2016 Classic Air Conditioner Problems

We bought our Airstream the end of December. We are now on our third microwave and as of today our rear air conditioner has gone out again so this will be our second air conditioner. Would you assume this sounds like possible wiring problems? The breaker was changed on the microwave but not the air conditioner. We have noticed that no condensation is coming out of the rear air conditioner hose, which we have checked the hose for blockage. We're stumped!! Tomorrow morning the RV park will be checking to make sure the electrical box outside is actually pulling 50amps to rule that problem out but we are 90% sure that isn't the problem. Has anyone had these type of issues before and if so what did you do?
Thanks in advance for any help possible. We're new to RV life and we really don't feel we should be working out these kinds of bugs within the time we have had our new, straight from the factory, Airstream.

I certainly am no expert on this matter but, my thoughts are that low voltage and/or power surges may be at fault. Are you using a good surge protector? The more sophisticated models guard against low voltages as well as surges.

Sorry to hear of your troubles. Hopefully you will get to the bottom of this soon.

Thanks Ron,
We will look into this tomorrow with the RV Mechanic.

I'm with Ronald on this. My first action would be to acquire a quality surge protector with both low (the more likely culprit in the failures you've experienced) and high voltage protection. A decent protector should also look got open neutral, hot/neutral reversal, open ground and other all too common wiring issues found in campgrounds.

Be sure to use it even if you are on generators of your own, not campground power. I am much more likely to see low voltage from my own generators than from shore power.

No problems with our 2016 Classic

We are full-timers living in our Classic and have not had any electrical issues despite traveling and staying in a variety of RV parks, some with poor, uneven power delivery. We bought the best surge protector we could find prior to taking delivery of our AS. Maybe that has helped us avoid any issues so far. Good luck and we hope you enjoy your Classic!

Monitoring the incoming voltage for a voltage drop will determine if the source of power has enough current. Check the voltage with no or minimal load, and compare that to the voltage when there is full load (i.e.: both AC units are running concurrently). You should not see a significant voltage drop. If you do, then your problem is likely the >source< of the power.

You can also compare the voltage coming into the trailer under load and compare that to the voltage going in to the A/C unit itself. Again, there should not be a significant difference. If you see a significant drop there, then the problem is somewhere within the confines of your new trailer.

"Surges" are a bit of a misnomer here. The key is monitoring for voltage drops due to poor connections or the wire being too small for the load. Wire getting slightly warm is not abnormal.

Having multiple digital multimeters, or one that will record a MIN / MAX, will assist in the troubleshooting. This same procedure can be used for checking and comparing the voltage to the microwave as well; look for a difference between the voltage coming in to the trailer versus the voltage at the receptacle that the microwave is plugged in to.

I have a new 2016 Classic. We have about 7 weeks living time on her and have had no electrical issues whatsoever. You may have a single loose connection causing a voltage drop that is responsible for all of the issues you have been experiencing. The procedure I have outlined will help narrow down the location of the fault.

since you are still under warranty what is the dealer saying the issue is.. Might need to make at trip to JC to get it right. Something is going on it seems.

good luck.

Does anyone know id the '16 classic has a built in low voltage and surge protector? I don't think the owners manual says id It does or not.

I am not aware that Airstream put voltage or surge protection in any of its models, in any years. We have had to buy that aftermarket.

No surge protector in any Airstream. But, a number of people do add them inside the trailer. We use a Progressive on the outside for some time now and so far so good.

A couple thoughts ...

3 Microwaves in a few months (assuming you mean you bought a used or leftover 2016 in Dec 2106) is extremely unusual. While it could be power issues, I would make sure that it is not an operational issue first. All of these convection microwaves are a convoluted to operate in convection mode, and I have known more than one person to fry one thinking they are in convection (with a metal pan in there) when they were in microwave mode instead. Your description of what happened is a bit brief, but the usual issue with very low voltage is pulling high current that destroys something due to resistive losses - that also often results in the breaker tripping if the appliance is not on a circuit with substantial over-capacity (10A load on a 30A circuit).

Almost everyone I know (myself included) had AC infant mortality with the smaller 11k BTU units on 2016 FC and Classics. They were all coolant leaks - the compressor and fan ran normally, but no cool (or warm in HP mode) air came out.

One great reason to use something like the Progressive Industries power devices is they kill the power below 106 VAC (might be 108 - don't recall) so you don't damage an AC or other appliance. They also have low voltage reporting.

Don't think this is your problem but wanted to also remind to always turn the breakers on the outside power pole off before plugging or unplugging your trailer.

Also, make sure all appliances like hot water heater and a/c is off before plugging or unplugging.

Sure sounds like you have a power source issue to others said get you a surge protector...and move to another rv park!

We were winter camping one year in our Classic and we went from having two AC's w/heat pumps and a furnace down to only one working AC. We were lucky in that the night time temps never went below what our portable heater and remaining heat pump would provide. I spent the next year looking for my problem. At one time replacing the control card in the front AC unit which controlled all three units. Still no success. I finally found my problem when I started to examine ALL exposed wiring I could get to. Problem was a loose electrical connection on the natural side found in the rear AC unit. You could see where it had arched inside. Repaired the connection and everything started to work again. Sometimes the solution can be very simple. It just takes time to uncover the problem. Wish you luck in finding your problem.

I'll guess you meant to say "Neutral".
My house had flickering lights for a while. I thought it was my very old wiring but I called the electric company and the lineman found a corroded neutral on the transformer outside. It's more common than you think, you did a great job of troubleshooting!

If the original poster experienced three microwave failures and they weren't all in the SAME RV park, I'd look to wiring. Remember, the appliance will draw (let's say) 1000 watts. If the voltage drops, the current increases to make up the difference. That kills motors, etc.

We also have a 2016 Classic that we took delivery of in December 2015. We also had a failed bedroom a/c, but I don't think that's particularly relevant here. BTW, we always use a PD surge protector at the post.

We had a myriad of electrical issues (a microwave that would work one minute but not the next, GFCI tripping all the time). Then one day our factory converter failed and we replaced it with a better one.

Since then, no microwave problems or GFCI trips or other electrical anomalies.
