Did you want to know why my air compressor keeps tripping the breaker? Have your breaker got tripped? It is the most frequently asked question why does my air compressor keep tripping the breaker.

An Air compressor may trip the breaker for a variety of reasons. Additionally, there are several forms of solutions for each element that impacts the air compressor.

Electrical barriers on air compressors safeguard the engine and air pump. If there is a problem with the air compressor unit, the unit normally shuts off and stops the job.

Once the pressure hits the trimmed point, an electrical current will pass via the control valve, the machine to start the loop, and a start buffer to jump-start the unit.

A fuse box is an electrical switch used to guard against overloads that might harm an electrical circuit. Its role is to identify faults and stop the flow of electricity, to put it simply.

Contactors shut off the air pump system and halt operations when they trip. The wrapping on the wire that connects The air compressor to the circuit might be harmed.

The pressure regulator will respond to this reduction in tank pressure when the air compressor container is emptied towards the cut-in level.

When the compressor pressure exceeds its cut-out pressure, the pressure switch trips to passing, allowing the compressor to begin and continue.

Reasons for tripping the breaker

There are many things more annoying than attempting to use the air compressor and having circuit breaker overload, especially if it keeps happening.

It becomes worse since there are various potential reasons, many of which are hard to identify. Therefore, the numerous causes air compressor could be triggering the circuit breaker.

  • Scratched or Shorted Cable

It might result from animal bites, such as those from mice, or just age. If this occurs, it might short if it unintentionally makes touch with other wires.

Beginning at the detach switch and moving toward the circuit breaker board, should inspect the air compressor’s cord. If it comes across a broken wire, it should fix it by utilizing wire and termination connections.

When switching on an air compressor, if the breaker trips during startup or lamps briefly dip or oscillate, it has significant power consumption.

The circuit breaker can trip if this high power consumption exceeds its capability. Installing a difficult start kit with a switch and a fast starting resistor is the best solution to this issue. It can reduce the amp needed for each starting by approximately 50%.

  •  Blocked Condenser Loop

Excessively grit in the breath path to the air pump will force the blade to operate harder, using more electricity and a water nozzle to spray water on the coil from within to wash it. Be cautious, though, since using too much pressure from the hose might harm the locks. 

Nitrogen levels might potentially cause circuit breaker tripping. Whenever the compressed air in the air compressor does not meet the product’s specifications, it may fail and set off tripping. It will keep using power and may surpass the breaker’s rating in terms of current, causing the circuit to fall.

  •  Dirty Air Filter

The motor may be overworked and draw more electricity than usual if the inlet filter on the compressor is blocked with debris and grit. The switch might trip if the additional power use is more than what it can handle. 

Ensure the appropriate quantity of oil is in the condenser if it is gasoline. Both and often, too little fat can make the pump strain and act electricity, which trips the circuit breaker. Similar to the condenser fan intake plate, if the motor overheats and the breaker trips, it might be due to debris clogging any airways.

  • Extension Cord

Extender cables and air compressors would not mix nicely. Since most extended lines aren’t designed to handle the current consumption of blower motors, the engine is weak.

It might lead to the engine overheating and tripping the circuit. A frayed extension cable is a fire risk and should be avoided. Extension cables are included with the electrically powered pumps, which enable it simple to plug into power.

The fuse box will trip in the event of an extending cord failure, shutting off the power and the inflator equipment.

In the same way, if multiple gadgets are plugged into a power switch, it may overload the circuit. The piston(s) will not be roaming smoothly if several of the motor valves have been corroded or clogged with dirt; it might cause burning or excessive power consumption. Motor-driven compressors are also susceptible to it, though.

  • Faulty Pressure Switch

Another potential reason the circuit trips when the pump resumes sustaining container capacity is broken pressure control.

The control valve notifies the motor to turn back on again and inject more gas into the container whenever the container is nearly empty.

The pressure device’s contact contacts might short circuit if damaged or loose, tripping the breaker. An air compressor’s stocker lever is an essential part.

Any pressure created into the air cylinder above the cylinder is released by the inlet port valve when the reservoir hits its volume threshold and the compressor shuts off.

If the valve is broken, air will persist and put more strain on the engine whenever it begins to keep the tank at capacity. The higher load may result in a rise in the current draw, tripping the circuit.

Fragments and Restoration Needed

First, examine the component to determine the source of the issue when an air compressor appears to have ceased functioning due to a damaged part.

The essential elements must not be damaged for a compressor to function. However, everything is replaceable:

1.Broken Air Compressor

All the connection locations on the funnel and any old repair valve won’t fix the issue. So, it may need to locate a shift that can fit several of the four or five connection points to solve the problem. Typically, it will entail connections for the fast connection, air station meter, pump tank, pressure regulator, and canister evaluation.

Before purchasing a new control valve and intake, pay attention to the information on the old control that must match through any modern switch that connects to the compressor:

  • Circuit count on a control valve and hose.
  • Strength of the initial compressor
  • Adjustments for the previous air switches trim and slashed.
  • Putting the stocker valve in place

2.Cracked On/Off Button

It might be a problem with the valve directly if the rotor of the electric fan won’t turn on when users turn the light, but users should do some trials first.

Ensure the electricity cable is connected to a working outlet by checking it. Connect a lamp or other electrical item into the socket to test whether it turns on while the power supply cannot turn the pump on.

If the connection operates for other appliances but not the compressors, peel the cover covering the switch, take out the plug, and look up the controller’s specifications in the compressor host’s handbook. Verify the new button will fit the outlet and meet the specifications.

3.Damaged Compressor Fan

Although polymer is less affordable than steel but more quickly vulnerable to damage and strain than metal, most modern air compressors push air with rotors plastics, especially on the bottom end of the price range.

As a result, users may use a broken set of plastic blowers as an excuse to switch to metal. Thankfully, a new fan from any substance will function in virtually any turbine.

Look up the compressor handbook’s component description and matching measurements before choosing a new fan.

If the initial fan cannot be located, check its height and opening size. Remember that the turbine and the circulation angle impact the compressor’s effectiveness and design.


Hopefully, after reading why does my air compressor keep tripping the breaker, customers might be able to know why my air compressor keeps tripping the breaker.

It has been explained thoroughly about the tripping of air compressors, and it has been described above about the possible reasons for the breaker tripping.

A lot of that must keep in mind while operating the air compressor that avoids tripping; turn off the air compressor when it is fully charged, but still, the indicator starts to drop as soon as the compressor is turned off.
