Error codes for air conditioners Polaris (Polaris, Polaris) - decryption and instructions

Each Polaris air conditioner has the option of self-diagnosing problems. If faults are detected, the electronics turn off the air conditioner and display the air conditioner error code Polaris.

To display error codes for Polaris air conditioners, diodes are used located on the front side of the indoor unit. If the self-test detects a malfunction, the diodes blink or glow at a predetermined frequency corresponding to a specific error. If several faults are detected at the same time, the most serious code is displayed first.

Do-it-yourself troubleshooting

In some cases, stopping the air conditioner is a temporary solution to the system to prevent more serious damage.

To deal with such malfunctions, no special knowledge is needed.

What is a malfunction	What to do?
Air conditioning does not start	Make sure that current flows through the wires. Make sure the “Drain condensate” light is on. Check the room temperature.
Air conditioner cools / warms slightly	Protect the air conditioner from bright sunlight. Close all doors and windows. Make sure that the room is not heated with radiators or fan heaters.
The air conditioner works, but does not warm / cool at all	Make sure the filters are clean. Check that the air duct is clean. Check the room temperature.
Air conditioning makes too much noise	Is the air conditioner skewed? The base should be flat and horizontal. There should be no shaking of equipment during operation.
Compressor stands	The compressor overheat relay has probably tripped. Leave the air conditioner turned off for a while, then try turning it on again. Prior to repair, the device can be used as a fan.

If the above recommendations did not lead to a correction of the air conditioner, the device should be de-energized and a master should be called from the service center.
