Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
N/A | The compressor doesn't run (battery-connected) | Interruption in connection between battery and electronics, faulty main switch, blown supply line fuse, battery voltage too low, loose cables, poor contact (corrosion) | Establish a connection, replace main switch, replace supply line fuse, charge battery, replace cable with correct cross-section based on length | DIY Safe |
N/A | The compressor isn't running (connected to AC supply) | Interruption in supply cable, faulty main switch, blown supply line fuse | Establish a connection, replace main switch, replace supply line fuse | DIY Safe |
N/A | Poor cooling, interior temperature increases | Could be too-high ambient temperature, poor ventilation, a dirty condenser, a faulty fan, or a drained battery | Move refrigerator to another location, clean the condenser, replace the fan, charge the battery | DIY Check / Tech Fallback |
N/A | Unusual noises (loud humming) | Part of the refrigerant circuit is touching the wall so can't move freely, or something is wedged behind the cooling unit | Carefully bend the component clear of whatever it's touching, and remove any foreign object. | DIY Safe |
