What to do if my Airwell VAR 9 indoor unit is leaking water?
If you notice water leaking from the indoor unit of your Airwell Air Conditioner, the most likely cause is a blocked drainage tube. Inspect the drainage tube and clear any obstructions.
What should I do if the compressor is running, but the outdoor fan on my Airwell VAR 9 isn't working?
If the compressor of your Airwell Air Conditioner is running but the outdoor fan is not working, it could be due to high pressure protection or a problem with the PCB, outdoor fan capacitor, or motor. First, switch the unit to COOL mode, HIGH speed, with a 16°C set point for cooling. Check the outdoor motor power supply voltage; it should be higher than 198 VAC. If the voltage is correct, replace the capacitor. If it still doesn't run, replace the motor. If the voltage is lower than 198 VAC, replace the PCB.
How to fix an Airwell VAR 9 when the green LED is on but the indoor fan won't start?
If the green LED is lit but the indoor fan of your Airwell Air Conditioner does not start, the issue could stem from the PCB, capacitor, or fan motor. Here's what to do: 1. Switch to HIGH speed and check the indoor FAN motor voltage to ensure it's higher than 198VAC. Also, check for any obstructions jamming the fan and remove them. 2. If the voltage is significantly lower than 198VAC, replace the PCB. 3. If the fan is not blocked and the voltage is correct, replace the indoor fan capacitor. 4. If it still doesn't run, replace the indoor fan motor.
Why does the compressor in my Airwell Air Conditioner stop while the green LED stays on?
If the compressor in your Airwell Air Conditioner stops during operation, but the green LED remains on, it could be because the desired temperature has been reached or due to an electronic control or power supply problem. Perform diagnostics to identify the exact cause.
Why won't the compressor start on my Airwell VAR 9?
If the compressor on your Airwell Air Conditioner does not start, it could be due to an electronics control problem or a protection being activated. Perform diagnostics to determine the exact issue.
What to do if my Airwell Air Conditioner's compressor stops due to a protection activation for no apparent reason?
If the compressor of your Airwell Air Conditioner stops because a protection is activated for no apparent reason, it could be due to a control problem or a refrigeration system issue. Perform diagnostics to detect the active protection and take action accordingly.
How to troubleshoot if the red LED power indicator isn't lighting up on my Airwell Air Conditioner?
If the red LED power supply indicator on your Airwell Air Conditioner does not light up, it indicates a lack of power supply. Check the power supply. If the power supply is OK, check the display and display wiring. If those are also OK, replace the PCB.
Why does the indoor fan of my Airwell Air Conditioner run even when the unit is turned off?
If the indoor fan of your Airwell Air Conditioner continues to run even when the unit is turned off, the cause is likely a PCB problem. Replace the controller.
What does it mean when the filter LED comes on in my Airwell Air Conditioner?
When the filter LED illuminates on your Airwell Air Conditioner after 512 hours of operation, it indicates that it is time to clean the air filter. Clean the air filter and then press the RESET button.
