Air Cooler Not Cooling? Try These Quick and Easy Fixes!

As the summer heat rises, air coolers become a must-have appliance for every home in Pakistan. They are affordable, energy-efficient, and provide quick cooling. But like any machine, air coolers can sometimes run into problems. Whether your cooler is not cooling properly, making noise, or leaking water, don’t worry. You don’t always need to buy a new one—many issues can be solved at home with simple troubleshooting.

In this blog post by Japan Electronics, we’ll explain the most common air cooler problems and how to fix them. So, if your air cooler is giving you a tough time this season, this guide will help you get it back in action.

What to Do When the Air Cooler is Not Starting?

If your air cooler doesn’t start after plugging it in, here are the possible reasons and how to fix them:

1. Check the Power Supply

Make sure the cooler is plugged into a working socket. Try another device in the same socket to confirm if the power is reaching.

2. Inspect the Electrical Fuse

A damaged or blown fuse can stop your cooler from turning on. Open the plug or fuse box and replace the fuse if needed.

3. Circuit Breaker Might Be Tripped

Sometimes, the circuit breaker may trip and cut off power to the appliance. Reset the breaker switch and check again.

4. Damaged Power Cord

Look closely at the power cord. If it has cuts or signs of burning, replace it immediately. A broken cord is a safety hazard.

Air Cooler Is Not Giving Cool Air – What’s Wrong?

Is your air cooler running but not giving cool air? Here’s what might be the issue:

1. Low Water Level

Always check the water tank first. If the tank is empty or low, the cooler will blow warm air. Fill the tank properly before using it.

Tip: Some modern coolers come with auto-fill systems. You can find such models at Japan Electronics with easy water connection options.

2. Dirty or Clogged Cooling Pads

Dust and dirt in the cooling pads can block airflow. Remove the pads, wash them with clean water, and let them dry before placing them back. If they are damaged, replace them.

Honeycomb pads are a great option for replacement. They absorb more water and offer better cooling performance.

3. Clogged Water Tank

If there’s dust or algae in the tank, it can affect the cooling process. Clean the tank with a cloth and mild detergent regularly.

Why is the Water Pump Not Working?

The water pump is the heart of your cooler. It pushes water to the cooling pads. If the pump stops working, cooling performance drops.

1. Check the Water Level Again

Yes, this is important again! If the water is too low, the pump won’t function properly.

2. Blocked Impeller

Inside the pump is a small disc called an impeller. Dirt or debris can jam it. Open the pump cover and clean the impeller carefully using a brush.

3. Replace the Water Pump

If cleaning doesn’t help, the pump motor may be faulty. You can buy a new pump from Japan Electronics or ask a technician for help.

Air Cooler Making Room Humid – What to Do?

Unlike ACs, air coolers need ventilation to work properly. If your room feels sticky or humid:

1. Open Windows and Doors

Always keep one or two windows slightly open. This allows hot air to leave and fresh air to enter, keeping the room comfortable.

2. Use an Exhaust Fan

If your room has poor ventilation, use an exhaust fan. It will pull out warm and humid air from the room.

3. Choose a Cooler with Humidity Control

Modern air coolers now come with humidity control features. If you want to upgrade, check out the new models at Japan Electronics that come with smart features and climate control options.

Air Cooler Smells Bad – Here’s Why

A foul smell coming from your air cooler can ruin your comfort. Here’s what causes it and how to fix it:

1. Stagnant or Dirty Water

If water sits in the tank for too long, bacteria and algae grow. This causes a bad smell. Clean the tank with vinegar or baking soda at least once a week.

2. Dirty Cooling Pads

Wet cooling pads can smell if they’re not cleaned. Remove and wash them every few days, especially if you're using the cooler daily.

3. Dust and Mosquitoes

Some coolers come with mosquito nets and dust filters. These features help keep insects and dirt out of the tank. You can find such options at Japan Electronics, ensuring cleaner and healthier air.

Water Leakage from Air Cooler – Common Causes

If you see water on the floor under your air cooler, it may be due to:

1.       Overfilled Water Tank

Filling the tank too much can lead to overflow. Always fill water just below the maximum level mark.

2.       Ice Chamber Overflow

If your cooler has an ice chamber, don’t fill it to the brim. When the ice melts, it can overflow if not measured properly.

2.       Misaligned Cooling Pads

Improper placement of cooling pads can cause water to spill. Make sure the pads are fitted correctly. Damaged pads should be replaced.

3.       Cracks or Holes in Tank

Check the tank for any holes or cracks. Small holes can be sealed with waterproof sealants. For larger damage, replace the tank or the unit.

FAQs – Common Questions About Air Coolers

Q1: Can I use an air cooler all day?

Yes, you can. But make sure to keep the water tank full and allow some ventilation in the room. Turn it off occasionally to extend motor and pump life.

Q2: Why is my air cooler making a strange noise?

Noise can be caused by a loose fan blade, blocked motor, or dusty pads. Clean the inside, tighten any loose screws, and check if the motor needs servicing.

Q3: How often should I clean my air cooler?

Ideally once a week. Clean the tank, cooling pads, and filters to keep the air fresh and the machine running well.

Q4: Can I use an air cooler in a closed room?
