- Remove anything blocking the receiver.
- Test the AC using the manual power button.
If the unit starts manually, the remote is likely the source of the problem.
Allow the Compressor Protection Delay
Many Whirlpool AC models include a built-in delay that prevents the compressor from restarting immediately after the unit has been switched off.
Waiting a few minutes before turning the AC back on can often resolve this issue.
Whirlpool Air Conditioner Remote Control Is Not Working
A non-responsive remote doesn’t always mean the air conditioner itself has developed a fault. In many situations, the issue lies with the remote or its communication with the indoor unit.
Possible Causes
Your Whirlpool air conditioner remote control is not working because of:
- Weak batteries
- Dirty battery terminals
- Damaged buttons
- Faulty infrared transmitter

- Clean the battery contacts.
- Point the remote directly towards the receiver.
- Test the infrared signal using your smartphone camera.
If the remote is transmitting normally but the AC doesn’t respond, the indoor receiver should be inspected.
Whirlpool Air Conditioning Is Not Cooling
When an air conditioner runs without effectively lowering the room temperature, the issue often develops gradually. Reduced cooling performance can usually be traced back to maintenance or airflow problems.
Whether you’re dealing with a Whirlpool air conditioning is not cooling, a Whirlpool AC cooling problem, or wondering, “My Whirlpool air conditioner is not cooling,” the following areas should be checked first.
Dirty Air Filters
As dust collects inside the filters, airflow becomes restricted, making it harder for the AC to cool efficiently.
Common signs include:
- Weak airflow
- Longer cooling time
- Dust around the vents
- Increased electricity consumption
Cleaning the filters regularly helps improve cooling performance and indoor air quality.
Low Refrigerant Level
The refrigerant carries heat from inside your room to the outdoor unit. If the level drops because of a leak, the AC won’t cool effectively.
You may notice:
- Warm air coming from the vents
- Ice on refrigerant pipes
- Continuous compressor operation
- Gradually decreasing cooling performance
Only a trained technician should repair refrigerant leaks and recharge the system.
Incorrect Operating Settings
Sometimes the problem is simply caused by unsuitable settings.
For better cooling:
- Select Cool Mode.
- Set the temperature between 22°C and 24°C.
- Use Auto or High fan speed.
Running the AC in Fan Mode won’t provide cooling.
Blocked Outdoor Unit
The outdoor unit needs unrestricted airflow to release heat properly.
Cooling efficiency can be reduced if:
- Dust covers the condenser.
- Plants or stored objects block ventilation.
- Leaves and debris accumulate around the unit.
Keeping the outdoor unit clean helps maintain consistent cooling.
Whirlpool Air Conditioner Not Working
If your Whirlpool air conditioner is not working, begin by checking whether the issue affects the entire system or only one specific function.
Possible Causes
Your AC may stop operating because of:
- Electrical supply interruption
- Compressor fault
