If the capacitor of the motor of your air compressor is damaged, then the motor takes in an unusual amount of power while starting. If there are internal problems in the motor, you can always rebuild or replace the motor to solve the air compressor electric motor problem. Finally, hope that this air compressor motor troubleshooting guide was helpful for you to find out the problem of your air compressor motor and fix it.
Knowing how aggravating it is, here are some reasons your air compressor will not start, and a few of the things you need to look at in the hope that understanding them will help you get your air compressor back on track and working effectively. Depending on how much time you want to spend on this compressor George, you can pick up a low-cost 1 HP compressor for under $100 dollars these days, and you could either replace the entire power train of your existing compressor with the new one, or, use the existing compressor only as an extra tank, and fill the tanks on both air compressors from the new one. Turn off the compressor, dump all the air from the tank, close the tank drain, and start the compressor.

Whether they are new or have been in use for years every air compressor will one day have air compressor problems, and fixes to resolve those problems. There are many pages linked below, each addressing many of the issues compressor owners may encounter with their compressor.
Start at the furthest point from the compressor and work your way through the compressor. Keep in mind that early symptoms of a failing compressor could be a sudden influx of water into your air lines because the compressor is working harder or longer and heating up the air more than usual. If you begin to see oil seeping out of air lines or at the outlet of your air hose your compressor pump may be experiencing blow-by and may need a rebuild due to failed piston rings.
how to fix air compressor electric motor Related Question:
Can a compressor motor be repaired?
Air compressor repair can be simple. It’s actually venting the residual pressure from the compressor head so the motor doesn’t have to work as hard on the next startup. The air compressor unloader valve is usually built into the pressure switch assembly.
What causes an air compressor to stop working?
An air compressor problem could stem from one of many issues, such as an air leak, an oil leak or a broken part. In some cases, you might have insufficient pressurization or air flow. In other cases, the compressor might fail to start up or stop running as prompted.
How do you fix an air compressor that won’t start?
If the compressor won’t start with air in tank, replace the check valve. If the compressor won’t start with an empty air tank, replace the pressure switch if it isn’t activating the pump motor. Replace the pump motor if it doesn’t start when activated by the pressure switch.
How do you tell if a compressor is burnt out?
But perhaps the simplest method is the “odor test.” The smell that comes when a hose is connected to the system is both pungent and revealing. Once sniffed, it’s never forgotten and is one of the best indicators of a compressor burn-out.
How do you reset an air compressor?
To reset your reciprocating air compressor, allow time for the compressor to cool down and then push the reset button before attempting to turn the unit on again.
Do air compressors go bad?
Aside from lack of electrical power, air compressors can also fail if it lacks sufficient air pressure in relation to the cut-in pressure. If this happens, check the cut-in pressure settings and adjust them accordingly. It may also be because of the lack of oil.
What causes an electric motor to stop working?
Low resistance is the most common cause of failure in electric motors. It is also often the most difficult to overcome. Under conditions such as overheating, corrosion or physical damage, degradation of the insulation of the internal windings of the motor may occur.
Why my motor is not working?
The most common cause of motor failure, and arguably the most difficult to overcome, is low resistance. Low resistance is caused by the degradation of the insulation of the windings due to conditions such as overheating, corrosion, or physical damage.
Why is my air compressor buzzing?
Without enough air, compressors will stall, and yours may hum when you try to restart it. To check and see if your air filter is the cause of your air compressor humming, unscrew and remove it, then restart your machine. If it works, you need to clean your filter.
What causes electric motors to hum?
A slightly misaligned or bent motor shaft will produce a humming sound. A similar noise can be created if there is a minor fault in the transmission equipment attached to the motor shaft. The latter can be confirmed by disconnecting the motor shaft from the load and turning it on.
What is the possible cause when a motor will not start hums and trips on overload?
When a capacitor deteriorates or opens, the motor has poor starting torque. Poor starting torque may prevent the motor from starting, which will usually trip the overloads.
Is there a fuse for the air compressor?
Blown Fuse or Tripped Breaker Some air compressors have reset switches while others will have in-line fuses that need to be checked. To find them follow the line of power from the air compressor back to the outlet. If you find a blown fuse or tripped breaker go ahead and either replace the fuse or reset the breaker.
Why does an electric motor stop working?
Low resistance is the most common cause of failure in electric motors. It is also often the most difficult to overcome. Under conditions such as overheating, corrosion or physical damage, degradation of the insulation of the internal windings of the motor may occur.
