i got attend a similar case and same error outdoor (Red)LED1 blinking twice.
i found is the outdoor one of the LEV coil is faulty.
after replace the LEV coil,the system back to normal.
important:
please is you face the same problem or smilar case,you need to check LEV coil,LEV body or compressor or pcb.

Thinks very good sir your video information very good sir
Thanks
Thank you.
The compressor has pumped the refrigerant up to 16bar (240PSI). What should be the pressure here? Are the windings faulty to the compressor. The current drawn was 7A, when the compressor has cut off. Should not the PCB get replaced, as well, if the compressor has failed?
Thanks
Thanks 🙏🙏
How r u keeping? Thanks for video.
Good.Thanks.
HI, The CONDENSER MXY-4A38VA-p3 takes a long time to cool the room even i set at 19 deg c. I am running room no.1 FCU MXY-FD13VA-R1 only , it running amp is about 2.5 to 3 Amps. sometimes it can load up to 6.5Amp for a short period and drop back to 2.5 to 3 amp. another problem is when room no. 2 is running and when I ON room no.1, room no. 2 temperature goes up and the running amps for both units is about 2.5 to 3.5 amp. then stable at about 3.amp. in total there are 4 FCU. Please advise, Thanks you.
Are you try another two fcu.
What is the pressure when you on two fcu.
@@BonMj if i try running all the 4 fcu i can get about 16 to 16.5amp . i did not climb out of the windows to physical check the pressure as i dont have the pressure gauge. is there any way i can contact you. Thanks
@@lkwong8784 gas pressure important too.
Hi , Base on the above problem to the condenser could it be the control PCB is having problem ? any way for me to email to you in private? Thanks.
@@lkwong8784 is power pcb.

Check EEV
@@BonMj thanks sir
Singapore???
Yes
Hi
May I know MXY-3G28VA can be setting to the Maximum power speed?
Hi.
Power mode
@@BonMj how to adjust?
Follow my video.
Power Mode.
@@BonMj do u have that video links?
@@ngbop4541 tonight i update
Hi 你好
你好
换外机还是，换外机电板？
Compressor+power board
@@BonMj 老师，刚才你把出fan motor wire 是想 test fan motor 有没有坏么？
@@janshaw5472 我是拿compressor wire出来，一班如果风扇会运转，compressor坏 的可能性就比较大，最好量下从pcb有没有电去compressor.如果没有voltage,那就可能电板坏，如果有voltage, 可能compressor 坏。
这个model最好也check LEV coil, LEV coil坏也会这样。
@@BonMj ok 谢谢
This is ipm pcb faulty
Mitsiis not reliable like old japanese thongs
