The 3 methods to activate Mitsubishi air conditioner without a remote control include: using the power button, a bridge, and a smartphone. Details of each method will be explored in the following sections.
Method 1: Utilizing the Power Button on the Indoor Unit
Most air conditioner manufacturers, including Mitsubishi, incorporate a power button on the indoor unit to help users turn on the machine in case the remote is lost.
The location of the power button on the indoor unit varies depending on the AC brand. For Mitsubishi air conditioners, the power button is usually located on the right-hand side, facing outward from the indoor unit.
To activate the power button for your Mitsubishi air conditioner, first flip the machine's faceplate up. Then, use a pointed object like a pen to press the power button.
Note: When using the power button method to turn on your Mitsubishi air conditioner, you won't be able to adjust any functions of the unit. The AC will operate in AUTO mode, maintaining a standard temperature of 24 degrees Celsius.

Method 2: Utilizing a Separate Switch for Mitsubishi Air Conditioner
Typically, when installing an air conditioner, a separate switch is also installed for the unit. This switch not only protects the air conditioner from short-circuiting but also allows you to turn on the Mitsubishi air conditioner without needing a remote control.
You can activate the Mitsubishi air conditioner using the separate switch because the unit is equipped with a feature to restart automatically after a power outage. If there's a sudden power failure, the Mitsubishi air conditioner will automatically remember settings such as mode, temperature, airflow direction, etc. When you turn on the separate switch for the unit, the Mitsubishi air conditioner will automatically restore the parameters from the last use.

Method 3: Turning on Mitsubishi Air Conditioner via Smartphone
Another alternative you can use to activate your Mitsubishi air conditioner when you don't have a remote control or it's malfunctioning is to use your smartphone directly.
In this method, you should search for Mitsubishi air conditioner control apps such as Tado° Cooling, IR Remote, ASmart Remote IR, and download them onto your phone. Then, you can use it just like a regular remote control.

Mitsubishi air conditioners come from Japan, under the management of the large industrial conglomerate Mitsubishi Group, established in 1870. Mitsubishi Electric and Mitsubishi Heavy are two renowned air conditioning brands both produced by the Mitsubishi Group. However, Mitsubishi Electric and Mitsubishi Heavy are two separate companies with entirely different technologies.
For example, Mitsubishi Electric air conditioners feature modern design and competitive pricing, while Mitsubishi Heavy air conditioners have traditional design and high durability. Both Mitsubishi Electric and Mitsubishi Heavy air conditioning products are highly trusted in Vietnam.
