If you are having issues with your Panasonic product or if you encounter errors while using your home appliances, then you might encounter error code H99 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.
- Clean the indoor filter
- Change any faulty temperature sensor
- Refill the refrigerant
Option 1: Clean the indoor filter.
An issue with the indoor filter can cause this error. This is because the filter prevents foreign objects from entering your home. If you want to clean the indoor filter, you can do so by taking out the outdoor filter first, and then you can clean it.
After cleaning it, put it back in its place and make sure that there are no foreign objects in the device.
Option 2: Change any faulty temperature sensor.
This error is caused by a faulty temperature sensor or an incorrect one. The temperature sensor keeps track of the temperature inside your home appliance. This information is then used to determine whether to run your appliance at full power or to adjust it accordingly.
When there is a problem with this sensor, then this error code will appear on your device’s screen and other problems. To fix this error, you need to replace this faulty sensor with a new one. Make sure that you have checked it for errors before installing a new temperature sensor.
Option 3: Refill the refrigerant.
This error occurs when there is a problem with the refrigerant that powers your appliance. Refrigerant comprises small tubes filled with a liquid that evaporates at a certain temperature. This error occurs when there is not enough refrigerant.
