Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.

What is the part # for the board you want to replace, please?

A part # would help with the search immensely... I am finding no sign of what you are looking for, so far.

Customer: replied 4 months ago.
Please check attach files pictures
Expert:  Russell H. replied 4 months ago.

Thank you for the pictures.

Just to double-check while I am searching for that... what symptoms is the inverter showing/having?

Customer: replied 4 months ago.
The the outdoor unit does not start. I was told that the pcb board is broken. This happen a month ago when we had a storm with lighting
Expert:  Russell H. replied 4 months ago.

When it does not start, does it show any indicator lights / signs of life, of whatever kind?

Customer: replied 4 months ago.
The indoor unit starts but the outdoor does not. You can see that the board burned.
Expert:  Russell H. replied 4 months ago.

I am having difficulty finding anything about that board, despite the helpful pictures. Is there a number (like a part #) stenciled on the board anywhere, that is not right next to a component or a jumper wire?

I thought I saw a number like 'PbP' inside a square, but a wire obscured it in the picture...

Customer: replied 4 months ago.
If you look at the pictures you will see two numbets one of those is the part number
Expert:  Russell H. replied 4 months ago.

I think you mean the numbers stenciled on the black end-piece ? which of those is the part # please?

Expert:  Russell H. replied 4 months ago.

Those numbers

are completely not found anywhere - except the U. of Oxford Biochemistry department.

I fear my search is so far useless to both of us. I regret this.

Do you have a service manual for the inverter? if you did, the part # for the board would be right there in the manual, and we could get a search done for that part # with some chance of success.
