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.
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.
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.
Here is where you can find manuals for your a/c unit. Click on the links under the tab for technical information.

Thermostat
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.

Sounds like possible fan capacitor failure. If your not familiar with capacitors, please find someone who is, as they can give a fatal electrical jolt if not handled properly.
Why is my coleman mach squeaking
Our AC did this and needed bearings replaced. Cost $10 dollars to fix it. Husband did the work. Took him less than an hour to replace the bearings.
How many watts is a coleman super mach
Specifications are listed below:http://www.mycaravanparts.com.au/products/appliances/air-conditioning/coleman-mach3.aspxBear in mind, this A/C unit is made for Recreational Vehicles with a Heavy Duty Battery to power such devices for a short time and external power supply for extensive use. The watts listed in the specifications refers to cooling and heating power in watts, British Thermal Units (BTUs) was the old measurement term. Do not confuse these cooling and heating watts with the amount of electrical power consumption in watts. The two are unrelated. Power for this RV A/C unit comes from a battery or external RV connection point. Hopes this helps you.
