What to do if the compressor of my Airwell Heat Pump does not start?
If the compressor of your Airwell Heat Pump doesn't start, it may be due to an electronics control problem or protection issue. You should perform diagnostics as described in section 11.3 of the manual and follow the recommended actions.
Why is my Airwell GC 12 DCI not responding to the remote control?
If your Airwell Heat Pump unit isn't responding to the remote control, the remote control message may not be reaching the indoor unit. First, check the remote control batteries. If the batteries are fine, inspect the display and display wiring. If those are OK, replace the display PCB. If the unit still doesn't respond, replace the controller.
What to do if the compressor of my Airwell GC 12 DCI stops during operation?
If the compressor in your Airwell Heat Pump stops during operation but the green LED remains on, it could be due to an electronic control or power supply problem. You should perform diagnostics as described in section 11.3 of the manual and follow the recommended actions.
Why is the indoor fan of my Airwell GC 12 DCI Heat Pump not starting?
If the indoor fan of your Airwell Heat Pump doesn't start, but the louvers are open and the green LED is lit, there could be a few reasons: * If the unit is in heat mode, the coil might not be warm yet. Try changing to cool mode to test. * There might be a problem with the PCB or capacitor. Switch to high speed and check if the power supply to the motor is higher than 130VAC (for triack controlled motor) or higher than 220VAC for fixed speed motors. If it is, replace the capacitor. If not, replace the controller.
What to do if Airwell GC 12 DCI responds to remote but the Green LED doesn't light up?
If your Airwell Heat Pump responds to the remote control message but the Operate indicator (Green LED) doesn't light up, there may be a problem with the display PCB. Replace the display PCB. If the issue persists, replace the controller.
Why is the indoor fan of my Airwell GC 12 DCI Heat Pump working when the unit is off?
If the indoor fan of your Airwell Heat Pump is working when the unit is OFF, and the fan speed can't be changed with the remote, it indicates a PCB problem. Replace the controller.
How to fix a power supply indicator (Red LED) that does not light up on my Airwell GC 12 DCI Heat Pump?
If the power supply indicator (Red LED) on your Airwell Heat Pump doesn't light up, it indicates there's no power supply. Check the power supply. If the power supply is OK, check the display and display wiring. If those are OK, replace the controller.
