SOURCE: compressor will not shut off

My emglo electric air compressor will not shut off when it reaches 90psi that I set it for and it keeps going so I have to shut it off manually because I am afraid it will blow up if I don't shut it off . The switch works manually,;what is stoping it from working automatically to the pressure I set it at? Model # AM78HC4V

SOURCE: emglo airmate AM78HC4V; when trying to start

I had the same problem. Replace the motor capacitor. small white cilinder part with two wire plugs conected to it. This will have a single bolt holding it to the frame casing, you will find it under the black plastic shroud that covers the motor. Take it into any electrical or compressor shop and they will check it for you. costs about $35.00.

SOURCE: Have emglo airmate when I turn it on the overload

It could be a couple of things. To me it sounds like you have a short in the motor or damage to the cylinder and piston. You need special equipment in order to test the armature and field for a short. There may also be damage to the brushes and brush holder. There could also be a problem with the cylinder and piston. The bearing could be bad causing a hard start for the motor. I think it could be the combination of the two problems listed above. You may want to check the pump first and if that is not the problem it is an electrical short in your motor in which case you should buy a new compressor. It will cost more to fix if the motor is damage than to buy a new one. "BER" Beyond Economical Repair.

Can i substitute common motor oil for the proprietary oil sold for my AM78 Emglo 2-tank air compressor?


Dewalt claims that motor oil will cause carbon deposits to form on piston/cylinder head and on the inside of the discharge tube. I see carbon deposits on most all compressors that come in for repair. The carbon is not reason for repair. Usually forgot to add any oil causing rod failure. I believe that most compressor oils are just mineral oil. If the climate in your area is moderate, and you do not use the unit for 8 hours a day, motor oil will work just fine. The crank is steel and the piston rod is made of aluminum (no bearing shell). What makes the unit last longer is change the oil more often (holds very little oil). Good luck
