How to Fix / Troubleshooting
Safety first: Unplug the unit immediately if H2 appears repeatedly.
- Clean and clear airflow: Ensure the condenser coil and fan are clean and unobstructed. Clean the filter and surrounding area.
- Check fan operation: When the unit runs, verify that the fan operates at full speed. If the fan is not running or is slow, inspect and replace the fan motor as needed.
- Allow cool-down: Let the unit sit unplugged for at least 30 minutes to cool internal components.
- Professional diagnosis: If H2 persists after cleaning and confirming fan operation, the sealed system may be overheating due to internal issues. Contact a certified technician.
