Why is the red LED off on my Airwell SX 30 DCI indoor unit?
If the indoor unit power supply indicator (Red LED) does not light up on your Airwell Heat Pump, it indicates there is no power supply. Check the power supply. If it's OK, check the display and display wiring. If that's OK, replace the controller.
Why is my Airwell SX 30 DCI Heat Pump 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 SX 30 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 SX 30 DCI 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 Heat Pump 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 doesn't the green LED light up on my Airwell SX 30 DCI Heat Pump?
If the indoor unit responds to the remote control message, but the Operate indicator (Green LED) does not light up on your Airwell Heat Pump, it indicates a problem with the display PCB. Replace the display PCB. If the issue persists, replace the controller.
What to do if my Airwell Heat Pump doesn't respond to the remote?
If the indoor unit of your Airwell Heat Pump does not respond to the remote control, it could be that the remote control message isn't reaching the unit. You should check the remote control batteries. If they are OK, check the display and display wiring. If that's OK, replace the display PCB. If it's still not working, replace the controller.
Why is my Airwell SX 30 DCI causing interference with other appliances?
If other home appliances are operating faulty, such as noise in the television picture, or distortion or static in the radio sound, it could be due to EMC interference by the Airwell A/C unit. You should check for EMC problems.
What causes my Airwell SX 30 DCI to stop suddenly?
If the Airwell Heat Pump suddenly stops during operation, it could be due to EMC interference. You should check for EMC problems.
What to do if there's water leakage from my Airwell SX 30 DCI Heat Pump indoor unit?
