Since I feel very comfortable knowing that most of us do not know all things, I am used to just going for the info I can find online as it tends to be more reliable.

There may be somebody come along who knows that AC well enough to spot exactly what the red light means but in the meantime, I would go for looking on the unit for a tag that gives me the brand and model to use to search for the repair/owners manual for that exact unit.

Then when I get into wanting to look at an item but not knowingwhere or what that item may look like, the parts catalog has some good info for ID of those parts on page 198 of this manual:

Sorry, the best I can do is referr you to somebody who might know more!!!

I'm currently fighting issues on my 2002 Winnebago 32v and came across this post. Is this the light you are getting as well?

My basement air operated with one compressor. It would cool but couldn’t keep up during the day. I replaced mine. Locate the model/serial plate and you can order an exact replacement unit. The cost was about $4500 including shipping. Finding qualified experienced techs that will pull and replace or repair is your real problem. Good luck, it took me three weeks for the techs to arrive. It only took 2 hours to replace the unit.
Oh the serial/model plate in mine is on the unit cabinet by the air vent attachment. When I raised the cover I saw it and took a photo.
