Why my Daikin LXE10E-A4 unit does not operate?
If your Daikin Air Conditioner isn't operating, start by checking for a power failure. Make sure the equipment power supply is turned ON and that the power plug is properly connected and making good contact. Also, verify that the circuit breaker is not OFF by resetting it. If an alarm caused the shutdown, investigate and reset the alarm.
What to do if Daikin LXE10E-A4 does not turn on?
If your Daikin Air Conditioner isn't operating, and you've ruled out power issues, inspect the wiring inside the unit for any short circuits and repair as needed. Also, check the power transformer for wire breakage or an open phase and correct any issues found. Ensure the UNIT ON/OFF key is set to ON.
How to fix Daikin LXE10E-A4 that is not working?
If your Daikin Air Conditioner isn't operating, a burned-out fuse could be the culprit. Replace the burned-out fuse. Additionally, a burned out or short-circuited solenoid valve coil or contactor coil can prevent operation; in this case, replace the solenoid valve coil or replace the contactor coil.
What to do if my Daikin Air Conditioner won't start?
If your Daikin Air Conditioner isn't operating, it might be due to an open phase (R or T). Check and correct the open phase. Also, wire breakage in the control circuit transformer can cause this issue; check for and repair any wire breakage.
