We just bought an air compressor that was used in a tool show and brought it home only to find that we couldn't get it to start. We plugged it in and it makes a sound for a few seconds and then turns itself off. What could be the problem? Are we doing something wrong? Yes it has oil and we have checked online for all the necessary things to do before start up. (We couldn't get an owners manual, unfortunately) but Rona has almost the same machine so we were able to get a copy of theirs. It still doesn't work. What could be the problem? Any ideas?

Re: new machine fails to start
A 2 hp electric motor needs usually needs a 20 amp circuit to run it. If you are attempting to run in on an extension cord, this will act up as well. Put the plug directly in an outlet and see what happens. You may have even tripped the circuit breaker on the unit.. it's on the side of the electric motor... just press it back in. Most of the household electrical circuits are 15amp circuits. so the problem may still persist. But if you get enough amperage to the unit, it should work fine...let me know what you find out.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

most likely a start run capacitor has failed
do not remove any pins of a plug as they are all need for electricity
if the capacitor replacement makes no difference , get in an electrician to test the machine and insulation
it is a replaceable part -if available-- but they are very seldom faulty
as you have not described a symptom of what brought you to that conclusion it is difficult to help you
As an indication of a problem, if the motor refuses to start, hums or does nothing , the most likely problem will be the start/run capacitor as they fail on a regular basis so check it for leaks , expanded case etc
Have you lubricated either nail gun? If not, go to Home Depot and get a bottle of air tool oil. It's in tools by the compressors. Disconnect the air hose from the tool. Pour about a teaspoon of oil into the air inlet of the tool. Reconnect everything and try it 10-20 times with no nails in the tool. Then try it with nails. Good luck.
Portables are priced to replace and not repair unless you are an HVAC tech with your own tools and supplies. There is no guarantee you could even get the imported parts. I recommend you replace the machine; make sure you check with local authorities regarding disposing of a used air conditioner that may contain refrigerant.
if there is enough air pressure present in the compressor the motor will stop,the pressure switch is working.if there is a good pressure at start then suddenly lost the pressure,there is no maintaining pressure to use but on the pressure gauge appear to be have a good or enough air pressure.
check if the pressure gauge have enough air pressure the motor is stop,meaning the cut out limit
switch stop the motor,if you loosen the air pressure from the valve until the cut in pressure attain or meet
the motor will run again there will be a cycle process
of differential pressure of cut in and cut out set up on pressure switch.
checking the compressor,be sure there is a high pressure on compressor and the compressor motor is stop,shut off service valve and disconnect unit device / tools from the service valve. if the compressor have enough air pressure crakc down the service valve and observe the pressure until it run again the compressor motor,if the pressure maintain the pressure you need to clean the bench, the problem is the unit device/tool you use is defective, but if the maintaining air pressure in the compressor is lost due to malfuction of motor and the compressor engine. check the pressure switch, check the motor function by loosening the belt and run the motor w/o the compressor engine if it is tripping brought it to service center, check also the lubricant oil,if neccessary change oil.have a nice day and fix my rate thanks a lot.
Good day, I don't understand your caption..........

However, it sounds as if the compressor is trying to start and cannot.
If the machine is under 5 years of age, the compressor is under factory warranty.
There is a relay, capacitor, and overload which are connected to the side of the compressor after removing the back bottom rear cover.
These items could be removed and taken to an appliance parts house, where they would be glad to test them for you. Replace failed parts.
However, if it is under 5 years of age, I would recommend you call for factory warranty service. They may have to charge you for one of these parts, but since it could be a failed compressor, and not the starting components it is better to let them service it and maintain the balance of your compressor warranty.
This sounds like one of the O-rings has failed. Yes it can be fixed. Check to see if HD has an O-ring kit for these guns. That kit will contain all of the O-rings as well as the lubricants for a total rebuild. That should resolve your problem.
