Ac ?

[mjc29]

In my 08 Seneca my AC failed last night. It was running and my Bulldog shut off with an E4 error over load on leg 2. Does anybody here know more about these things, since it was already running I don't have a startup load problem. Do the compressor just fail? I will have to wait until much later today to get hot enough to get it to try again. So my question is easier to just replace or attempt to fix? And does control box come with new unit?

Did (does) your Bulldog tell you the voltage and do you know what it was? Generally speaking it isn't a great idea to replace or fix an A/C until you know why it isn't working. The problem could be as simple as low voltage in the shore power, or too much load in the RV, or a failed capacitor, and other reasons as well.

What I would likely do first is turn off everything possible and then attempt to turn on the A/C(s) again while monitoring the voltage. ~CA

When you say running, do you mean the fan was on. The compressor cycles so yes it could have just failed. Is it a heat pump unit? If the reverseing valve fails that can also cause the compressor to overload due to excessive head pressure. I don't think the control box comes with the unit. You need to specify non ducted to get the correct one.

I finally got a chance to try and it is working with my generator for now. I didn’t have app working so i am not sure what caused the error. I will monitor for now.

Just for grins, make sure the plugs spades are all clean and shiny brass. Had one plug that was darker, and copper looking and was getting an occasional error. Cleaned them all with some emery cloth and good so far.

This has happened to us many times. What happens is you have an overcurrent, and the EMS shuts you down. Then you whip out the app, see that it's an "overcurrent error", and punch the reset button. It closes back and allows power into the rig, but the cause of the initial overcurrent is still present, AND the AC unit(s) are trying to kick on, and you hit the error again almost immediately.

So when your power shuts off, the first thing you need to do is check your EMS app to see why (if you don't already know, more on that later). If it's overcurrent, go around and turn off all your high draw devices (coffee maker, ice maker, microwave, AC units, water heater if electric, etc. THEN reset your EMS, THEN go turn on your devices one by one.

The "more later" is that I've literally hit a button to turn something on forgetting momentarily that item will cause an overcurrent. Usually an expletive coincides with the action at the same time, then everything shuts down. I knew exactly what was going to happen when I punched that button, so I'm not surprised and know how to proceed. Usually that process includes a lot of self-deprecating mumbling...
