Yong Heng Problem..........

[Kraemer99]

Received new compressor and first start up all it did was buzz and then I think flipped the breaker on the power strip. Mine is a version without all the lines on it and the pressure gauge is at the top of the cylinder. 
Anyhow don’t see any reset button and have tried moving the fan at the rear. Any ideas as to trouble shooting?? Maybe I got a dud??

Update: Got it to run but at initial power up it buzzes and I rock the unit and it turns on. Seems hard to get started

Inductive load unable to acquire the surge current amperage in-rush to overcome the machine resistence. Move closer to a higher amperage power source or inspect the start capacitor on the motor.

Hope this helped!

I live in an old house. Kitchen does have what appears to be 20A outlets. Still very hard starting. Will this hard starting cause harm??

Who knows?

I pulled mine apart and soldered all the connections instead of using the twist caps.... Seemed to help make startup easier

Doesn't sound like an actual Yong Heng to me more like a Tuxing clone.

Doesn't have all of the lines may not be a good thing as it likely is missing the all important filter that removes moisture and oil from your air before it goes into your gun or tank.

Good advice from LMNOP they need about 18 amps at start up. The unit should not be harmed by a slow start up, so long as it is able to continue turning and start, and as it wears in it should start easier. From what I have seen and heard It is normal for them to start a bit hard when they are new.

I've got one just like it and found that I needed to have the shortest extension cord using 12 gage wire with nothing else on the circuit. I found as bio man said that after everything broke in it would start no problem. You are starting it with the air bleed screw open correct?

Thanks everyone for your help. I’m convinced that my problem is power. The outlets in this old house are original and are so wore out the plugs nearly fall out of the outlets. Hoping with all around better electrical connections that my unit can be broke in properly and starting won’t be an issue.

Definitely don't plug it into a power strip. Plug directly into the wall with no extensions. Mine was hard starting at first, but after break in and an oil change, it starts much easier. I also have 20a outlets in the kitchen.

Definitely, don't use a power strip. Also, make sure there is no back pressure when you start up and that all valves are open on the compressor.

Nothing wrong with a power strip in fact its a good idea to use one that has an on/off switch as it will keep you from forgetting to turn on your water pump and burning your compressor up like I tried to do several times.

Just make sure it is a decent quality unit good for an honest 15amps, more would be better, and with 12ga wire so you are not choking the amps it needs to start down.
