Common Air Cooler Problems and How to Fix Them

I. Introduction: Why Must Air Coolers be Inspected Regularly?

Because air coolers are a very efficient and environmentally responsible type of refrigeration equipment, they are found in homes, shopping malls, manufacturing spaces and warehouses. For B2B purchasers of equipment and distributors, the dependent performance of multiple pieces of equipment will impact customer experience and after sales cost; therefore, periods of adjustments for inspections and repair will provide years of uptime, allowing for continuity of service that is positive for brand reputation and maintenance outlay.

II. Common Problems with Air Coolers and their Solutions

1. Insufficient Cooling Effect

Potential Causes: Not enough water in the tank, water pump clogged, filter is full of dust and debris, cooling pad is too old.

Potential Solutions:

• Check to see if there is enough water to operate and that the water circulation system has no blockages.
• Ensure to regularly clean the cooling pad and filter to restrict airflow energy loss.
• If the cooling pad is too old, be sure to replace it to provide peak cooling capacity performance.

2. Excessive Noise or Vibration when Operating

Potential Causes: Loose fan blades, motor bearings are too old, air cooler is unevenly placed.
Solutions:

1. Retighten fan blades and screws.
2. Check motor for wear or lack of lubrication.
3. Place on a level surface to reduce vibration.

3. Water leakage problem

Possible causes:** Water level too high or aging water tank seals.

Solutions:

• Adjust the float valve or water pump flow rate.
• Inspect and replace aging seals to ensure the water tank is properly sealed.

4. Odor or musty smell

Common causes:** Water not changed for a long time, bacteria or mold growth on the cooling pad.

Solutions:

• Regularly drain accumulated water and clean the water tank with detergent.
• Dry the cooling pad and maintain ventilation; use an antibacterial solution if necessary.

5. Reduced airflow or fan not rotating

Key troubleshooting points:

• Check power connections and capacitors for aging.
• Confirm the motor operating voltage is stable.
• For B2B users, parts and technical support can be quickly obtained through the Wanjiada after-sales team.
