Maintenance
Regular maintenance ensures the longevity and optimal performance of your refrigerator.
1. Cleaning
- Always unplug the refrigerator or turn off the gas supply before cleaning.
- Clean the interior and exterior surfaces with a soft cloth and mild detergent. Avoid abrasive cleaners or solvents.

2. Defrosting
This unit features a frost-free system. However, if ice buildup occurs in the freezer compartment, manually defrost the unit:

- Once defrosted, clean and dry the interior before restarting the unit.
3. Long-Term Storage
- If storing the refrigerator for an extended period, ensure it is clean, dry, and the door is slightly ajar to prevent odors and mold growth.
- Disconnect all power sources (LPG, AC, DC).
Troubleshooting
Before contacting customer support, please refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Refrigerator does not cool | No power supply (AC/DC) or no gas supply (LPG). Temperature setting is too high. Poor ventilation around the unit. Door not closed properly. | Check power connections or gas tank. Adjust temperature to a lower setting. Ensure adequate clearance (min. 3 inches) for air circulation. Check door seal and ensure it is fully closed. |
| LPG flame does not ignite | No gas supply or low gas pressure. Ignition sequence not followed correctly. Air in gas line. | Check gas tank and regulator. Ensure sufficient gas. Follow the LPG ignition steps precisely (refer to Operating Instructions). Purge air from the gas line by attempting ignition several times. |
| Excessive ice buildup in freezer | Door left open too long or not sealed properly. High humidity environment. | Ensure door is closed tightly. Check and clean door gasket. This is normal in high humidity; regular defrosting may be required. |
| Unusual odors inside | Food items not properly sealed. Interior needs cleaning. | Store food in airtight containers. Clean the interior thoroughly with a mild solution. |
