I just replaced my gimbal due to error codes 4021 which I could not resolve.  Now that it is back together, my new error codes are 40012 and 40021.  I am still getting 40002 and 40003.   What can I try at home to resolve this before I send it in for repair?

For us to be able to assist you further may we know what is the model of the DJI Mavic you have? In addition, by means replaced the gimbal, you had self repaired the drone?

Thank you for the quick reply. The Drone is a DJI Mavic Mini that I have owned for about 3 months. It does not have DJI care Refresh on it. The trouble started last week with error codes (4002 and 4003) for the gimbal being stuck or overloaded. I went through all of the YouTube video possibilities for getting it to operate correctly again, with no luck. I ordered a new gimbal with camera replacement from an authorized DJI dealer, installed the new gimbal and reassembled. The new gimbal works just like the other gimbal, when you start the grown kid goes through a default motion up and down and back and forth, then it stops. Camera works just fine turns on and off and I get my picture just fine through my iPad. There is just no gimbal control, and I cannot get it to level or move and the button on the remote does not operate.  See the picture I posted in my original post.  I need any direction any one can offer.
Thanks

Hi Alexdky33, sorry to hear about the issue. Please try to do gimbal and IMU calibration. If the issue persists, may I know if you have done the gimbal repair before? If so, you may send the drone back for further diagnosis and service.
Please contact the reseller or our support via email at http://www.dji.com/support to start a case.
