Your treadmill is one of the most used machines in your fitness setup — but even the best ones need care. Ignoring small issues can lead to costly repairs or even accidents. Here are five signs that tell you it’s time to call a professional.

If your treadmill starts squeaking, grinding, or thumping, it’s a clear signal something’s wrong — often with the belt, rollers, or motor.

A loose or misaligned belt can cause sudden jerks while running, which is both unsafe and uncomfortable.

This usually means the motor or wiring is under strain. Stop using the treadmill immediately and book a service.

If speed, incline, or buttons stop responding, it may be an electrical or software issue that needs expert attention.

A wobbling deck or uneven base can damage the frame and increase your risk of injury.

Regular preventive maintenance can help you avoid these issues altogether.
