Why Does My Craftsman 125 Psi Air Compressor Not Spin
There are a number of reasons that your Craftsman 125 psi air compressor may not be spinning. The most common reason is that the air compressor is not properly plugged into an outlet. Another possible reason is that the air compressor’s motor may be damaged or defective.
If the motor is not working, the air compressor will not spin.
If your Craftsman 125 PSI air compressor isn’t spinning, there are a few things that could be causing the problem. The most likely cause is that the motor isn’t getting enough power. Check to make sure that the power cord is plugged in and that the outlet has power.
If the outlet is powered but the compressor still won’t start, try plugging it into a different outlet.
Another possibility is that the air compressor’s tank is full and needs to be emptied before it will start again. To do this, turn off the air compressor and open the release valve to let all of the air out.
Once the tank is empty, close the valve and turn on the compressor again.
If neither of these solutions solves your problem, there may be an issue with the motor itself. If you’re not comfortable troubleshooting electrical issues, take your Craftsman 125 PSI air compressor to a qualified repair person for diagnosis and repair.
Craftsman Air Compressor Reset Button
If your Craftsman air compressor isn’t working properly, one possible solution is to reset the button. This can often fix issues with the machine. Here’s how to do it:
First, locate the reset button on your air compressor. It should be near the top of the unit. Once you’ve found it, press and hold the button for about three seconds.
After that, release the button and wait for the machine to start up again. If it doesn’t, try pressing and holding the button for a longer period of time – up to 10 seconds.
If this doesn’t work or if you can’t find the reset button, there could be another issue with your air compressor.
In that case, you’ll need to contact a technician for further assistance.
Troubleshooting Craftsman Air Compressor Problems
Craftsman air compressors are one of the most popular brands on the market. But like any other brand, they can have their share of problems. Here are some tips for troubleshooting Craftsman air compressor problems:
1. Check the power supply. Make sure that the air compressor is plugged into a working outlet and that the circuit breaker is not tripped.
2. Check the pressure gauge.
The pressure gauge should be reading between 0 and 120 psi (pounds per square inch). If it’s reading outside of that range, there could be a problem with the gauge itself or with the air compressor pump.
3. Check for leaks.
Inspect all hoses and fittings for leaks. If you find a leak, tighten the fitting or replace the hose.
4. Drain any water from the tank.
Moisture in the tank can cause rust and other damage to your air compressor. To drain the water, open up the drain valve at the bottom of the tank and let all of the water out until only air is coming out. Then close the valve again.
Craftsman Air Compressor Pressure Switch
A pressure switch is an important part of any air compressor. It is responsible for turning the compressor on and off as needed to maintain proper air pressure. If your pressure switch is not working properly, it can lead to all sorts of problems.
That’s why it’s important to know how to troubleshoot and repair a pressure switch if necessary.
The first thing you need to do if you think there’s an issue with your pressure switch is check the manual that came with your air compressor. This will tell you what the normal operating pressures are supposed to be.
If your compressor isn’t reaching these pressures, then something is definitely wrong.
Once you’ve ruled out simple issues like low air supply or a dirty filter, it’s time to take a closer look at the pressure switch itself. First, check for any visible damage or debris that might be causing problems.
Next, use a multimeter to test the continuity of the switch. If there is no continuity, then the switch needs to be replaced.
If everything looks good with the physical condition of theswitch, then it’s time to move on to testing the electrical connections.
Make sure all wires are connected properly and there are no loose terminals. Again, use a multimeter to test for continuity between all points in the circuit.
Craftsman Evolv Air Compressor Troubleshooting
Most air compressors are pretty reliable. But like any other mechanical device, they can have their issues. And when your air compressor isn’t working properly, it can be a real pain.
Luckily, there are some things you can do to troubleshoot your air compressor and get it up and running again. In this blog post, we’ll go over some of the most common Craftsman Evolv air compressor problems and offer some solutions.
Problem #1: The Air Compressor Won’t Turn On
If your Craftsman Evolv air compressor won’t turn on, the first thing you should check is the power cord. Make sure that it’s plugged in correctly and that the outlet has power. If the cord is fine, then the problem may be with the switch or motor.
You’ll need to take your air compressor to a professional for further diagnosis and repair.
Problem #2: The Air Compressor Is Making Weird Noises
If your Craftsman Evolv air compressor is making strange noises, it could be due to a few different things.
First, check to make sure that nothing is blocking the intake or exhaust ports. If those are clear, then the problem may be with the piston or cylinder walls. These parts can wear out over time and will need to be replaced if they’re damaged.
Again, this is something best left to a professional mechanic.
Air Compressor Runs But Doesn’T Build Pressure
If your air compressor runs but doesn’t build pressure, there are a few possible causes. The most common cause is a problem with the intake valve or gasket. Other potential causes include a clogged air filter, damaged piston rings, or a defective pressure switch.
If you suspect that the intake valve is the problem, check to see if it’s leaking air. If it is, you’ll need to replace the valve or gasket. If the air filter is clogged, clean or replace it.
If the piston rings are damaged, they’ll need to be replaced as well. Finally, if the pressure switch is defective, you’ll need to get a new one from your local hardware store.
Pancake Air Compressor Not Building Pressure
If your pancake air compressor isn’t building pressure, there are a few things you can check to troubleshoot the issue. First, make sure that the air compressor is turned on and that the power switch is in the “on” position. Next, check to see if the air compressor’s intake valve is open.
If it’s not, simply turn the knob to open it. Finally, check the air filter to see if it needs to be replaced. If it’s dirty or clogged, this could be preventing air from flowing into the compressor, which would explain why it’s not building pressure.

What Would Cause an Air Compressor to Not Turn On?
A compressor not turning on can be caused by a few different things. The first thing you should check is if the unit is getting power. If it is plugged in and the outlet has power, then check to see if there is a reset button or switch that may have been tripped.
If none of these solutions work, then it’s possible that the motor inside the compressor has burned out and will need to be replaced.
Why is My Craftsman Air Compressor Not Turning On?
If your Craftsman air compressor isn’t turning on, there are a few possible reasons. It could be an issue with the power supply, the switch, the motor, or the compressor itself. Let’s take a look at each of these possibilities in turn.
First, check to make sure that there is power getting to the air compressor. If it’s plugged into an outlet, make sure that the outlet has power and that the cord is plugged in securely. Next, check the switch to see if it’s turned on.
If not, flip it to the ON position.
If those two things are fine and your air compressor still isn’t turning on, then it’s likely an issue with the motor or compressor itself. If you have access to a multimeter, you can test continuity across the start capacitor and see if there is power flowing through.
If not, then replacing the start capacitor should fix the problem.
If you don’t have a multimeter or aren’t comfortable testing electrical components yourself, then it’s best to take your air compressor to a qualified technician who can diagnose and repair the problem for you.
How Do You Troubleshoot a Craftsman Air Compressor?
