What causes treadmill to slow down and then speed up?

Adjust belt tension if the belt is too loose or too tight. If belt tension is okay, then you might need to add belt lubricant to the walking board so the belt slides easily across the board. A weak drive motor can cause the belt to slow down when you step on the treadmill.

Why does my treadmill keeps speeding up?

You may have a short in the motor. If you turn the machine on and have erratic speed, you could have a problem in the DC board or the motor or both. With a simple multi-meter, you can test on the continuity scale to see if you have a closed circuit between either DC motor lead and the common earth ground.

Why does my treadmill hesitate?

Adjust the tension —If the treadmill running belt feels like it is “slipping” or hesitating when you plant your foot during a run, the tension on the treadmill belt may have to be increased. This is a common and easy tweak to make.

How do I know if my treadmill speed sensor is bad?

Pull the connector from the circuit board. Test the continuity of the speed sensor wiring circuit with a voltage meter. If the meter shows continuity, the speed sensor must be replaced.

Where is speed sensor on treadmill?

The speed sensor on an electronic treadmill is most likely located at the front roller near the motor assembly, where it counts each revolution to calculate speed and distance.

How do I fix my treadmill that keeps stopping?

Treadmills require lubrication to limit the amount of friction between the platform and belt. When the friction increases to a certain point, the machine is automatically set to power off. This may be the cause for the machine to stop working suddenly. Try lubricating the belt.

Why is my treadmill dragging?

The Pulley on the Front Roller May Have Lost its Grip In case of a slippage, there will be a misalignment between the pulley and the front roller which will also cause the treadmill belt to misalign and ultimately slip.

What does speed sensor in treadmill do?

The treadmill speed sensor records the revolutions per minute of the front roller and the computer converts this reading to miles per hour. On most models, the speed sensor is connects to a circuit board that interfaces with the treadmill control panel.
