Troubleshooting
| Step | Confirmation points and methods | Page | YES | NO |
|---|---|---|---|---|
| 1 | Check the suction inlet of the fan for clogging with dirt or foreign objects, and remove. Does the product recover from the error? | CH83 DRV-H Board Cooling Fan | End | Go to step 2 |
| 2 | Check for foreign objects on the CH83 DRV-H Board. If a foreign object is found, remove it. Does the product recover from the error? | CH83 DRV-H Board | End | Go to step 3 |
| 3 | Check if the fan is operating (cable connection check/fan/board/cable broken) Does the product recover from the error? | End | Go to step 4 | |
| 4 | Replace the CH83 DRV-H Board Does the product recover from the error? | CH83 DRV-H Board | End | Go to step 5 |
| 5 | Replace the CH83 DRV-H Board Cooling Fan. Does the product recover from the error? | CH83 DRV-H Board Cooling Fan | End | Escalate to person in charge |
