Blocked Air Filter

A blocked air filter may be the reason why your haier air conditioner won’t turn on. When the air filter is blocked, the flow of air gets restricted, which prevents the air conditioner from turning on. In such a situation, it is recommended to clean or replace the air filter.

Cleaning or replacing your air filter improves the efficiency of the air conditioner and helps it run smoothly. However, if cleaning or replacing the air filter doesn’t solve the problem, it could be worth consulting with a certified technician. They will be able to diagnose the issue and provide the necessary repairs or replacements.

Thermostat Malfunction

If your haier air conditioner won’t turn on, a thermostat malfunction could be the culprit. First, check the thermostat’s temperature setting, ensuring it’s set to cool and at the desired temperature. Secondly, inspect the battery and wires, replacing or tightening as needed.

Power Supply Issues

Haier air conditioners can be a real convenience, but power supply issues can arise at any time. If your air conditioner is not turning on, start by checking whether the power outlet is working properly. You might also want to inspect the unit’s power plug and cable for signs of damage.

Don’t forget to check the fuse or circuit breaker, too. If everything else gets ruled out, it might be necessary to call a technician for a diagnosis. Regular inspection and maintenance with a professional can help ensure you spot any potential issues before they arise, so don’t neglect this important step in extending the life of your air conditioning system.

Dirty Condenser Coils

If your haier air conditioner isn’t turning on, it could be due to dirty condenser coils. These coils, located outside the unit, can accumulate dirt, dust, and debris over time, reducing the efficiency of the air conditioner and causing it to struggle to turn on.

To remedy the issue, first, turn off the power to the unit. Then, use a garden hose or pressure washer to gently clean the coils. Be sure to remove any loose debris with a soft-bristled brush. Once the coils are clean, turn the power back on and test the unit.

If it still won’t turn on, you may need to call a professional for further assistance. Remember to perform regular maintenance on your air conditioner to prevent this issue from occurring in the future.

Faulty Compressor

A faulty compressor is a common reason why your haier air conditioner won’t turn on. It’s responsible for cooling and circulating the refrigerant that cools the air. If it’s not working, your unit won’t function properly. To troubleshoot, start by checking the power supply and ensuring that the thermostat is set correctly.

If those are both in good condition, then it’s possible that the compressor itself is faulty. You may need to call a professional to inspect and repair or replace your compressor. Preventative maintenance, such as cleaning and replacing air filters regularly, can also help prolong the life of your air conditioning unit.


To sum up, when your haier air conditioner won’t turn on, there are various factors that you need to consider. It is essential to identify the root cause of the problem, which could be anything from a blown fuse or tripped circuit breaker to a damaged compressor or faulty motor.

By performing some basic troubleshooting techniques, you might be able to resolve the issue yourself. However, if the issue persists or you are not sure what to do, it is always best to seek assistance from a professional. Always remember to follow the manufacturer’s troubleshooting and maintenance guidelines to prevent any future problems.

With proper care and regular maintenance, your haier air conditioner will provide you with years of reliable service and keep you comfortable all summer long.
