  If your Airwell Air Conditioner isn't cooling sufficiently, several factors could be the cause: * The unit size may not be adequate for the room's load. Check if a larger unit is needed. * The piping size might not match the system specifications. Verify correct installation, diameter size and total length according to unit specifications. * There may be a refrigerant leak. Check the refrigeration system. * There may be a refrigerant clog. Inspect and repair any clogging, especially near the EEV. * Electronics control problem or protection. Check for any fault code shown on display board and act accordingly. * Compressor failure. Check if fault code # is shown on display board. If so, fix the problem according to 13.5.7 or replace driver.

  If your Airwell Air Conditioner indoor unit isn't responding to the remote control, first check the remote control batteries. If that doesn't solve the problem, and if the cause is 'Check continuity of each wire of the display wires/pins with Ohm meter', replace the display box or indoor Electronic Assembly.

  If your Airwell Air Conditioner isn't heating sufficiently, it could be due to: * Reverse valve. Check reversing valve operation. * Deicing not performed well (during low outdoors temperatures). Check OCT and OAT thermistors fault codes (#1 and 4). Check OCT thermistor if connected well to pipe. Check OAT thermistor if connected well. Check the thermistors operation.

Why is my Airwell Air Conditioner outdoor unit coil freezing in heat mode?
- T
  Timothy CochranAug 26, 2025
  If the outdoor unit coil of your Airwell Air Conditioner is freezing in heat mode and the base is blocked with ice: * It could be due to hard conditions of low temperatures and high humidity. Check that there are no obstructions to the outdoor unit coil air inlet. * Check that all holes in bottom of outdoor unit base are open and clean from dirt. * Check OCT and OAT thermistors. * Connect base heater.

Why does the fuse keep burning in my Airwell Air Conditioner indoor unit controller?
- Z
  Zachary BaileyAug 30, 2025
  If the fuse in your Airwell Air Conditioner's indoor unit controller has burned out, it could be due to a short circuit between wires. Inspect for any cuts or exposed supply wires, or miss-wiring. Another cause could be failure of the indoor unit fan motor, so check the motor and capacitor for any cuts or exposed wires. If the problem persists, replace the fuse.

How to troubleshoot an Airwell AWAU-YBDE024-H11 Air Conditioner when the indoor fan won't start?
- J
  Jacob BurkeSep 1, 2025
  If the indoor fan of your Airwell Air Conditioner isn't starting, but the louvers are open and the green LED is on, it could be due to several reasons: * If the unit is in heat mode and the coil isn't warm yet, change to Cool or Fan mode. * There may be a failure of the indoor unit fan motor. Check the motor and capacitor for any cuts or exposed wires. * There could be a problem with the controller or motor capacitor. Change to high speed and check the power supply to the motor is higher than 220VAC. * If still not OK, replace indoor Electronic Assembly.

Why is the display board off on my Airwell AWAU-YBDE024-H11 Air Conditioner outdoor unit?
- T
  Tyler HopkinsSep 3, 2025
  If the display board and LEDs on your Airwell Air Conditioner's outdoor unit are off, it could be due to: * No power supply. Check the supply voltage to main terminals L and N with a voltmeter. * Miss-wiring. Check all supply wiring to the controller and terminals according to the wiring diagram. * Loose connection. Check all power wiring connections. * Burnt fuse. Check the fuse on the main board. * If still not OK, replace main board.

Why is the power indicator LED off on my Airwell AWAU-YBDE024-H11 indoor unit?
- S
  shieldsallisonSep 5, 2025
  If the red LED power supply indicator on your Airwell Air Conditioner indoor unit isn't lighting up, it could be due to: * No power supply. Check the supply voltage to main terminals L and N with a voltmeter. * Miss-wiring. Check all supply wiring to the controller and terminals according to the wiring diagram. * Loose connection. Check all power wiring connections. * Display and display cable. Check continuity of each wire of the display wires/pins with an Ohm meter. * If still not OK, check if the fuse is burnt.

What to do if the compressor of my Airwell AWAU-YBDE024-H11 Air Conditioner does not start?
- V
  Victor IngramSep 8, 2025
  If the compressor of your Airwell Air Conditioner isn't starting, it could be due to: * One or some components are not operating well. Check for any fault code shown on the display board and act accordingly. * Electronics control problem or protection. * PFC Chock coil. Check the PFC Chock coil. * Driver failure. Check if fault code # is shown on display board. If so, fix the problem according to 13.5.4 or replace driver. * If still not OK, replace compressor.
