Question about Hitachi EC12 Portable Electric 2hp Air Compressor, Oil Lubricated

1 Answer

Hitachi EC12 AC is "dead"

This AC "died" suddenly. It is as if it is not plugged in, however it is. No response to switch. Dead, dead, dead.
Appreciate any advice. Thanks.

    Good idea regarding diagnosis. Checked all continuity and all OK. Looking at capacitor(s). Thanks for advice.

    Hitachi EC 12 only used about 10 hours, looks brand new, took it to Hitachi service center and the service center said the motor was shot, and did not know what else was wrong with it until they got a motor. They thought that Hitachi would pay for any work that had to be done since it was like brand new. Then they said that Hitachi would not pay under them under any kind of warranty. So now it is in parts, took it too another Hitachi service center after speaking to Hitachi's Mr. Demetri, who advised me to take it there, since Demetri does lots of business with them. Now, this service center and Demetri are complaining that it is not put together in order to test. I explained to Hitachi's Mr. Demetri about three times that I am being told by both service centers that they cannot put the machine back together, since it is against the law. I told Hitachi's Mr. Demetri that Hitachi should help me out, since the machine has not performed as a machine. Hitachi's Mr. Demetri said that he would not do anything to help me out as in a "good faith effort" in order for me to be willing to ever purchase another Hitachi compressor. Any ideas, since Hitachi has wasted my time with their run around non solution.

You should take the cover off where the pressure switch is (the on off switch) and see if any wires fell off the connectors. the white wire should go straight throu to the motor, then the black wire will go to the switch than the pressure switch then to the motor. if you are careful enough you could temperarly straight wire the black wire from the cord to the motor wire.

Hitachi EC 12 2hp Air Compressor. Just get a buzz sound when plugged directly into 120v wall outlet. Piston and shaft turn freely. Have installed a new pressure switch. Just turned the compressor on...


Hitachi EC12 Air Compressor Parts : MASTERTOOLREPAIR.COM

Here is a site that says:
1. Are the capacitors good? (They get the motor going).
2. If they are, replace the stator, ($245)

If you don't find a good solution there, I would try taking it to a local motor rebuilder.

My Hitachi EC12 builds pressure, shuts off, then air escapes


I have the same compressor with the same problem. I have temporarily eliminated the thermal reset with a piece of 12 gauge hard wire and it runs just fine. However, I do want to replace it before the warm weather come to the north. I tested the draw at 15.5 amps and the reset was a 17 amp. I am told by someone with superior electrical background that I need to install a 20 amp thermal reset in it's place. I have found that mine runs best when plugged directly into a 20 amp circuit and when using an extention cord I have a 10 guage cord that will carry the load needed to run the EC12. I have also changed to 100% synthetic oil.

Hitachi EC12 plug it in and nothing happens. No noises....nothing. There is oil in the compressor and pump is moving freely.


Sure the outlet you plugged into is working, do not use an extension cord.

If there is power, then there is a black box, where the cord enters the unit., in here is the pressure switch, it tells the unit to work,
unplug the unit open it and see if the plate with the spring moves freely
and then try it again, if not you probably need a new one, I would contact
the company and see if there are problems with the unit and see what they will do for repair, or they might have a better option for troubleshooting this unit.

Dead laptop


Check the ac adapter is the proper one for that laptop. Check the power jack is not damaged or loose. let laptop site without battery or power for a few hours. remove battery and retry power. try another ac adapter if that doesn't work, you may have a reset button but not likely to solve the problem. sounds like motherboard is damaged, or something blew.
