Hi Sammy,
It sounds like there is a direct short on the circuit. Before going any further, check other outlets on this circuit and make sure they do not have anything plugged in that is not expected and does not work. Check OUTSIDE your home, basement, garage, etc. as these locations require GFI protection - and may be fed from the bathroom outlet. After removing devices that are plugged into the circuit, attempt a reset of the breaker once more.
It is not likely that the circuit breaker has failed (but is a possibility). The outlet in the bathroom is probably a GFI type. You can determine this if it has "Test" and "Reset" buttons on it. You should be able to press the Reset button in fully even with power off. After resetting, you can attempt the resetting the circuit breaker as you have described above. If it stays on, try pressing the "Test" button on the outlet. Doing so should trip power to the outlet (and causing the "Reset" button to pop out) but leave the circuit breaker "On". If the breaker also trips, the GFI outlet is suspect and might need to be replaced.
At this point, a qualified electrician should be consulted to locate and clear the wiring fault.

Air compresser comes up to pressure just fine but when demand call for it to kick on locks up. if you bleed it off to ) it will pump back up


if it's tripping the breaker it's pulling to many amps i have one that puulls 15 amps and you have to use 20 amp breaker.

How many 100 watt light bulbs can I hook to a 20 amp breaker (120 volts)


A 20 Amp breaker will support 2400 Watts with a 120 Volt line.

120 Volts times 20 Amps (Amperes) = 2400 Watts.

Answer? 24 100Watt light bulbs.

HOWEVER, you should always allow 1 cushion of 100 Watts.
That would be 23 100Watt light bulbs.

(Wait until you add electric motors to the equation. Things start getting a little more complicated)

(I always use 20 amp breakers for lighting. 15 amp breakers for lighting is phased out.

Secondly a 20 amp breaker requires using 12-2 or 12-3 wiring. (12/2, 12/3)
SO does the receptacles.
Therefore 12 gauge wiring is used throughout the house, until you come to the heavier loads )

[ 12/2 = 2 insulated conductors, and one bare copper ground wire.
12/3 = 3 insulated conductors, and one bare copper ground wire.

Remember, with 12/2 the Black wire is ALWAYS the Hot wire. White is Common (Neutral). Bare copper is Ground wire.

12/3 has 3 conducting wires.
One Black, one Red, and one White for the Common. (Neutral) Bare copper is Ground.
Used for 3-way switches ]

When cold compressor starts and fills up with air. after used with power tools, the compressor wont restart.


you may have a bad pressure switch:

Unplug the compressor. Drain the tank down to zero. Close the drain. Get down close to the pressure switch and have someone else plug the compressor back in while you are closely monitoring the pressure switch. Do you hear anything happen? Do you see any movement in the pressure switch.
by plugging it in with the tank at zero pressure, you should hear a click as the pressure switch trips due to low pressure. It should trip and send power to the electric motor. If this doesn't happen, you may have a pressure switch problem.

My d55141 air compressor was humming before it kick on now it does nothing


I HAVE HAD THE SAME PROBLEM WITH A SIMILAR DE WALT COMPRESSOR.
FIRST THING-GET AN ELECTRICAL TEST METER,MAKE SURE THE POWER SOURCE HAS MINIMUM 110 VOLTS,LOW VOLTAGE IS A PROBLEM ON CONSTRUCTION SITES,BEING AN ELECTRICIAN FOR 21 YEARS I HAVE WASTED A LOT OF TIME LOOKING FOR PROBLEMS WITH MACHINES AND POWER TOOLS AND DID NOT LOOK AT THE OBVIOUS.MANY TOOLS WILL NOT WORK WITH LESS THAN 100 VOLTS,AND CAN ALSO BE DAMAGED BY LOW VOLTAGE.
IF THE VOLTAGE IS 110 VOLTS UP TO 125 VOLTS,THE NEXT STEP IS LOCATE AND CHECK THE CAPACITORS,THERE SHOULD BE 2,ONE IS START,THE OTHER IS RUN.REMOVE THEM ONE AT THE TIME TAKING CARE TO MARK WHAT WIRE GO TO WHAT TERMINAL.WITH A DIGITAL TEST METER ON CONTINUITY,PUT ONE LEAD TO EACH TERMINAL ON THE CAPACITOR,THE READING SHOULD START COUNTING UP OR DOWN,IT DOES NOT MATTER WHICH WAY AS LONG AS IT KEEPS COUNTING,AFTER 30 SECONDS REVERSE THE LEADS TO THE OPPOSITE TERMINALS.THE READING SHOULD COUNT THE OPPOSITE WAY FROM THE FIRST READING,WATCH FOR 30 SECONDS.
IF YOU GET READINGS BOTH WAYS,THE CAPACITOR IS GOOD.INSTALL IT BACK ON THE MACHINE.
IF YOU GET NO READING OR JUST ONE WAY,THE CAPACITOR IS BAD AND MUST BE REPLACED.
REPEAT THE PROCESS ON THE OTHER CAPACITOR,REPLACE IF NEEDED.
THESE STEPS SHOULD SHOULD GET YOU UP AND RUNNING,BUT I HOPE IT IS JUST A SIMPLE LOW VOLTAGE PROBLEM.
LOW VOLTAGE PROBLEMS ARE CAUSED BY VERY LONG EXTENSION CORDS,OR WEAK BREAKERS.
IN THIS NEXT STEP,BE VERY CAREFUL,GETTING ENERGIZED COULD INJURE OR KILL YOU.
IF YOU ARE NOT COMFORTABLE WITH THIS,CALL AN ELECTRICIAN.
A GOOD INDICATION OF PROBLEMS IN THE NEXT CHECK OUT IS OTHER OUTLETS HAVING LOW VOLTAGE,MEANING MULTIBLE CIRCUITS

TO CHECK BREAKERS,REMOVE THE PANEL COVER OF THE POWER SOURCE FEEDING THE OUTLET YOU ARE PLUGED INTO.
WITH A DIGITAL METER,PUT THE BLACK LEAD TO GROUND,AND WITH ALL BREAKERS ON, TAKE THE RED LEAD AND GO TO THE SCREW HOLDING THE WIRE IN EACH 15 OR 20 AMP BREAKER TO VERIFY 110 MINIMUM VOLTS AT EACH BREAKER.
IF YOU FIND ONE BREAKER WITH LESS THAN 110 VOLTS,REPLACE IT.
IF YOU FIND EVERY OTHER BREAKER WITH LESS THAN 110 VOLTS GOING DOWN EACH SIDE,YOU HAVE MAIN POWER ISSUES AND SHOULD CALL A QUALIFIED ELECTRICIAN.
BEST OF LUCK....

Motor kicks on , hums and then trips breaker


Thank you for posting your question here on Fixya.com.

The motor is likely failing. It may be a small part such as the capacitor or the starting switch, but could also be more severe such as the winding itself. You will also want to examine the shaft to see if it is damaged, best, or the bearings seized.

If you are not familiar with testing these parts your best bet would be a local electric motor repair shop to see if the motor can be repaired or if it would need to be replaced. They should also be able to ensure there is no pump damage.

If this answer does not fix your problem, please comment with additional details prior to rating the answer. Positive feedback is appreciated once your problem is solved!

Mind does not turn on. sounds like the motor got stuck.


Is it cold out?? Empty the tank of air, hook it up to a receptacle, not a cord, then try it. Mine has to be warm or empty, no cord unless it is 20 amp breaker, the starter motors on these things draw 16 amps, and a 15 amp breaker won't do it, and a cord loses too many amps. Once it warms up it is fine. Try it.

Oil free rigid air compressor will not get above 90 psi and keeps running


THESE HAVE TWO COMMON PROBLEMS. FIRST IS THE SMALL LINE FROM THE COMPRESSOR TO THE CHECK VALVE ON THE TANK LEAKING. OFTEN IT IS DAMAGED WHEN THROWING THE THINK IN THE TRUCK. THE OTHER PROBLEM IS THE TEFLON SEALING RING ON THE PISTON. AFTER SO MUCH USE IT SIMPLY WEARS OUT AND MUST BE REPLACED. I THINK IT IS A PISTON/ROD/SEAL RING ASSEMBLY, ALL ONE PIECE.

Have rigid twin stack air compressor. Only keeps about 75 psi and keeps running. I do hear air from the exhaust port (seems normal). Haven't used it for a while. Any ideas? Thanks, in advance.


possiably the " reed valves under the head are not closeing off all the way. These may be bent or somehow distorted their tension most of the time from exsesive heat. Good luck
