Possible Causes
Refrigerant leak in evaporator or tubing, Weak compressor, Blocked capillary tube or filter-drier, Faulty pressure or temperature sensing logic
How to Fix / Troubleshooting
Safety: Do not attempt to open the sealed refrigeration system unless you are certified. Unplug the unit before inspection.
- Check evaporator frost pattern: Remove the internal panel and observe the evaporator during operation. A partial frost pattern or only a small section icing indicates a sealed-system issue.
- Listen to compressor: Ensure the compressor runs steadily without excessive clicking or overheating.
- Inspect for oil stains: Look for oily residue on tubing joints, which can indicate a refrigerant leak.
- Basic cleaning: Clean condenser coils and ensure fans are working to rule out airflow issues.
- Professional service: If E17 persists and cooling is poor, contact a qualified refrigeration technician to check pressures, locate leaks, and recharge or repair the system.
