Since your Duo-Therm 59516.331 is clean and this isn't an overheating issue caused by debris it sounds like your condenser is going out. When you say blowing warm air if you mean it's hotter then the air outside you're describing the condenser overheating and the fan is still running but blowing all the hot air off of it into your RV. This is definitely a sign of the condenser going out and these breaks between running are going to start getting longer until the unit won't kick back on.
You'll need to replace your AC unit but the Advent Air RV Air Conditioner item # ACM150 will allow you to use the rest of your components. Since yours has the heat pump and furnance you will need the Adapter Wiring Kit for Advent Air RV Air Conditioners item # ACCOLKIT, which will make replacing your Duo-Therm 59516.331 a plug an play installation.

Thanks Jerrod, This isn’t blowing super hot air, just warm air.. I’ve started leaving it within 10 degrees of ambient outside temp when starting the ac unit.. and it seems to cycle on cold for longer periods of time.. then it shifts to warm air… then back too cold after some time… but if I set it a 80 when it’s 105 outside it shifts within a few minutes… When operating it blows cold but the cycle of cold warm cold warm makes me now wonder if it isn’t something else…
