Check the temperature control and see if it clicks when you turn it off and then back on. Check to see if the compressor is running. If the compressor is running but not cooling you may have a leak and lost the refrigerant charge.

You will need to add a self tapping port to the suction side of the unit. You will have to determine what the size of the pipe is and then go to a local a/c supply company and buy one. It's kind of like a self tapping supply for water but for high pressure. Hope this helps. I would also put one in on the high side as well so you don't blow the valve in the compressor if you over charge it or the system is dirty.

It probably has a clogged condensate drain. Take off the cover on top the RV and check hoses or tubes leaving unit for debris or lint. Often this water is used to help cool the condenser so look for leaves pine needles etc in the pan. There may be a cover you can remove on the evaporator section that will allow you to clean the collection pan and hose or trough. Is it possible the RV is far enough out of level that the condensate can't "run uphill"? Always power off while working on this unit unless you are electric savvy. Good luck!

I believe this code is for the outdoor coil sensor not reading or out of range. Check the sensor in the outside unit to see if on of the wires broke or came off it should be located in the outside unit on one of the copper lines near the bottom. If you look through the grill on the outside unit you should see it.

SOURCE: odor when air conditioner turned on

Hi, If its a smell other then electrical burning, I would say it is coming from the evaporator coil inside. Take out the filter and clean it if it is the washable type and try and clean the coil. They make coil cleaner you may be able to get at your RV dealer to do this. This is the only thing I can think of that would have any odor. Unless there is something outside it is drawing in. The system is sealed and would not emit any odors other then a hot motor. You can check up top by removing cover to check the motors and to see if any critters have crawled inside. Let me no, keep me posed on what you find and if you need more help.

PS Check the indoor blower motor also, it may be getting hot and ready to fail.
