All,
We haven't used our heater for a few years so I decided to go out and make sure everything looked good.
Unfortunately, I couldn't get it to work.

The backlight of the display works but nothing ever shows up on the screen - and it doesn't appear anything else is happening.
The power button turns the display light on/off. The up/down arrows don't do anything. Holding them at the same time doesn't do anything.
I took off the control board that holds the display and made sure everything was cleaned, fuse was good, etc.

The fact that I don't hear the heater try to kick on makes me think the issue isn't the actual display but rather the board itself or something else.

Any other ideas before I spend $300 on a new board?

Thanks in advance!

Model: P-D336A-EN-C
It appears it was manufactured in 2013.
