Question about Dometic Rooftop RV Air Conditioner

1 Answer

Overloaded generator I have a Dometic CAL 130 A/C which operates perfectly on 240V Mains supply, but when using a Honda EU20I generator the A/C puts the generator into overload mode after operating for 10-20 minutes. Using a clamp meter the A/C runs at 4.6 amps but when the problem occurs the meter amps up to 14.6 amps and the generator goes into overload mode. I was advised to change the thermostat which I have done, and it made no difference, i still have the same problem. Can someone please advise whats going on, as Dometic can't help me. The generator and the A/C have operated okay for the past 8 years, until this current issue.

Honda EM5000SX generator - will not idle up when a load is placed on. Will produce power but will not idle up.


from your description and what you do , the problem is in the auto control unit
it will be in the system to reduce the rpm to idle when there is no load ( auto mains on off controller switching between genset and mains supply)
by turning the auto operation off you are committing the gen set to full rpms regardless of the power requirement
you have the option of having it fixed at an gen set repair shop or leaving it off and starting the genset only when you have a mains power outage
check with an electrician to ensure that it is possible to run it that way as if the mains power unit is not correct , when you start it and you still have mains power , it will destroy the gen set

The device clearly states "AC ~ 220-240v", but is it safe to use a 250v cable? We lost the original cable.


A cable rated UP TO 250v (for it's a maximum rating, not a target) will be perfectly safe with a machine operating at between 220-240v

I need to buy a generator for power. What is the watt power of a 32 inch ilo tv.


Hello A 32" TV sill draw about 175W from mains supply. So it is best for you to buy a generator having a rated power of at least 1000W, so that you can use the excess watts for some other purposes too, and the generator will not get overloaded with the use of TV only. Ok

Honda EU30001 generator causes erratic pellet stove operation.


Ok Motors and the like generally DO NOT really go all that well from a generator, what load does the Stove use?, You must add up the cumlitive "Wattages" of ALL things connected, see your generator is about 3000 Watts, 3KW, How much "headroom" is there between the two? Whats supplied versus whats being used? Purely inductive loads, like Motors etc, are less responsive than electronic loads. I suspect that your generator is NOT providing enough current to the Stove, especially when "Other" things are connected. also. Look, if the, any, generator is 3000 Watts really you should only load it up to a couple of KW's, 2.5KW being about maximum. To do what you are doing would require, IMHO, at least, 5KW, to get the "Headroom" of current drawn over current able to be delivered by the generator. Also inductive loads loose heaps of power and actually cause a higher draw. So that your answer, you must use it well, inside it's rating, not right up to the limit.

Honda EU3000i is rated to put out 15A but won't


If you attempt to use a 15 amp generator to power a 15 amp appliance you will have a big problem. Always plan to use no more than 80% of any power supply. You are currently trying to use the absolute maximum power this generator can supply, and it's probabally not rated for that load at continious use. Get a larger generator, or , a very sharp axe.

I hope this information was useful for you.
