Question about Hitachi EC89 4 Gallon Twin Stack Air Compressor
Several things to check. Amp draw to be within number on plate, if amp draw not correct check capacitor, should be within 5% of rating on cap.. If amp draw about right and cap reads good suspect faulty breaker. If amp draw high and cap. good check for leak at in-tank check valve. With pressure in tank remove hose at check valve spray soapy water. If check valve good, suspect reed valves leaking. If reeds are leaking the compressor will take longer than normal to fill and the discharge tube/air will get very hot. It is recommended to note the amount of time it takes to fill tank when unit is new and compare this as unit wears. Length of time to fill is an indication of how well unit is working. A combination of leaky valves and leaking fittings as well as leaking checkvalve will cause motor to overheat.

Testimonial: "best explanation I could have hoped for"
Same thing happened to my EC89....Unit would come on fine for 10-15 seconds then the reset button would trip! motor compressed air fine and all else worked great. But I Would have to stop working, walk back over to the compressor and reset the protection overload button on the compressor. It got "VERY ANNOYING" to say the least!! I ended up bypassing the reset button (I took the two wires off the back of the reset button and put them together) Unit worked great after that! so I ordered a new reset button for $8.00 and re installed it once it came in...WORKS GREAT NOW....I did not want to just eliminate the reset button permanently because if there was ever another issue with the compressor ( low oil, bad piston ring,low amp draw, etc.) it would burn up the motor vrs tripping the thermal protection button.....I do not suggest running it full time without the thermal protection button....but only to test for a bad reset button! hopes this helps someone with the same "reset button trip" issue.....
