I had a problem like this with my HR. The relay for the condenser fan was fried. On mine 40' diesel pusher it was located on the engine side of the condenser back at the rear of the MH. My AC condenser is hinged on one side, so removing 2 bolts allows it to open outward like a door. This allows easy access to the AC relay and to the engine. The folks at Auto, Bus & Truck air conditoning parts, sales & service in Round Rock, Tx replaced the relay and the fried wired. We also noticed that the compressor side gas pressure was running very high. This is usually caused by a stopped up dryer or expansion valve. In my case a simple dryer replacement and recharge did the trick.
