If you’re wondering “why won’t my DeWalt air compressor turn on,” you’re not alone. This is a common issue that can be caused by a variety of factors. In this blog post, we’ll troubleshoot the most common causes and provide solutions to get your air compressor up and running again.
Electrical Issues
1. Check the Power Source
The first thing to check is the power source. Make sure that the air compressor is plugged into a working outlet. If the outlet is not working, try plugging the air compressor into a different outlet.
2. Check the Circuit Breaker
If the outlet is working, check the circuit breaker. The air compressor may have tripped the circuit breaker, which will prevent it from turning on. Reset the circuit breaker and try turning on the air compressor again.
3. Check the Power Cord
The power cord may be damaged, which can prevent the air compressor from turning on. Inspect the power cord for any cuts or breaks. If the power cord is damaged, it will need to be replaced.
Mechanical Issues
4. Check the Air Filter
A dirty air filter can restrict airflow to the air compressor, which can prevent it from turning on. Remove the air filter and inspect it. If the air filter is dirty, clean it or replace it.
5. Check the Pressure Switch
The pressure switch is responsible for turning on the air compressor when the pressure drops below a certain level. If the pressure switch is faulty, it can prevent the air compressor from turning on. Test the pressure switch by following the manufacturer’s instructions. If the pressure switch is faulty, it will need to be replaced.
6. Check the Motor
The motor is the heart of the air compressor. If the motor is faulty, it can prevent the air compressor from turning on. Inspect the motor for any damage. If the motor is damaged, it will need to be replaced.
7. Check the Unloader Valve
The unloader valve is responsible for releasing pressure from the air compressor when it is turned off. If the unloader valve is faulty, it can prevent the air compressor from turning on. Test the unloader valve by following the manufacturer’s instructions. If the unloader valve is faulty, it will need to be replaced.
Other Issues
8. Check the Oil Level
The oil level should be checked regularly. If the oil level is low, it can prevent the air compressor from turning on. Add oil to the air compressor until the oil level reaches the full mark.
9. Check the Temperature
Air compressors can overheat if they are used for extended periods of time. If the air compressor is overheating, it will automatically shut off. Allow the air compressor to cool down before trying to turn it on again.
