Hello, does it only buzz when it is running?

Correction, it buzzing even when it’s not running

That may be the relay on the control board.

How do I check or what part is recommended to replace

Find the control board, plug it in, and locate the buzzing noise; it will be obvious if that is the part. If the noise is coming from the board, replace the board. If the buzzing noise is coming from somewhere else, keep digging until you locate it.

Can you provide the control board part number
