Fleetwood Revolution LE 2005

[BARBCROMWELL]

New here and a new RV owner. I am trying to set my air conditioner, RVP 9000 series (upon recommendation) to 105 degrees for the summer when temperatures are over 100 degrees outside which makes it really hot inside the RV. We have 2 zones and I can only get it to 90. Any suggestions?

So most AC units will only get their output temps about twenty degrees cooler than the ambient temperature

Thank you so much. I am actually trying to set the air at 105 so that when it gets hotter inside it would cool it to that degrees. I'm not trying to cool it any less until were using it and that doesnt seem to be a problem.

You're trying to set the AC temp to 105?

In my limited knowledge, most thermostats cannot be set that high.
Only ideas I have:
1) If your thermostat has an “offset” function to allow to to calibrate it, might be able to trick it into your highest setting actually being a higher temp
2) Replace with a different thermostat
3) Just live with 90f

Yes I am. I know it sounds crazy but when temperatures are over 100 degrees outside it will get way too hot inside. My friend does this and recommended this but I cant get it above 90

That is the limitation for your system.

Set your thermostat to a temperature that is comfortable to you in the RV.
75 degrees is a good start… You cannot “trick” the A/C unit into cooling differently. If your A/C system is not cooling the RV, you can do a few things…
1. Clean the filter(s)
2. While the filter is off, look at the coils/fins. If they are iced up, one of two things is happening… Either the coils are dirty and not enough air is going through the coils so thae are freezing up. Get some A/C cleaner and clean them off. If they are clean and iced up, you have a refrigerant leak. In this case, you will likely need a new unit. Most RV A/C units are not chargeable/repairable.
2 A/C units should cool the RV to 75 degrees without a problem. I had my 34 ft Class A running on one A/C with outside temps over 100 degrees, the RV in full sun, in Florida, in July and kept the interior below 80 degrees the entire time. (The BR A/C took a dump mid trip)
