Default Galleria ProAir AC not cooling

We have a 2019 Galleria with the 12 volt air conditioner. It has not worked since our very first trip. Have had it in for repairs 3 times. Coachman has made changes to the operating system, upgrades and mods to the fire fly control panel. So far nothing has worked. It now runs on auto but will shut down and not come back on. Manual also does not cool. We understand that we are not the only ones with this issue. Has anyone satisfactorily solved the problem or have any suggestions that may help? Any help much appreciated. Thank you.

Wow. Sad to hear about problems with your ac unit. Their 12volt powered ac promised high efficiency and I was rooting for it.

Did you have the TSB done? Looks like this could be causing some of your issues.

Please review the Forest River Service Bulletin.

Thanks, I honestly don’t know what that is and the link isn’t working on my iPad. Dealer said they have done all recalls and updates on the vehicle including ac and the replacement of the “fire fly “ panel. It may be something I’m not doing correctly.

That link is bad, but I pasted it into my browser. Now works fine on my iPad. Try this one. . .

https://dealers.forestriverinc.com/d.../225V21025.pdf

It is a 27 page Service Bulletin regarding a fix effecting ProAir A/C performance.

Here is what it says about the issue:

"The thermistor installed in the vehicle is not in an optimal location. The thermistor will need relocated, and software upgrade to the FireFly electronic control system is also required."

You can look at it and ask dealer if they have applied the specific bulletin.

This is not a recall, but a TSB - fix for the PROAIR AC on the Galleria. There are a lot of steps here for this fix, including replacement of the AC control board up on the roof. I would say this is a very difficult and complex fix. If one or more steps was done wrong it could cause issues. The highest likelihood of issues with the PROAIR is this or because of this. Since your system is still not working correctly if it is you or it is broken needs to be reviewed by the specialists that know the system best. This may or may not be your dealer.

This may also give others on the forum here ideas as to what work may of been completed on your rig. I hope you are able to get this worked out.

Do you have the Li3 batteries? Does it work at all, on shore power?

Honestly don’t know. They made so many changes I lost track of what was done.
