Others Yong Heng new out of box shooting sparks

I ordered a Yong Heng (with auto shutoff) through Amazon and when it arrived well packaged and it has all the right information on it to imply that it is not a clone/knockoff. However, after confirming the specs on the name plate and following all of the steps from the manual for commissioning it, when I flip the power switch it shoots sparks out the rear of the compressor and trips the GFI outlet. This same outlet powers my drill press without issue so I am fairly confident it is not contributing to the issue, however, I also moved the compressor to a non-GFI outlet and tried there with the same results of the compressor shooting sparks when the power switch is flipped.

I pulled the cover off, and cannot find any thing obviously charred but I did find what looks like a ground wire that was cut off from the wire loom as well as seeing that the capacitor is floating inside the case and what looks like it may have been the mount point for it has been sawed off.

I was curious to see if anyone else has experienced this behavior from a Yong Heng compressor, or if anyone has had decent luck with any particular seller on Amazon for one?

These compressors pull 1800 Watts which is 15 amps. You need a dedicated circuit with no other load on it except the compressor. You also should have that circuit on a 20 amp circuit breaker and also your outlet should be rated for 20 amps. Most outlets are rated for 15 amps before they overheat and maybe melt..
At least with Amazon you can return it for refund or replacement.
I have 3 of these compressors and the only flaw with mine is the main on-off switch burns out. Exact replacement switch is $2.

What you are describing sounds like it has an internal electrical short and the compressor needs to be returned or replaced.

Amazon can perform exchanges, I have done this without issue.

Just tried it on a dedicated 20A plug (nothing else on it) and something in the compressor is still blowing sparks when the power is switched on, I will try pulling the cover off again as soon as I am off work and see if maybe there is some evidence of where the short is occurring. I would really like to get this thing working but am not a fan of a "new" device that has an obvious electrical issue.

It is unfortunate as I have heard great things about them, I will probably try to see if I can order another one from a different seller on Amazon and hope that it works.

Thanks for the info.

@robertwalsh1981 I suggest that you put that thing in a box with a return label and make sure it’s on a brown truck tomorrow if the roadways in you area are clear.

Some guys ended up being able to keep the bad compressor for parts. Dunno how they worked that out.

Yeah, it is going back. Unfortunately the seller doesn't offer exchanges, so once the refund makes it back I will be ordering another one and hoping it does better.
 
Im still surprised nobody has died from using one of these ticking time bombs. Respectfully I'd ask how much it's worth to feel safe having one of these inside your home?
another reason why I just saved the money and grabbed the Alkin
and if yo think you can't do it I promise you can.
I planted a extra 12 rows of okra and covered the cost. think you can always do to make extra money.

I am looking at the Alkin, I suspect that will be the endgame for my setup, but convincing my wife that I NEED to spend another ~$4k right after having spent ~$3k purchasing the gun, pellets, and accessories is going to be a challenge :D But give me a year or two and either the memory of the initial expenditures will have faded enough or a couple of family members who live on the same family ranch and are also getting into PCP shooting will be in a position to go in on it together.
 
I have what appears to be exactly the same compressor but it is branded "Titanium".
It works well and if you feed it nice cool water it will run for hours filling large bottles from empty. Mine is a 220V version so the current draw is half of what yours is.

It is important that when you start the compressor to have both pressure releases (one on each side) open so that the motor can start without a large surge in current. The moment it runs I close both releases and open the tank.

I have a replacement unit ordered and am hoping for much better results. Everything I have read so far indicates that if/when you get a decent unit they run well and do a great job filling guns and tanks. It should make for a decent stepping stone until I can consider something like an Alkin.

I hope your next one will be as great as mine, filled 2 x 6.8L bottles today from 190bar to 300bar, no problems and it did not take long.
