Compressor Kicks on Kicks Breaker When It Kicks on Again
There are 2 reasons an air compressor can trip a breaker,
electrical and mechanical.
Most usually, the motor is pulling likewise much amperage but before diving into the electric circuit. Inspect for mechanical issues, such equally the pump being strong or locked upwardly. Inspect bleeder or loader valve. I see this occasionally, I hate myself when I spend two hours testing circuits, and it should take been a fifteen-minute job replacing a bleed-off valve.
Safe offset: safety glasses unplug the compressor.
Visually inspect the compressor and surrounding surface area for obstructions to the mechanical parts of the compressor, such as pulleys, belts, pump, and the motor.
Earlier You Tin Repair Your Breaker business, let us save you some time by asking a few qualifying questions.
This is the first time plugging in this compressor, and the breaker tripped while running?
a) my compressor is new
b) my compressor is not new
my new air compressor trips breaker
The most common reason I discover circuit breakers tripping with new compressors is too much load from combined amperage draw from multiple devices and tools on 1 circuit.
Sometimes on new compressors, the easiest way to cure this concern would be to move the compressor to a dedicated excursion large plenty to handle the load. Moving the compressor may also identify a week breaker. If the breaker trips on one 15 amp breaker merely not the other, The tripped i may exist old and worn.
I would recommend replacing that worn breaker and move the compressor back to its original location.
STILL, TRIPPING BREAKER?
Your air compressor is tripping the breaker due to untenable current demands that exceed the breaker's capacity. Several factors tin can cause your compressor to pull too much ability, but we will not waste time testing the compressor. If we determine it is the compressor, It's new; bring it back.
Earlier resetting the breaker, find the amp rating on the compressor, be certain that the breaker is large enough to handle all the appliances and tools on that circuit. Take this time to unplug all other devices or tools that may be causing a describe on that circuit.
Inspect the outlet that the compressor is at present using. Is it lose, or has any signs of overheating? Replace the outlet or repair before going on to the adjacent step.
How to test an unloader valve on an air compressor
To see if a failed unloader valve is the root of the problem, accept the following steps:
- Unplug your air compressor
- Open the tank drain and let all pressurized air escape out of the tank
- Plug the air compressor back in
- Plough the air compressor switch to "ON," restarting your air compressor. If the compressor starts, let the system make full.
- if the compressor still will not start inspect the pump.
- In one case the compressor turns off, bleed some air until the motor starts. Replace the valve if the breaker trips while attempting to turn on with a full tank. The cause was the valve not releasing pressure from the cylinder head.
Inspecting an air compressors pump for mechanical concerns
To run across if a failed pump is the root of the problem, take the following steps:
- unplug the compressor
- remove the cover plate or belt guard
- plough the pump by hand it should spin freely
If the pump is locked or hard to turn, It time to replace the pump
If the pump turns freely its time to test the electric circuit.
Disclaimer: Self-diagnosing air compressor concerns may not be a elementary problem. If you are not familiar with electric motors or circuitry, then y'all may need to accept your air compressor into a shop to have a load test performed and diagnosed. Performing electrical tests is chancy and should just be performed by a professional.
Measuring the amps that your air compressor produces while in use can be washed ane of three ways at the billow box, exposing the wires at the compressor or using a splitter between the outlet and the cord of the compressor.
Click the link below to skip you downwards the page that best fits your situation:
My compressor is:
- 110volt AC
- 220volt unmarried-phase or 220volt 3-phase
How to Measure amperage on an air compressor. 110-volt A/C
Note: The compressor should be almost full of air to stand for a heavier load on the motor on start and run.
plugging in a splitter into the outlet then plugging the compressor's cord into the splitter is much like using an extension string is the easiest way to test amperage.

- measuring the amperage at the breaker box,
Rubber glasses! Open the billow box and turn off the main breaker,
reset the breaker to the compressor and then close it off, remove the console to betrayal the wires and breakers
place amp meter effectually the load wire, let some air out of the compressor so when you flip the breaker, the compressor turns on.
Watch the meter at start-upward and while running.
Was the amperage on start-up and running lower than that of the manufacturer specifications?
ii.measuring the amperage draw with an outlet splitter or inline wattage meter. If You have this splitter, it makes life a whole lot simpler. Unplug the air compressor, plug the splitter into the wall plug in the compressor to the splitter. Clip your meter on the splitter. Y'all are ready to start the air compressor. measure the amps at start-upward and while running
Was the amperage on get-go-up and running lower than that of the manufacturer specifications?
3.Measuring the amperage draw on the air compressor is my terminal option. The only reason I sometimes mensurate amperage this way is I suspect the capacitor, and a quick visual inspection may reveal it needs replacing. All air compressors are different, and the manufacturer uses equally footling wire every bit possible, making it sometimes challenging to expose and separate wires. Once y'all accept gotten a location to clamp the meter. Start the compressor and lookout man the amps at kickoff-up and while running.
Was the amperage on start-up and running lower than that of the manufacturer specifications?
How to measure amperage on an air compressor. 220-volt A/C
Safe commencement! Unplug or turn off the breaker, examination to make sure power is off. Inspect all wire connections on the compressor. Removing cover plates to expose the wires will provide a place to use your amp meter.
I always recommend measuring 220 Amperage at the Billow box. All connections, including the ones at the breaker, need an inspection.
Note: The compressor should be almost full of air to represent a heavier load on the motor on start and run.
220-volt has one mutual or neutral lead and two load wires measuring 110 volts. It is besides possible information technology will have a basis wire. Place the amp meter around one of the two load wires. Offset the compressor and let information technology run until information technology shuts off.
Notation the amperage. Motility your meter to the second load wire.
Drain air from the system until the compressor starts and repeat the procedure.
If you are dealing with a new compressor and producing more amps than the manufacturer's specifications, render it to the store. Brandnew compressor failure is more mutual than yous would recollect.
Was the amperage on start-up and running lower than that of the manufacturer specifications?
(aye)If you Verified that the amperage draw is lower than the factory specifications and that of the breaker. The tripped breaker may be erstwhile and worn. Is information technology Possible to move the compressor to some other circuit with the aforementioned amperage rating? Cycle the compressor on that excursion if there is no problem with that breaker. I would recommend replacing the worn billow.
(no) A faulty capacitor is the most common cause for compressor tripping a breaker. Some compressors accept two capacitors, and some have just one.
How to test an air compressor capacitor. with video
Rubber First: Habiliment safety glasses disconnect power, and make certain power is not nowadays.
Remove the encompass to the capacitors. One capacitor will be the first capacitor. The other will be the run capacitor. Ratings and percentages are printed on the side of all capacitors. If it is not legible, there volition exist no mode to test the capacitor. I usually supercede capacitors that look distorted in whatsoever way, and capacitors are cheap enough that the toll is negligible compared to labor or a comeback.

Circumspection: A Capacitor tin can store a deadly D/C discharge!
With an isolated Scew driver, touch the top leads together on the capacitors. Discharging them eliminates the chance for shock.
Now that it is safety to handle the capacitors, remove them and look at the side of the capacitor; take note of the micro-farad range. The format will read something like(540-630µf) or (64µf + – six%) but not those exact numbers, and This micro-farad range is the tolerance the motor needs to start and run under random loads generated by the compressor. In the showtime example (540-630µf), when testing the capacitors, the micro-farad range should autumn between those readings. In the 2d example (64µf + – 6%), you must first do some math. 64×0.06=3.84 round upward to the side by side highest circular number equals 4.0 64 minus four equals lx and 64 plus four equals 68
in this example, the capacitors range is between 60µf and 68µf.
Set your meter to this symbol -)|- or the µf. Connect the leads and measure the micro-farads. If the reading falls betwixt the variance, the capacitor is good. In this example, the reading reads 61.2 µf the capacitor is within tolerance. And we would movement on to the adjacent step or the next capacitor. Replace the capacitor if it is out of range.
Pro tip: The Start capacitor volition have a larger farad value and volition sometimes have a plastic cover.
Is your air compressor the cause of your breaker tripping#weakbreaker
If you plugged the compressor into another outlet and the breaker did non trip, or you measured the amperage draw during use and the beakers ratings are in a higher place that witch the compressor is drawing, chances are the billow is weak or there is a loose wire in that circuit. audit the excursion for loose wires and replace the weak breaker.
