If you’re hearing strange noises during your workout, you might be wondering why is my nordictrack treadmill squeaking. That high-pitched sound can be annoying and worrying, but it’s usually a sign of a simple fix. Most squeaks come from a few common areas that you can check yourself.
Why Is My Nordictrack Treadmill Squeaking
A squeak is almost always caused by friction where there shouldn’t be any. When parts rub together without proper lubrication or when something is loose, they create that telltale noise. The key is to figure out which part is the culprit so you can silence it for good.
Common Causes of Treadmill Squeaks
Before you start taking things apart, it helps to know where to look. The noise can come from several places, each with it’s own solution.
- The Belt and Deck: This is the most common source. A dry belt rubbing on the deck creates a loud squeak or squeal with every footstep.
- Rollers: The rollers at the front and back can develop flat spots or their bearings can wear out, causing a rhythmic squeaking.
- The Drive Motor: A failing motor or motor belt can produce a high-pitched squeal, especially under load.
- Loose Parts: Any bolt, screw, or panel that has worked itself loose can vibrate and cause an intermittent squeak or rattle.
How to Find the Source of the Squeak
You need to play detective. Listen closely to pinpoint where the sound is coming from. This will save you alot of time.
- Safety First: Unplug the treadmill from the wall outlet.
- Walk the Belt: Slowly walk the belt by hand with the power off. Listen for the squeak and try to feel for any catching or roughness.
- Check Different Speeds: If you can safely, plug it back in and run the belt at a slow speed. Does the squeak change with speed or only when you walk on it?
- Apply Pressure: While the belt is moving slowly, gently press down on different sections—the sides, the middle. See if the noise changes.
Fixing a Squeaky Treadmill Belt
If the squeak seems to come from the walking surface, the belt and deck are likely the problem. They need proper lubrication to work smoothly.
- Check Belt Alignment: See if the belt is centered on the deck. If it’s rubbing on the side rails, it will squeak. Adjust the rear roller bolts to center it.
- Lubricate the Deck: NordicTrack treadmills require specific silicone-based lubricant. Do not use WD-40 or household oils.
- Loosen the belt so you can lift it up. You should be able to slide it side-to-side easily.
- Apply the lubricant in a zig-zag pattern on the deck under the belt, about the size of a standard sheet of paper.
- Tighten the belt back to the proper tension (you should be able to lift it about 2-3 inches off the deck in the middle).
- Run the Treadmill: Run the belt at a slow speed for a few minutes to spread the lubricant evenly.
Inspecting and Fixing the Rollers
A bad roller will often make a consistent squeak with each revolution. You’ll here it even when you’re not walking on the belt.
- Unplug the treadmill and tip it up safely to access the underside.
- Spin each roller by hand. They should spin freely and quietly.
- Look for any visible cracks, flat spots, or debris wrapped around the axles.
- If a roller feels gritty or doesn’t spin smoothly, the bearings are likely shot. You’ll need to order a replacement roller from NordicTrack.
When the Motor is the Problem
A motor squeal is more piercing and often gets louder as you increase the speed or incline. This can be more serious.
- Motor Belt: Check the small belt connecting the motor to the front roller. If it’s worn or loose, it can squeak. Tighten or replace it.
- Motor Bearings: If the motor itself is squealing, the internal bearings are probably failing. You’ll likely need a professional to replace the motor.
Tightening Loose Components
Don’t overlook the simple stuff. A loose bolt can cause a suprising amount of noise.
- Go around the entire frame with a hex key set and wrench. Check all the bolts you can see, especially where the uprights meet the base.
- Check the motor cover and console shrouds. Plastic panels can vibrate if a clip is broken or a screw is missing.
- Make sure the walking belt is properly tensioned, as mentioned earlier. A too-loose belt can flap and cause noise.
Preventive Maintenance to Avoid Future Squeaks
The best fix is preventing the squeak from starting in the first place. A little regular care goes a long way.
- Lubricate Regularly: Follow your manual’s schedule for lubricating the deck, typically every 130 miles or 3 months of regular use.
- Keep it Clean: Vacuum under and around the treadmill regularly to prevent dust and dirt from getting into the bearings and motor.
- Check for Wear: Every month, lift the belt and feel the deck for excessive wear or warping. A worn deck can damage the belt.
- Avoid Overtightening: When you adjust the belt, don’t make it to tight. This puts extra strain on the motor and rollers.
When to Call for Professional Help
Some repairs are best left to the experts. If you’ve tried the basic fixes and the squeak persists, it might be time for a service call.
- You suspect a major issue with the motor or internal electronics.
- The walking deck is visibly cracked or warped.
- You’re not comfortable working with mechanical or electrical parts.
- The treadmill is still under warranty—tampering might void it.
FAQ About Treadmill Noises
Q: My treadmill squeaks only when I walk on it, not when it runs empty. What does that mean?
A: This almost always points to the belt and deck needing lubrication. Your weight creates the friction that causes the squeak.
Q: Can I use something like Vaseline or cooking oil to lubricate my treadmill?
A: No, never. You must use a 100% silicone-based treadmill lubricant. Other substances will damage the belt and deck, creating a bigger problem.
Q: The squeak sounds like it’s coming from the front. Is that the motor?
A: It could be the front roller or the motor belt. Try to isolate the sound by listening closely with the motor cover off (unplugged first).
Q: I just lubricated it, but it’s still squeaking. What now?
A: Give the lubricant a little time to work in. If it persists after 15 minutes of running, the issue might be a roller, a loose part, or the belt tension might be incorrect.
Q: Is a squeaking treadmill dangerous?
A: Usually, it’s just an annoyance. But a loud squeak can indicate a part is failing, which could lead to a breakdown. It’s best to adress it promptly.
