I pluged up my aircompressor and one side off the plug melted.

Yikes!!! That's not good.

Sounds like you've got a ground fault somewhere and the circuit pulls so much amps before the breaker pops that the heat generated melts metal!

Get the compressor to an electrical repair shop or call in an electrician. Don't plug it it again until you find the fault and get it repaired.

Good luck,

Bill

Plug Melted - American Reality
by: Bill

It's not to get an electrician to change the plug, most anyone can do that. It's getting an electrician or compressor repair shop to find out what's shorting out on the compressor.

Yes, depending on the compressor, the fix might be worth more than a new one, but not fixing it might be a deadly mistake.

In Chicago, and I do not think I saw "an electrician" shop anywhere, but there are plenty of small shops, which would charge likely $$ - $$$ for a repair.

Getting a new compressor would be cheaper than having the $0.75 (ebay price) plug replaced by the electrician.

This is the American reality.

Fatal error with extension cord?

by Monica
(Springfield Illinois)

I used my son-in-laws small air compressor with a very long extension cord to fill a backyard blow up ring pool. It worked but air leaked out and when I went to refill, the air compressor was making quite a racket and had no air pressure but was still running. I then used my large capacity more powerful unit and of course still had to use the extension cord. The compressor cranked up blew air for a couple of minutes, rattled and completely quit running. Zero pressure, no motor sounds. What did I do and can it be fixed?

Can it be fixed? Sure, anything can be if you are willing to throw enough money at it.

One of the by products of too low power flow to an electrical motor is that it gets very hot. Many electrical motors have a thermal cut out that stops the motor before the temperatures reach a critical level.

Some of the thermal reset buttons are automatic, some are manual. Check the motor on yours to see if there is a reset button and if so, give that a push to see if that makes any difference.

The nice thing about a too long air line is that even if the pressure getting through to the air tool is too low to run it properly, the air tool won't be damaged.

The same cannot be said for a too long extension cord and an electrical tool or electrical motor.

If the reset button doesn't work, I would take the motor to an electric motor rebuild shop to have it checked out.

Good luck,

Bill

My compressor shorts out when I try to start it

Hi Dorothy. When you say the compressor shorts out, do you mean that something happens at the compressor and the fuse or breaker pops?

If the compressor is shorting then being near it when that happens isn't good. If it's popping the breaker though, it may not be shorting necessarily.

Could you please dump all the air from the tank and then try to start it again?

Please post results as a comment here.

Thanks,

Bill
