2. Inspect and Lubricate Bearings

High ambient temperatures thin out lubricants, reducing their effectiveness. Use the คู่มือการบำรุงรักษาพัดลมรุ่นยอดนิยมสำหรับฤดูร้อน checklist to verify that all bearing housings are properly greased. For continuous‑duty fans, consider a high‑temperature grease rated above 80°C. Listen for unusual grinding or squealing—these are early signs of bearing wear.

When to Call a Professional

If you notice vibration or noise after lubrication, the bearing may already be damaged. Our local service team can perform vibration analysis and replace bearings before they cause motor failure.

3. Check Motor Ventilation and Temperature

Motors generate their own heat. In summer, that heat adds to room temperature, potentially pushing motor windings beyond their rated limit. Use an infrared thermometer to check motor casing temperature. If it exceeds 85°C, improve motor ventilation or reduce fan load. The คู่มือการบำรุงรักษาพัดลมรุ่นยอดนิยมสำหรับฤดูร้อน recommends installing auxiliary cooling fans for older motors.

4. Verify Belt Tension and Pulley Alignment

Belt‑driven fans are especially vulnerable to summer heat. Belts stretch and crack faster in hot, dry conditions. Check tension monthly—a belt that deflects more than one thumb‑width is too loose. Also inspect pulleys for misalignment; worn belts can slip, reducing airflow and wasting energy.

5. Test Electrical Connections and Overload Protection

Thermal expansion and contraction can loosen terminal screws over time. Before summer peak, tighten all electrical connections and test overload relays. Ensure that the fan’s thermal protection trips at the correct current. This step prevents unexpected shutdowns during heatwaves.
