Hi and welcome to the thread!
Working the bugs out is a bit of a trial but I love my Gemini;-)
My fridge would only work on the lp mode until the dealership replaced the "eyebrow" which was the control panel above it. Of course on the phone they suggested I press harder (didn't work and I sure didn't want to cause any damage that could be considered user error) You might check to see if you can clear the air from the line (on /off a few time in the lp mode) so at least one mode works.
