r/treadmills

How quiet (or loud) is your tread+ ? My question pertains to the actual belt and not the motor that is obviously going to make some noise when active.

The reason I’m asking is because my belt as I’m stepping seems louder than before, like maybe something is loose or catching/rubbing/not tightened enough whenever I take a step. Please note that in the video, the noise is slightly before I heel strike. Maybe like the belt needs to be tightened? I feel like the slatbelt should be smoother than this... Should I contact support?

UPDATE:
Firstly, thank you everyone for all the advice. I thought I’d give an update because I’ve done a lot more testing today.
I did not keep repeatedly testing it. I only did one more controlled test to try and narrow the fault down.
Here’s what happened:
The treadmill powers up completely normally.
I left it switched on for a few minutes and nothing happened. No burning smell, no tripping, no issues.
I then pressed Start (with nobody on the treadmill) and the instant I pressed it, there was a large flash from inside the front of the treadmill. It lit up the wall behind it.
At exactly the same time there was a strong burning electrical smell (like a burnt hairdryer/electrical insulation).
The treadmill died instantly and tripped the same breakers again (B32 sockets breaker in the outhouse, B32 sockets breaker in the house, and the house RCD).
After that I unplugged it immediately and I’m not plugging it in again.
Since yesterday I’ve also:
Opened the motor hood.
Visually inspected the controller board, drive motor, incline motor and wiring.
Checked the plug and fuse.
I can’t see any obvious burn marks, melted wires or loose connections.
One thing I noticed is that the fault doesn’t happen just by switching the treadmill on. It only happens when the treadmill actually tries to run.
At this point I’m fairly confident the problem is inside the treadmill, not my house electrics.
Does this sound more like:
a motor controller board failure,
a drive motor fault,
wiring,
or something else?
Also, if anyone has had a similar fault on a Horizon T4000 Premier, I’d really appreciate hearing what the cause turned out to be.
Thanks again for all the help! I’m definitely not plugging it in again until it’s repaired because that flash was enough to convince me! 😂

Hi everyone,
I’m hoping someone can point me in the right direction because I’m completely stumped.
I recently bought a second-hand Horizon T4000 Premier. The seller said it had only been sitting unused for around a month before I collected it and that it had previously been used in their house.
Today we set it up in my garden outhouse.
The treadmill is plugged directly into a standard UK wall socket (no extension lead). The treadmill label says:
220–240V
7A
50Hz
My outhouse has its own consumer unit with a 32A socket circuit and 30mA RCD, and it’s supplied from the house consumer unit via an outdoor cable. The house also has RCD protection.
Here’s exactly what happened:
The treadmill powered on normally.
It ran perfectly for about 5 minutes.
We walked/ran on it without any issues.
The incline went up without any problems.
When we lowered the incline, it got down to about 4%, then everything tripped.
The outhouse lost power and the house RCD also tripped, so I had to reset both.
My sister said she saw a small flash at the socket when it happened.
We noticed a slight burning smell, but there was no smoke.
There are no burn marks or melting on the socket or the treadmill plug, and everything else in the house and outhouse has worked perfectly since resetting the breakers.
There were other things switched on in the outhouse (computer, monitors, lights), but they were all working from the other side of the double socket.
I’ve attached photos of:
House consumer unit.
Outhouse consumer unit.
Socket.
Plug.
Treadmill rating plate.
I’ve also seen a Reddit post where another Horizon treadmill tripped RCD/GFCI protection, but that person’s treadmill tripped almost immediately, whereas mine only tripped while lowering the incline.
My questions are:
Does this sound more like a treadmill fault (possibly incline motor/controller/wiring)?
Could this simply be an RCD compatibility issue?
Has anyone experienced this on a Horizon treadmill before?
Would you be looking at the treadmill first or the house electrics?
Any advice would be massively appreciated because I don’t really want to keep testing it until I know what I’m dealing with.
Thanks!

Hey everyone,

I've got a treadmill that's developed a squeaking/chirping noise whenever weight/load is applied while walking or running (it's much quieter or silent when the belt runs empty, no one on it).

Troubleshooting so far:

Pulled the deck cover and inspected the front and rear rollers.

Replaced the bearings on both rollers, thinking worn bearings were the culprit.

Reassembled everything, retested… and the squeak is still there, seemingly identical to before.

I've attached a video with audio so you can hear exactly what it sounds like.

Update: I was able to reproduce the sound by trying to stop the treadmill with my body weight while it was running, with little to no belt movement, after slightly reducing the belt tension. I weigh 82 kg / 181 lb, and the machine is rated for up to 120 kg / 265 lb, so I'm well within the weight limit. I'm showing this in the video. Chirp noise only when stopping the belt under load.

Treadmill just started making this sound halfway through my workout. I added lubricant, but it doesn’t seem to make a difference. The frequency of the clicks increases with speed. Any ideas?

10 year old, well maintained f63 sole treadmill. I tried to lubricate belt, adjust tension, and adjust speed sensor since this is often recommended for troubleshooting.

Thoughts on cause? If you had to try replacing something, what would you try? These components (motor, board) are not cheap so trial and error will exceed cost of a new treadmill after a few wrong guesses :(.

In video, I can see a green LED on the board light up when I step on the belt. After a while, it seems to fault, shutting down the motor. The LS1 fault display shows up about 3 seconds later when it notices it is not moving.

Thanks!

The cable is right underneath it but it doesnt fit under my bed. Is this bad for the cable?

Hello, For those who have the same unit, is it normal for the treadmill to make this sound when inclining?

I recently got given a treadmill and noticed when walking on it, it seems to jolt / slip slightly. It’s not too bad when walking but noticeable when running. I’ve followed advice and lubricated and also adjusted the back bolts for the tightness of the belt.

It does seem to make a random noise that sounds like the belt is rubbing. I’ve attached a video of said noise. Any advice would be appreciated as I’m desperate for this to work. Thank you

So today I got this email saying I need to throw this thing out. It is real as I've logged into Amazon and it does show up as needing to confirm I've thrown it out to get a refund. Did I get lucky that it didn't burst into flames? Should I buy a new one or just walk outside?
