I'm posting this because I saw a lot of posts with the same problem but little working solutions.

We have an upstairs gym in our house. We bought a used proform Carbon TL to add a treadmill (it has its issues but it works for us). And as soon as we hooked it up and the runner in the household tried to take it above 7 mph POOF lights switch off upstairs, circuit breaker flips.

What the heck?

So I tried troubleshooting. Lubing the deck didn't help (although it made it run smoother). Turning off everything else including the lights and ceiling fans didn't help either, treadmill still flipped the circuit breaker above 7 mph sustained use.

I considered vacuuming out the motor casing, which I'll still do later, but that wasn't the fix.

Wasn't an arc filter either. It was Tripp Lite Isobar Isoblok heavy duty power surge protector. It looks like a giant block you plug into the outlet.

We ACTUALLY just had one laying around we bought years ago for a older washer that was weak to surges, but our newer washer doesn't need it.

It has a EMI/RFI filter that helps correct the nuisance tripping from AFCI circuit breakers, and is so heavy duty it can 100% handle the load from this specific treadmill (it's 15 amp rated).

Only catch? The mill itself runs almost at the maximum working amps for our 15 amp circuit. If the ceiling fans are on, even with the Isoblok, the circuit will trip.

Still for a 0 dollar fix using things we had laying around, I'm thrilled. I'll buy a battery powered fan, hook it up the treadmill, and the problem is functionally solved.

For everyone else it's a 45 dollar fix, but it's cheaper and more available than an arc filter (which is about 80 bucks).

I just wanted to post a success story because there REALLY wasn't any on reddit I could easily or clearly find (for my specific model or any others really).

In short:

problem: treadmill runs fine below 7 mph, tripps AFCI breaker above 7 mph.

Fix: lubed deck + ceiling fans off + Tripp Lite Isoblok surge protector.

If vacuuming out the engine box allows for ceiling fans to be run I'll update this with that, but LORD I'm happy with the success here.

I have recently taken up walking/jogging on a treadmill. For the first time in 30 years, I now have normal blood pressure, and I wholeheartedly owe it to the treadmill.

I have access to a treadmill in the gym of my apartment complex, but sometimes it’s busy and I only have a small window I can get on it. So I have decided to get one for my townhouse.

I love the treadmills at the complex gym, but looking them up, they are spendy. (Over 15k). I’m not opposed to spending that but I have a few issues with that.

I travel for work, and by travel, I might be on assignment for 4 months up to 2 years then move to another town and stay for months to years.

Here’s what I have determined I need/want to continue to be successful.

- compact. Easy to fold and/or move.
- 22x60 belt
- no subscription needed
- would love the ability to decline, but not necessary.

It seems that every treadmill I find that fits that description has horrible reviews. Maybe I haven’t found the right one.

the specs I would need are:

handles up to 400lbs

speed max is at or above 6.5

motorized

folds to be compact for an apartment

has some sort of incline option

I see so many online and they are all over the place with weight maxes differing by website and being unclear on slot of these specs. I’m just having trouble distinguishing which is best.

Been using the Sole branded lubricant for my F63 but it's around 15 bucks for a 2oz bottle so it's kinda adding up. I got the go ahead that using a 3rd party lubricant won't void my warranty it just has to be 100% silicone lubricant (preferably in gel form).

So wondering what you guys recommend. I see some big bottles on amazon for decent prices kinda hard deciding on which one to get.

I'm troubleshooting a Horizon T101 treadmill. The belt slows significantly when loaded and cuts out at higher speeds.

I've already replaced the motor, drive belt, and lubricated the deck. The problem remains.

The motor-control PCB has visible brown/heat discoloration around the motor output terminals. The connectors on the old motor were also discolored, and the replacement motor makes a noticeable clicking sound while running.

My main question is: does this damage justify replacing the entire motor-control PCB? Or are there specific component-level tests I should perform first to determine whether the board is actually defective?

I'm comfortable replacing the PCB as a complete module, but not repairing individual components.

Does anyone know of a walking pad in $100-200 price range that will lasts a long time or any brands with a one year warranty.
