Question about Coleman Mach 15 Air Conditioner
When I turn my AC unit on it runs fine and cools down my RV. After 1st cycle the compressor sounds like it is trying to kick in but after about 40 seconds it stops and only the fan runs. About 3-4 minutes later the compressor tries to kick in but the same thing happens. This goes on and on unless I turn the ac unit off for about an hour and then when I turn it on it will work fine but only through the 1st cycle. Do I have a compressor issue? Do I need to buy a new unit?
Take a look at your start capacitor. This the capacitor that kicks the compressor over when it tries to start. If the capacitor is bad, it cannot kick the compressor back over after the first cycle because the head pressure has not evened out yet. It is located in the upper unit on the side panel in a small box. Be careful, highly charged capacitors can zap you if you are not careful. Disconnect power and touch across the terminals with a meter or a screwdriver to discharge the capacitor.
Hope this helps,

What does it do when powered by the generator? Or is this happening with 110? Do you have an invertoer on the system? 12v to 110? The reason is power supply issues. What happens on shore power? Any problems then? Has the unit been serviced or worked on recently? Is the fan outside (condensor fan) working? If it isn't it will cause high head pressures. Go topside and verify it is working, it can relly overtax the compressor.- good luck
