noise. Be sure to use the appropriate lubricant recommended by the manufacturer.
  • Over time, various components may become loose due to vibrations. Carefully inspect the treadmill for loose screws, bolts, or parts. Use the appropriate tools to tighten them securely.

Error Codes and Malfunctions

ProForm treadmills often display error codes or malfunctions on their console to indicate specific issues. Here are a few common error codes and troubleshooting steps:

  • This error typically occurs when the speed sensor fails to detect belt movement. Check the sensor alignment and clean any dirt or debris that may be obstructing it. If the issue persists, the speed sensor may need replacement.
  • If you encounter this error, ensure that the incline motor is properly connected and the wiring is intact. If the problem persists, professional assistance may be required.
  • This error indicates a problem with the treadmill motor. Check the motor connections and inspect for any signs of damage. If the issue persists, contact customer support for further assistance.

Heart Rate Monitor Inaccuracy

Many ProForm treadmills are equipped with heart rate monitoring capabilities to help users track their cardiovascular performance. However, sometimes these monitors can provide inaccurate readings. 

If you’re experiencing issues with your treadmill’s heart rate monitor, try the following troubleshooting steps:

  • Make sure you’re placing your hands or gripping the heart rate sensors correctly. The sensors are typically located on the handlebars or console grips.
  • Verify that the sensors are securely connected to the treadmill’s console. Loose or disconnected wires can lead to inaccurate heart rate readings. If necessary, carefully inspect the connections and reattach any loose wires.
  • For accurate readings, ensure that you maintain consistent contact with the heart rate sensors throughout your workout. Avoid gripping too tightly or placing excessive pressure on the sensors, as this can disrupt the signals.
  • If the built-in heart rate monitor continues to provide inaccurate readings, you may consider using an external heart rate monitor, such as a chest strap or wristband, that is compatible with your ProForm treadmill.

Uneven Running Surface

An uneven running surface can not only affect your running performance but also increase the risk of injury. 

If you notice that your ProForm treadmill’s running surface is uneven, follow these troubleshooting steps:

  • Use a bubble level to ensure that your treadmill is placed on a flat and level surface. Adjust the leveling feet or base as necessary to achieve balance. A leveled treadmill will help prevent the running surface from tilting or wobbling during use.
  • Examine the treadmill deck and belt for any signs of damage, such as cracks, tears, or warping. Damaged components can lead to an uneven running surface. If you detect any issues, contact ProForm customer support for guidance on replacing the deck or belt.
  • The rear roller plays a crucial role in maintaining the stability and evenness of the running surface. If you notice any unevenness, check the rear roller bolts located at the back of the treadmill.
  • Refer to your user manual for instructions on adjusting the belt tension. An overly tight or loose belt can cause unevenness during your workout. Follow the manufacturer’s guidelines to achieve the correct tension for a smooth and even running surface.


Owning a ProForm treadmill provides you with a convenient and efficient way to stay fit in the comfort of your home. However, encountering issues with your treadmill can be frustrating. 

By following the troubleshooting ProForm treadmill tips outlined in this article, you can address common problems that may arise, such as power and display issues, belt slippage or misalignment, noisy operation, and error codes. 

Remember to consult your user manual for model-specific instructions and, when in doubt, contact ProForm customer support for professional assistance. With the right troubleshooting approach, you’ll be back on track with your fitness routine in no time.
