Question about Air Tools & Compressors

1 Answer

Air compressor trips motor breaker

John Deere A75 The breaker on the motor trips off when the unit calls for more air after the initial fill. The unit will begin to fill the tank and when filled, shuts down. When more air is required, the switch trips for more air, but the motor will try to start (it hums) and after a second or so trips the breaker. As long as the motor does not cycle off it continues to work fine. Just when it cycles off is when the problem occurs.

    hitachi air compressor ec119sa. Just hums when i turn it on and blows the onboard breaker,but if i turn it on and let it hum for just a sec and turn the switch off before it blows the breaker and i do this about 10 to 15 times it will finally run and fill the tank. once the tank is empty the breaker will blow again when it restarts.

Trips thermal overload. power source ok. oil ok


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.

Hitachi EC12 won't refill air after initial startup


hi there,
of course comparative cost buying and repairing make a cost reduction.if your compressor run smooth but tripping,make sure where on the right path of diagnosing of your compressor,we can check if the motor or compressor is shutting off the unit.disconnect the belt from pulley of the motor to compressor,run the motor if still tripping w/o load its better if you have calmp ammeter test,to check the current rating,if it is tripping motor is deffective replace the bearing.f motor is fine sr till tripping check the compressor also the crankcase bearing,replace worn out bearing.have a nice day dont forget to fix my rate.thanks a lot.

Electric Air compressor just hums then trips breaker.


usally there is a releaf valve that takes the pressure off the compressor while it is resting. If that pressure is not off when the drive piston starts the motor will overload and blow the the breaker or reset. Check for a releaf valve for when the unit has reached full pressure
