Question about Dewalt Air Tools & Compressors

1 Answer

I start the compressor and it runs and builds up air. After a few moments it will come back on run for a few seconds and turn off. Then it comes back on runs a few seconds and shuts off. It just keeps repeating this cycle

    I'm sorry that I did not explain it very well. I"m not using any air. There is not a hose hooked up to the compressor. The only thing that has been done is plug it in and turning it on. There is no air being released, not even from the pressure relief valve. So it comes on and goes off, over and over again.

    I do appreciate your help

Hi Alisa,

This is normal for an air compressor. As you're using it, it uses up the air inside and must run to build your pressure back up.
When you finish using it, you should always, turn down the pressure knobs and turn it off. Saves on equipment.
You should also drain the tank periodically to let out water that has accumulated inside the tank so the tank won't rust. To do this, loosen the drain under the tank and let the water drain out. Don't forget to tighten it back up or you'll be back asking why you don't have pressure. :>)

I hope this helps. If it does, I'd appreciate your vote.Thanks,

    Hey Alisa,

    This is common for air compressors. I don't manufacture them so I don't know why, somewhere they're losing air a little at a time, so they keep cycling on to keep up the pressure you set. The only cure for this is to set the pressure down to lowest or turn it off.

    Hope that answers your question. Anything else I can help you with on your compressor?

My frigidaire AC starts cooling fine but stops blowing cold air after few minutes and it does not cool at all. I haved turned it off and re-started it and it does the same thing

The compressor is being prematurely turned off. That explains why the cooling stops after a few moments. Either the thermostat is responsible or the electronics working with the therm are responsible for the anomaly.

Freon level is fine because it does cool when compressor is running. U might also want to check the start/run capacitor. That sucker starts the motor and keeps it running after the start. If the run section goes bad the motor will usually stop after it starts.

First, the simple answer - check the AMP draw on the compressor. It should be on the motor or compressor nameplate/tag. Even a small compressor can use alot of power, and blow the breaker if there are other things on a circuit.

Does it seem to run OK for as long as it runs?

EC-12 runs but only builds to 35 psi and continues to run

It looks like there might be a knob which sets the max air pressure coming from the compressor. If there is one, this may have been turned down.

There are usually 3 pressure settings on an electric compressor. Compressor max, pressure switch cut on, and pressure switch cut off.

-If both compressor and fan motor starts and stop, thermostat is the defect.
- If only the compressor check for your outlet no sign of discoloration, check the voltage if normal, check the defective overload protector of the compressor it its external, or compressor itself is defective
