ONAN 5500 Generator Power

We plugged in this weekend (30 amp) and the AC worked great. We got ready to leave, shut down and unplugged. We went to a park for lunch before heading home, the 3yr old fell asleep so I fired up the generator so we could run the AC. I let it run a minute or so then turned on the AC which immediatly went to shed and would not come on. Repeated the process a couple of times to no avail. Started home, about 2 hours down the road and pulled in to get gas. Fired up the gen, AC came right on and stayed on the rest of the trip, 2 hours with no problem. We are new, so I wanted to get a little info on this before taking it to the RV shop....

Help!

What does
went to shed..mean ???
Did the generator quit running?? Was your fuel tank low on fuel?? Pick-up line feeding fuel to generator is positioned high, so as to not let you "run out of gas". Filling tank brought the level of fuel above the "line", enabling generator to get fuel.

Sometimes a voltage issue can cause the Intellitec to not allow the A/C on. Intermittent, weird little occurings, never can put a finger on exactly what, but next time, try flipping off the A/C breakers, wait a minute or two, then back on. It sometimes can re-set if there's a gremlin in the electrics somewhere....

Without knowing more about the situation, its hard to tell. If you have a repeat of this, track the problem and see what situations are duplicate to the original, process of elimination/deductive reasoning is best.

Also, make sure both of the circuit breakers are in the ON position down on the generator.

One more thing, did you have something else on, like the microwave or somthing drawing power? The Intellitec will shed A/C functions if there isn't enough power to go around, power for microwave and other demands in the kitchen...just a thought.

Hope this helps.....

Help!
Not sure what you mean by "went to shed". If the generator shut off it is likely low fuel if near 1/4 tank which is the general shutoff level for generators in RV's (done so they don't suck the tank dry and then you can't drive to the gas station).

If the a/c did not come on it might be that you did not give it sufficient time to come on. There is a built-in delay in the a/c circuit that keeps you from "short-cycling" the unit. In other words if you turn it off and then back on quickly, the head pressure will be high and the unit could be damaged by trying to start so they build a delay into the circuit so the head pressure equalizes. The delay is generally about 2 to 3 minutes and will occur even if you did not run it, but changed from say heat to cool or sometimes even just changed the temperature. I'd give it at least 5 minutes after you set the thermostat to cool and set the temperature. If it still doesn't work then that is not the issue. Some power conditioners/spike unit also have a built in delay (mine is a progressive and I set it to 3 minutes to allow generator to warm up) so the delay could be as much as 5 minutes before the a/c starts.

Shed means his Intellitec Electronic Climate Control (power management) light was staying red and would not allow the A/C to come on.

This ECC/Intellitec system 'SHEDS' power when necessary and doesn't allow both air conditioning compressors to come on at once. That's how a 30 amp coach can run 2 air conditioners with this system.

Hope this helps...

Mine sometimes goes to shed upon first turned on for one or both AC units. Usually After awhile (few to several minutes) they un-shed. Occasionally one remains in shed. I turn both off, wait a few minutes, then turn them back on and all is well. I think this is common behavior and not a problem per se.

First of all, if you had the generator running but no AC, you don't have a fuel problem. If you had no fuel the thing would not run. The most likely problem is the timer in the changeover box. There is a timer that will not let the generator come on line for about two minutes. This is to allow the generator to come to power and stabilize before you add a load to it. It is very common for these to get weak and not work every time. My coach does this once in a while. I simply shut down the generator and restart it. You can replace just the timer module if it gets really bad. I just live with it because it only happens a couple of times a year. The shed system works on 12 volts, so it will show shedding if there is no 120 volts.
To see if this is the problem, the next time it happens, look at the microwave and see if you have 120 volts. I believe you will see there is no incoming AC.l

I knew you'd know the answer!!

We had over a half tank of gas, while the generator kept running, the "red" shed light on the intellitec dashboard stayed illuminated.

Kent, thanks for the pdf, perhaps I did not give it time to kick in. I will try your ideas next time out, Thanks!

My Fleetwood is of the same era as yours and the Generator is the same model.

As Ga Traveler stated: There is a delay prior to the AC starting after you start the Generator. This seems to be longer when you start the Generator with the AC in the "ON" position. Try to get into the habit off turning the AC off and leave the generator run a couple minutes prior to turning the air on, works for me.

I would think the OP has a 50 amp coach since he says the generator is 5500 watts. Maybe wrong, but that's what mine is.

the OP's first line I just automatically thought he had a 30 amp coach. But maybe only 30 amp was available to plug in to. Didn't think about that.

We plugged in this weekend (30 amp)

Yeah, it was confusing. It's good he has an EMS for times when 50 amp is not available. I don't have one so when plugged into less then 50 have to be mindful of what is being turned on.

His coach is a 30amp coach.

My '97 Bounder is 30amps and it too has the 5500 watt generator.

The ECC mentioned is NOT an EMS. It is only concerned with the two air conditioners. It will not "shed" any other devices or appliances.l
