If you are experiencing problems with your Panasonic products or if you are experiencing errors while using your home appliances, you might be able to get error code H33 on your device.
If you get this message, you will need to check the following options.
If the system displays error codes, it indicates that the AC motor is defective, the signal transmission inside the house is defective, or there is a high-pressure problem when the air conditioner is running.
H33 means the power supply to your device is detected at the level that it requires, based on the data that is transmitted from the indoor/outdoor units. What might cause malfunctions in your air conditioner is that you connected the wrong models of AC and used the wrong PCBs for the indoor and outdoor units and thus your AC won't work. You can try replacing the computer board that controls the AC unit.
Check if the fan in the outdoor unit is working as it should and make the necessary repairs or replaceable parts. Check if the refrigerant levels in your AC system are normal. If not, you should try to fill the unit with new refrigerant. If the refrigerant levels are still normal, you should change the refrigerant in the system and recharge the compressor with the correct amount of refrigerant. Check if the valves inside the unit are jammed or if the strainer is frozen and replace it.
Check if the thermostat in your air conditioner is working as designed and if the sensor in your outdoor unit works as required (see the diagram in your AC service manual). If the pipe temperature sensor is correctly set according to the diagram, start replacing the compressor. If not, try to set the right setting in the electronics on the control board. If it does not, you should replace the power control board.
If a power surge or short circuit threatens to cause the power line to be cut, the main switch on your power supply will be turned off. If it is only your power line that is threatened, the switch on the AC line will also be off.
You can also try calling Panasonic customer support or visiting their website. You will need to inform the customer service department of the error message you received. That person will help you figure out what you should do to fix the error message and will also provide you with a solution.
