Hi Angelo,
No, sadly it isnt the gasket. It seems the pre-cut openings on the back are off by about 1/2 to 3/4 of an inch.
I had been dealing with PUI & they said the would send me a new panel after I sent them a bunch of images.
So far, they haven't!
A buddy & I worked for 2 days to trim & kinda fix the panel to fit. It isnt perfect, but it will do until I get things resolved with PUI in getting a new panel.
Its been over a month of emails & I was told a new panel would be sent, but that hasnt materialized as of yet.
