My main aim is to make you understand each and every detail of this error.
In this article, we will intensely focus on Changhong Ruba DC Inverter Air Conditioner error codes because of many peoples facing this error so first we start with an indoor model of the Changhong Ruba DC inverter. Make sure you have a full understanding. I requested to you please read this article completely so without any delay. Let’s start our discussion.
F0 Error in Changhong Ruba
So we will discuss the specific error codes of Changhong Ruba DC Inverter Air and their corresponding faults. One of the most common error codes is “F0.” When the F0 error code is showing on your Unit display, it indicates a fault in the indoor fan motor.
If the fan motor is faulty or not working properly and not giving proper feedback, you will need to remove the cover. But before proceeding with this Please ensure that you turn off the indoor unit’s power and unplug the switch. You need to check your motor for potential issues like a motor jammed or a connector loose.
After the cover is open, you can easily locate the fan motor installed just below the PCB. The blower is directly connected to the white-colored fan motor. You see two additional power connectors and a feedback connector present, commonly feedback connector comprises three wires: black, white, and brown.
F2 Error on Changhong Ruba
During our discussion today, our main focus was on the error code “F2.” When your Changhong Ruba DC inverter air conditioner’s display shows this error code and the unit stops working, it indicates a fault in the outdoor temperature sensor. The sensor might be faulty, open, or short-circuited.
To resolve this issue, you can follow these steps: Start by opening the outdoor unit, replacing the sensor, and carefully observe if the error code disappears and the unit starts functioning again. However, if the error continues to persist and the unit does not return to a working condition, it suggests a fault is possible in the outdoor PCB. In this situation, it becomes necessary to check or repair the outdoor PCB to resolve the issue.
Let’s take a look at the outdoor unit and where the outdoor temperature sensor is located:
Before you proceed to opening the cover of the outdoor unit, it’s important to ensure that you turn off the power and unplug it. Once the cover is successfully open, you will find the PCB, which is the heart of the unit’s electronic system and you’ll notice that the outdoor temperature sensor is connected via a yellow connector and a black wire.
Inspecting all connections and wiring to verify their continuity of loose connections or reconnecting any disconnected wires is important. Making sure they are securely in place and properly connected. Once all necessary repairs or adjustments have been made, carefully examine the system to ensure that everything is functioning as expected.
