A 12v air compressor is a portable device used to inflate or deflate things like tires, rafts, and beach balls. Often powered by car batteries, they are perfect for roadside emergencies and camping trips. It is essential to maintain these mini air compressors regularly to keep their performance at its peak.
If your 12v air compressor stops working properly, there is a simple fix that you can do to get it running again.
But the question arrives here Why air compressor stop working: The most common issue with 12v air compressors is the build-up of dirt and dust inside the air intake. This can cause the compressor to overheat or stop working altogether.
Here we show you how to repair a 12v air compressor. This is a fairly easy process, but you must take your time and follow the instructions carefully. We will also provide some tips on common problems and how to prevent them from happening again. So, if your air compressor is not working properly, read on:
How to fix 12v air compressor
First make sure your air compressor is turned off. Once you have ensured that the compressor is turned off and unplugged, it is time to take it apart. This is a fairly simple process, but you must be very careful not to damage any internal components. The procedure is as follows:
Step 1: Take it apart and see what’s inside.
The 12-volt air compressor is quite simple to take apart, and it doesn’t require any special tools. You need a screwdriver to remove the screws that hold the casing together. Once the screws are removed, you can lift off the top and bottom covers and expose the inner workings of the compressor.
The inside of a 12v air compressor is pretty simple to understand. When the motor turns, it spins this gear connected to the crankshaft.
Two bushings support the crankshaft and it has a shaft that’s connected to the connecting rod. The piston rings are connected to the connecting rod for greater efficiency during compression as they move up and down through polished metal cylinders.
A reed valve allows air to enter through a tiny hole on top of your cylinder head when the piston moves down. When the pressure rises, the valve is shut off by the pressure in the cylinder.
Step 2: Clean and lubricate the crankcase.
After you’ve removed the crankshaft, it’s time to clean and oil the crankcase. For this, you should use a flavor injector that uses synthetic grease of high quality. it will let you put grease in places where it wouldn’t be possible.
Remove the piston from the cylinder and clean it separately. Now, it is time to clean the inside of the motor and lubricate it as well. You will need to remove the end caps from the motor to do this. Be sure to remove all the dirt and grime that has built up over time.
Lubrication is essential since the crankshaft bushings require a lot of lubrication. If you grease all of the angle grinders, it will extend their life for a long time. This will remove the residue that builds up inside, which can affect your compressor’s performance. Over time, this build-up gets thicker and can cause small parts in your motor to stick.
Step 3: Check the Hose
The third step is to check the hose. If the hose on your pump is damaged, you can go to any auto store and purchase a high-quality automotive hose that can withstand up to 100 PSI. Alternately, you can cut the hose off and secure it with a hose clamp.
Step 4: Power Supply Repair
If your compressor isn’t getting power, the issue is most likely with your power supply. To test this, remove the power cord from the compressor and plug it into a known working outlet. If the compressor still doesn’t work, the problem is most likely with the cigarette lighter plug.
To repair this, use a flathead screwdriver to loosen the cover. There is a fuse inside the lighter socket. If it’s broken, you’ll need to replace it with a new one. If the 12v air compressor fuse is working fine, the problem is with the pin. Make it larger by using your screwdriver to open the hole a little bigger so that the pin can easily slide in. Now put it back together and test it.
Step 5: Check the cooling fan
If your 12v air compressor is overheating, you need to check the cooling fan. If it is not working, you can clean it or replace it.
So now you know the process of repairing a 12v air compressor. Thus, it is beneficial for those with a 12v air compressor and wants to repair it. Regular maintenance is essential for keeping your 12v air compressor running smoothly. By following these simple steps, you can keep your compressor in good condition and get it back up and running for your next car emergency.
