Blinking Red Light in AC Unit/Heat Pump Not Working

[Pickle Rick]

I have a 2022 Montana 3763BP. The front AC/Heat Pump has a blinking red light I can see from the inside of the camper. I’m unsure what this indicates but I thought I’d ask the group. It seems to be cooling ok, but when on heat it’s only blowing room-temperature air. It works fine last night but I noticed it was not warming when I woke up this morning. I've checked when the temperatures were above 50 degrees so it's not the outside temperature. The blinking red light is on the control box which is how the Lippert InCommand controls the AC. There is a chance the light was always blinking and I never saw it before as it's also blinking on my rear unit which is not a heat pump. So it could be unrelated. I was hoping it was an error code. Any help is appreciated. The control box model is 9430-5501
