There are three main functions that are needed for a compressor to work. They need power, be able to maintain pressure and control the flow of the compressed air. Air compressors can explode if you are not practising the correct air compressor maintenance and repairs.
Below are a few DIY fixes that you can try at home before calling a professional in:
DIY air compressor repair
There are three main DIY fixes. Most of the problems that occur with an air compressor will fall into these categories. Remember that the high-pressure air compressors can rupture if the tank becomes damaged. If you have complex repairs that need to be done, consider leaving it to the professionals.
Adjusting the airflow
Take the plastic cover off the top of your air compressor and remove the screws. Now you need to lift the cover off, which will allow you to access the two screws that are underneath near the pressure maintaining valve. The top screw will turn the air compressor off, and the bottom one will turn it on.
You need to turn the air compressor on and then off then go ahead on checking the air compressor settings. You will need to adjust the pressure using the upper screw.
Now tighten the screw to raise the pressure, or to loosen the screw which will reduce your pressure. Connect the pressure release valve and keep an eye on the pressure when the air compressor kicks back in again. You can use the lower screw to adjust the setting. Once you have found the correct pressure, then you need to replace the cover and the screws.
Restoring the Power
Begin with the obvious fix. Ensure the machine is plugged in and the switch is on. If the compressor is still not turning on, try the reset button. The button can often be found on the side of the motor right near the power cord. The button will either be red or black. Hitting this button will reset the circuit breaker. If this doesn’t restore your power, then check over the power cord to ensure it is in good order. Now try and plug the compressor into a completely new socket. Ensure the circuit breaker is not tripped. You can flip the switch off and back on again. After these few DIY fixes if the air compressor is still not turning on, then take it to the technician.
Repairing any leaks
Start off by unplugging hoses and tools. Startup the compressor, so it starts to charge. Now mix up a solution of detergent and water and spray it around the fitting on the compressor. If you see a formation of bubbles, then it suggests that you have a leak. You need to release the pressure from the tank which is done via switching off the compressor altogether.
Now remove the fittings where you have seen the bubbles forming. You can use some plumbers tape here on the thread of the joints. Now put the fittings on and ensure they are tight. Turn on the air compressor and allow it to charge up again.
Now you want to test again with the soapy water and look for bubbles forming. If you still see bubbles, then you just need to discharge the air compressor and use the plumber’s tape.
Finding the parts you need
These are the quick fixes for the common problems that occur with air compressors.
There are other fixes that require more knowledge such as changing tubing, valves, gauges and solenoids. Tutorials can be found online and Youtube if you are unsure of what to do. Otherwise, seek advice from a professional technician.
