Dual A/C issue 1996 Winnebago Warrior

I just purchased a 96 Warrior and am having an issue. I turn the generator on and only the rear A/C unit works, the front a/c doesn't turn on. Anyone know what the issue might be or what I can check?

On our motorhome there is 2 circuit breakers mounted on the generator itself that if one or the other is tripped either the front or back ac won't work depending on which one is tripped. Other than that check all the circuit breakers inside. Does the ac work when you're plugged into house current?

Thanks for the response. Both breakers on the generator are fine. Only breaker panel I found inside is under the sink area and it looks as if there is only one 20amp breaker for the A/C in this case, which is fine. I've had other travel trailers, etc, and there were multiple panels inside but only found one here.

I need to get a power cable to plug into my house current and see if there is any difference. It didn't come with one. If it does work when plugged into the house is a leg on the generator possibly bad or is it not pushing out enough power to run both A/C units? I'm guessing one cranks on and then the other after a couple minutes but just a guess. I tried leaving the back A/C off, but no change.

Wait 5 full minutes for the a/c to kick on due to the timer delay.

how big is the genny?
are there 2 breakers on it, a 30 and a 20?

You could have a problem with the 30 amp side of the genny, or a transfer switch problem, or maybe just an issue with the front a/c.

For sure do the shore power test.

I've seen some where "you" are the transfer switch, you actually have to plug the generator in. (or unplug it and plug in the shore power cord.

Do any other 115ac devices in the coach work?

I'm sure you have checked or know this, but just to be sure...on our '96 Brave there is a switch from front to rear AC...it has to be in the front position for both ACs to work.

On edit...it could also be that the rear AC is keeping the temps cool enough that the front AC does not need to come on...perhaps it's just not warm enough for both?

On a lot of 30 amp MHs an Itellitec Energy Management System (EMU2) was installed to allow two roof AC units to be able to run off the generator and only one when plugged into 30 amp shore power. If installed there should be a small black control box with two switches and two red LEDs. The switches are labeled FRONT AC and REAR AC. If you start the generator and briefly push each of these switches once the red LEDs will start flashing red then after two minutes will go solid red and at that time if both thermostats are on and turned to COOL both ACs will start. If you have this little control panel and your one AC is working check and see if you have one solid red LED for that AC unit. If you do then push the other switch until the other AC led flashes and wait two minutes.

Is that a 30 amp rig? On many 30 amp rigs (nd even some 50's) there is a switch "Front/Rear" and optionally "Both" that selects which A/C works. Normally on a 30 amp rig the Genrator runs the REAR A/C directly, (independent of the switch setting) but if the switch is set to REAR the Front won't work, ever.

I believe there is a switch in cabinet over frig for front or rear air when running gen. Select front for both to run.I had a 94 I installed a double pole double throw switch and a heavy duty cord so I could run both airs on shore power.
