In short
Most new noises come from a dry belt (squeak or rub), loose fixings (rattle), a seam or debris passing the rollers (regular click), worn roller bearings (grinding or whine) or the floor itself (thump). Unplug, check for debris, tighten fixings, lubricate if the deck is dry and re-centre the belt. A grinding or burning smell needs the maker or a technician.

Every walking pad makes some noise: a motor hum, the swish of the belt and the sound of your feet. What matters is a change. A new squeak, a click that keeps time with the belt or a thump that travels through the floor usually points to a specific part. The good news is that most of these causes are simple to check at home. This guide matches each sound to its likely source and gives the order to work through. Procedures differ between models, so keep your manual to hand and follow it where it differs.
Which sound points to which part
Listen with the machine running at a slow walking speed, first with nobody on it and then while you walk. A noise that only appears under load points to the belt, deck or drive. A noise that is there with the belt empty points more towards the rollers, motor or a loose cover.
| Sound | Likely source | What to do |
|---|---|---|
| Squeak or squeal as you step | Dry deck, belt rubbing | Lubricate with the maker's silicone |
| Rhythmic click once per belt turn | Belt seam, debris, or belt touching frame | Check for debris and tracking |
| Rattle or buzz | Loose screws, covers or handrail | Tighten fixings, check the remote holder |
| Grinding or rising whine | Roller bearings or motor | Stop using, contact the maker |
| Thump or boom through the floor | Footfall on a hollow floor | Use a dense mat and a softer step |
| Scraping at one edge | Belt drifting off centre | Re-centre with the rear bolts |
Squeaks: usually a dry belt
A squeak that comes with each footstep is the most common complaint. As the silicone under the belt wears away, the belt drags on the deck and squeals under load. Lift the belt edge with the machine unplugged and feel the deck. If it is dry, apply the lubricant your maker recommends and walk slowly for a few minutes to spread it. See how to lubricate a walking pad for the method.
Squeaks can also come from the frame flexing at a joint or from a folding hinge. Check the hinge bolts on folding models and the handrail fixings on 2-in-1 pads.
Clicks: seams, debris and tracking
A click that repeats at the same interval is often the belt seam passing over a roller. A light, even tick can be normal on some belts. A louder click that has appeared recently may mean the seam is lifting, or that something such as a hair tie or a coin is trapped under the belt.
If the belt has drifted to one side, its edge can catch the frame or motor cover and click or scrape. Re-centre it using the rear tension bolts in small, equal adjustments. Our guide on how to adjust a treadmill belt explains which bolt to turn.
- 1
Unplug and remove the safety key.
- 2
Turn the belt slowly by hand and look underneath with a torch.
- 3
Remove any debris and inspect the seam.
- 4
Check the gap between belt edge and frame on both sides.
- 5
Adjust tracking if the belt is closer to one side.
Rattles, grinding and motor noise
Rattles usually come from loose screws on the motor cover, side rails, handrail or display. Vibration loosens them over time. Go round the machine with the correct screwdriver or Allen key and nip each fixing up, without forcing anything.
Grinding, a rising whine that changes with speed, or any burning smell is different. These can point to worn roller bearings, a failing motor or a problem with the drive belt. Stop using the machine and contact the maker or a qualified technician. Do not open the motor cover on a machine under warranty unless the maker tells you to.
Note:Unplug before inspecting. If you smell burning or see smoke, switch off at the wall, unplug and do not use the machine again until it has been checked.
Thumps: often the floor, not the machine
A walking pad sits low, so footfall goes straight into the floor. Suspended timber floors, common in UK upstairs rooms and older flats, can amplify that into a thump that neighbours hear more than you do. Placing a dense rubber mat under the machine and walking with a lighter step both help.

Frequently asked questions
Why is my treadmill making a clicking noise? The most common causes are the belt seam passing a roller, debris under the belt, or a belt that has drifted and is catching the frame. Check those before suspecting the motor.
Is it normal for a walking pad to squeak? Not usually. A new squeak normally means the deck needs lubricant or a fixing has loosened. Lubricate as your manual says and check the hinge and cover screws.
Why is my walking pad louder downstairs than in the room? Footfall travels through the floor structure. A dense mat and a softer step reduce it more than anything you can change on the machine.
Should I keep using a treadmill that grinds? No. Grinding can mean bearing or motor wear, which gets worse with use. Stop and contact the maker or a technician.
