How do i fix my fan speed problem. I lost 1 of 2
It may be a defective switch, loose or corroded contact connection point, where the wire meets a terminal. If these check out good, then the fan motor is defective and needs to be replaced with a new one.
My pop up is dripping water out of the ac can I add a longer hose to the unit to move the drip in better place?
The Mach III has very small drain holes in the pan which can be accessed by removing the cover. Mine doesn't have a hose, but it is on a motorhome, not on a pop up. Does yours actually have a hose? If I was going to try this with mine I think I would try to use air line tubing like you use for aquariums and feed a sufficient length of it into the small drain hole to hold it in place. You can probably also get small plastic clamps (think electrical coax clamps or maybe 3M command widgets) to hold it down so it doesn't come dislodged. It won't cost much to try this theory, but you want to watch that it is draining properly, because if it doesn't then it will leak inside through the gasket.
Compressor won't kick on
You should be able to hear the compressor kick in. If you don't the most likely culprit is the capacitors. I generally keep spare capacitors on hand at all times, because they are mostly likely to fail on a holiday or a weekend when it is 102 in the shade. If replacing the capacitors doesn't work, you want to look at the thermostat. You will have to look up manuals and testing for your thermostat. And if those things doen't solve your problem, sadly and lastly, you will want to do troubleshooting on the control module in the ceiling. The control module generally resides in the ceiling and you access it through the vent in the ceiling.

If this is a park model trailer like mine, there is a transformer in what they call the ceiling package. It is mounted up inside the return air plenum.

You will need 12 vdc (battery or converter) for controls to work, and 115 VAC (hydro) for fan & compressor to work. With your fan obviously working, that tells me you have both already but compressor may not be kicking in. Do you hear a "moaning" sound or see lights dim when switched to cool?
The unit seems to work but doesn't get very
Hi fionajcamero...
I does not make a difference on the electrical plug how you plug it in.
Your problem is low on freon, have the level of (gas) freon brought to the right pressure and your cooling problem will be gone.
You may have a minor leak allowing the freon to escape, have the system checked for a leak.
