No Power

Make sure that the power cord is plugged in securely. The power cord should be plugged into both the outlet and the GDM330.

Check the fuse. The GDM330 has a fuse that can blow if there is a power surge or other problem. The fuse is located on the back of the unit.

Check the circuit breaker. The circuit breaker for the outlet that the GDM330 is plugged into may have tripped. Check the circuit breaker and reset it if necessary.

Try a different outlet. If the GDM330 is not working in one outlet, try plugging it into a different outlet.

Contact Ryobi customer support. If you have checked all of the above and the GDM330 is still not working, you can contact Ryobi customer support for help.

Here are some additional troubleshooting tips:

If the power cord is plugged in securely and the fuse is not blown, try resetting the GDM330 by unplugging it from the outlet for 30 seconds and then plugging it back in.

If you are still having problems, try cleaning the contacts on the power cord and the GDM330.

If you have tried all of the above and the GDM330 is still not working, it may be defective. You can contact Ryobi customer support for a replacement unit.

I hope this helps! Let me know if you have any other questions.
