I have the 13500 btu rooftop and want to know is there only one capacitor in this model and where can I buy capacitors?

relay board bad.

If you Google airxcel.com, you should get some options. to get either their literature or tech support and they should be able to help you.

the hard start kit wont harm unit but you need 3500 watts for one a/c

No, the capacitor is not integral to the load of the generator, it is only used to start it when it turns on. It takes virtually no voltage from the system to recharge itself. The demand of the unit is not related to a start capacitor. Also it will not harm your unit to install one capacitor over another, they make them so if the connectors fit, they work. Just hook up the leads correctly so you don't discharge it on yourself.

Sounds like it's low on refrigerant, if you haven't used it for a while they normally leak at the compressor shaft seal

Good possibility it has a fan capacitor gone, but a voltage/ohm, check would be required, and if your not experienced in that area, can be VERY DANGEROUS, if you don't know how to handle them as capacitors can zap you with high voltages (approx, 370- 450 volts) even when disconnected from power. If you know an electrician, that would certainly help.

Buy a new one. Your repair will cost approx 2/3rd (or more) the price of your new unit. Your old unit has no warranty left while your new unit will have a warranty. :-)

Your choices are another Dometic or a Coleman
I prefer the Coleman But the amount of extra cooling you will get by stepping up to a 15K unit will probability not be worth the added cost

It was quite simple, just installing the heat strip and my model only required removing the grill cover and mounting the element. The other optional installations didn't apply to my model.

thanks,

I have a dometic 13500 BTU Roof mount a/c. It is set up with the duo-therm analog thermostat. The system cools fine. The problem is that the a/c gets down to the right temp, then it turns off like it should but turns right back on within a few seconds. Any help would be greatly appreciated.
