How to Fix / Troubleshooting
Safety first: Ensure the area around the unit is safe and not icy before approaching.
- Check ambient conditions: Confirm that outdoor temperature is within the specified operating range for your SPRSUN model. Some models lock out below a certain temperature.
- Inspect for ice: Remove snow and ice from around the base and coil. Do not use sharp tools that can damage fins or piping.
- Verify ambient sensor: Compare the displayed outdoor temperature to an accurate thermometer. If readings are far off, the ambient sensor may be faulty.
- Parameter check: For advanced users or technicians, verify that low ambient operation parameters are correctly set according to the installation manual.
- Replace sensor if needed: If E17 appears at normal temperatures, replace the ambient temperature sensor.
