If you are having issues with your Haier product or if you encounter errors while using your home appliances, then you might encounter error code F4 on your device’s screen. This error can occur when there is an issue with your device or it can occur when there is an issue with your power supply.
Sometimes, common device errors or server problems can also cause this error.
To fix this error, you need to try a few solutions.
- Replace the compressor
- Replace the temperature sensor
- Check for faulty indoor fan motor
- Replace the fan motor
One possible solution is to replace the compressor of your AC unit. A compressor is a small unit that is located on the back of your AC unit. The compressor will cool the air coming from your air conditioner and send it to the outside.
If your compressor is damaged, then this can be a reason for error code F4.
There are two different types of compressors in use today. One type of compressor uses oil and is known as an oil-free compressor. The other type of compressor uses oil and is known as an oil-filled or traditional compressor.
To fix this error, you need to make sure that you are using an oil-free type of compressor.
Another possible solution is to replace the temperature sensor in your AC unit. This sensor will help regulate the temperature inside your AC unit and help it keep a constant temperature level inside your home. If this sensor is damaged, then this can be a reason for error code F4 on your device’s screen.
The next possible solution is to replace the fan motor of your AC unit. The fan motor will help cool the air coming from your air conditioner and send it outside of your home through ducts. If your fan motor is damaged, then this can be a reason for error code F4 on your device’s screen.
The last possible solution is to contact your AC's manufacturer. If you purchased your AC unit from a dealer, then contact the dealer. If you purchased your AC unit from a local store, then contact the store. If you have a model number for your AC unit, then use that to contact the manufacturer.
