Troubleshooting
If you encounter issues with your heater, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater does not turn on. | Not plugged in; power outlet issue; tip-over switch activated; overheat protection activated. | Ensure plug is fully inserted. Check circuit breaker. Ensure heater is upright on a stable surface. Allow heater to cool down if it overheated. |
| Heater produces a "burning" smell during initial use. | Residual manufacturing oils/coatings burning off. | This is normal for the first few hours of operation. Run the heater on high in a well-ventilated area for approximately two hours. The smell should dissipate. |

Ensure heater is appropriately sized for the room. Close windows/doors. Ensure no obstructions around the heater. Adjust sensor setting in the app for room size. |
| Remote control not working. | Batteries dead or incorrectly inserted; remote out of range. | Replace AAA batteries. Ensure remote is pointed at the heater and within effective range. |
| Wi-Fi app control not connecting. | Incorrect Wi-Fi password; not connected to 2.4G Wi-Fi; router issues. | Verify Wi-Fi password. Ensure your phone and heater are on a 2.4G Wi-Fi network. Restart your router and try pairing again. |
