Proactive Maintenance Guide
To extend the lifespan of your refrigerator and keep it running efficiently in Nigeria's humid climate, follow these essential maintenance protocols:
Cleaning Routine
- Coils: Vacuum the condenser coils every 6 months to prevent compressor overheating.
- Gaskets: Wipe door seals with warm soapy water to ensure an airtight lock.
- Drain: Flush the defrost drain hole to prevent internal water pooling.
Usage Habits
- Loading: Avoid overloading; air must circulate freely between food items.
- Placement: Ensure at least 2 inches of space between the fridge and the wall for ventilation.
- Stabilizer: Always use a high-quality voltage stabilizer to protect against power surges.
Average Lifespan: 10–15 Years
With regular maintenance and a stable power supply, top-tier brands like LG, Samsung, and Bosch can easily exceed 15 years of service.
