What fault that lights on led no#3 and no#4 of sharp inverter AY-2599

When start unit cooling fan run and condensing fan run too.

But as compressor begin start up , it go to stop and then led #3 and # 4 on out/door board lights on. Just a second , led no#1 flashes and compressor try to start up again and then failed out at that time.

What fault that lights on of leds number #3 and #4 for all of four leds on main board.

Many Thanks.

Check all it out and find that O/D main board miswork cause by some failed component.

I've fixed and repair it. All modes and funtions now OK.


Now the unit work completely.:)
