What to do if Airwell Inverter suddenly stops during operation?
If your Airwell Inverter stops suddenly during operation, it might be due to EMC interference to the A/C unit. Check for EMC problems.
What causes other home appliances to malfunction when Airwell Inverter is working?
If other home appliances are malfunctioning (e.g., noise in the TV picture, static in the radio) when your Airwell Inverter is operating, it could be due to EMC interference from the A/C unit. Check for EMC problems.
What to do if Airwell DLF 18 DCI fuse burned in indoor unit controller?
If the fuse in your Airwell Inverter indoor unit controller has burned out, it could be due to: * A short circuit between wires, so check for any cuts or exposed supply wires or miss-wiring. * Failure of the indoor unit fan motor, so check the motor and capacitor and look for any cuts or exposed wires.
Why Airwell DLF 18 DCI Inverter not all units are operating?
If not all units of your Airwell Inverter system are operating, it could be due to communication problems between the outdoor and indoor units. Check the communication between them.
What causes freezing of outdoor unit coil in heat mode of Airwell DLF 18 DCI Inverter?
Freezing of the outdoor unit coil in heat mode, along with ice buildup, in your Airwell Inverter can be caused by: * Hard conditions of low temperatures and high humidity. In this case, check that there are no obstructions to the outdoor unit coil air inlet.
