the filter screen can be cleaned and reset by pressing the key on the remote controller (continuously pressing the high-efficiency key for 5 seconds, and the remote controller sends a cleaning reset code). (This scheme is a general scheme). The filter screen can be cleaned and reset through the operation of "emergency button" on the indoor controller.
in the cleaning prompt state, press the "emergency button" once to reset and cancel the cleaning prompt, and the emergency button will restore its original function. (If the controller is designed with a dedicated clean reset key, the clean reset key is preferred).
after exiting the cleaning prompt state, the air conditioner returns to the normal display and operation state, and the accumulated timing of the fan is cleared. FC is displayed, which is a patented technology-the filter screen is full of dust, prompting that the filter screen is required to be cleaned, and the words FC are written after cleaning.
second, Haier air conditioner reported fc failure reason:
When the air conditioner runs for 5 hours, FCA function runs to remind users to clean the filter screen and ensure that the filter screen is clean, not a failure.
Solution:
When the FCA function of the air conditioner is reminded, press and hold the FCA reset button for 3 seconds continuously, the "FC" character on the digital display screen of the indoor unit disappears and the user-set temperature is displayed normally, and the FCA function is released. Then cut off the power and take out the filter for cleaning.
Generally, the air filter in the indoor unit of air conditioner is valid for 6 months under normal use environment.
We should clean the air conditioning filters with initial and intermediate effects at least once a month. If there is a lot of dust, the cleaning cycle needs to be shortened, and the air conditioning filters with high efficiency should be replaced in time according to the cleaning requirements.
When cleaning the air conditioner filter, warm water below 4 degrees should be used, and it is not allowed to be rubbed. When the air filter is dirty, we can use neutral detergent for decontamination. If the air filter is not very dirty, we can directly use water spray for cleaning.
after the air conditioning filter is cleaned, fully dry the water on it before putting it into the central air conditioning unit. When installing the air filter, pay attention to the positive and negative air flow surfaces on the filter and install it in strict accordance with the correct requirements.
3. Haier air conditioner displays fc Meaning:
1. When "FC" flashes on the display screen of the indoor unit of the air conditioner, it indicates that the unit is performing the "filter cleaning prompt function", prompting that the filter needs to be cleaned. Some products will beep while displaying "FC". The above phenomenon should be explained to the user. This is not a machine problem, and FC is not a machine fault code.
2. FC is a reminder that the air conditioner should clean the filter, which is a humanized reminder function. This is a protection code of the air conditioner. When the internal fan of the air conditioner runs for 2 hours, it will enter the state of filter cleaning prompt, and the FC prompt will appear.
3. It is very important to keep the filter clean frequently. Without the prompt function, users will continue to use it in a harmful state.
