Please try below suggestion:
1) unplug the incubator power connector which located on the back of the incubator top cover for 2 minutes
2) replug that power connector, ensure the connector is pushed fully home in its socket
3) reset the incubator by pressing “MENU” and “-“ buttons at the same time for around 5 seconds until you hear sound feedback, and screen blink once, it means incubator has been successfully reseted, the hatch day count down now will back to 21 day, you can press the MENU button to check, if now the days show 21, means you have reset successfully.
4) then adjust hatch days to the actual correct hatch day remaining
5) wait for couple hours to check if the eggs are moving
Please let us know if this works.
