Unhappy AC E1 code I NEED SOME HELP

Just bought a Prime Time Crusader last month. the night I bought it the outside temp was around 92 F. The RV has a digital comfort thermostat. It has 4 zones of which I only need 2. I started both ac units as directed and went to dinner. came back in an hour an the thermostat had a E1 error code showing and the AC's had quit producing cool air. I was able to get the main ac to run and cool for the night. I returned to the dealer the following morning to have them check it out and no problem was found. the said it may have been a 50 amp power problem.
15 days later we went to a campground near our home and the same problem happened. E1 code. I checked toe power and there was 50 amps. the outside temp was near 90 F. I checked with Dometic and I was sent to a dealer that was authorized by them. the problem could not be duplicated.
Called Dometic again and they said there was a problem with the ducting on my RV.
I NEED SOME HELP. I paid a lot of money for this RV and would like to have it fixed. Anyone have any answers.

You don't check the amp you need to check the volts. Aside from that an E1 is a communication error. You might want to check all the connections and make sure they are all good.

The E1 error on the thermostat is a communication error between the t-stat and the control board.

It could be either the thermostat, one or both of the control boards, or the cable itself.

The communication cable is connected using an R-11 phone plug. I'd try unplugging the plug out and looking at the spring contacts in the jacks and if they look good plug and unplug the plugs a few time to clean up the contacts.

After that, initialize the thermostat as outlined in the manual.

If that doesn't fix the problem, you either have some bad wiring or a bad control board.

I don't have a clue why Dometic told you that you had a problem with the ducting in your RV, or how they could possibly know that.

I was thinking he same thing

Thanks Bama Rambler,

I took it to a dealer here that is authorized to work on the Dometic and they told me they could not duplicate the E1 error.

I would like to get a number for Dometic that I might be able to talk to a Tech rather than a customer service person.

The voltage and amps are good at the park and these units SHOULD run ok in HOT weather. Don't you think?
Any Ideas?

They absolutely should run well in hot weather. In fact there are many, many of them that do.

I don't have any contact information for a Dometic tech. You could ask customer service to connect you with a tech. I'm not sure they will, but you never know unless you ask.

Just for grins you may want to look in the duct work. I took my phone and stuck it up in the registers once I pried them off and took pictures both directions. You can see some of the pics I took in my 'Bama's Ramblin Mods' thread.

I had a similar problem. The wiring was hung up inside the wall. Dealer got permission to open the wall and got the problem fixed.

I had the dreaded E1 error the day I brought my 5-er home. After A LOT of research, I found three things involving the thermostat.
1. Disconnect all of the power in the RV. That means unplug it from shore power and disconnect the battery. Let it sit for 15-20 minutes.Reconnect the battery, plug it back into shore power, and reset the thermostat (following the process called out in the manual). It should now work.
2. Each time you are taking down camp, ALWAYS set the modes to off for each zone, and then turn off the power to the thermostat before you disconnect shore power.
3. The sensor in the bedroom was 2 degrees off. The actual temperature was 2 degrees higher than what the sensor thought it was. We set the temp 2 degrees lower in that zone and now everyone is happy.

Lastly, it was having trouble staying cool in very high outside temperatures. I looked in the air returns and found that one had some of the reflective foam sagging across most of the duct. I placed a small piece of wood in it to hold up the foam and have had no problems since.

That thermostat design and communication scheme by Dometic was absolutely terrible. If you look at the forums, that error code comes up almost as much as people complaining about Camping World.

We haven't seen the E1 since I performed the original power-down reset. I hope it never happens again, since there is no other real fix, except to replace the entire thing with a different brand and I don't want to spend $1500 to do that.

E1 code problem fixed

I just had the E1 code. Took the unit to Total Value RV in Elkhart, and they quickly figured out that they had to replace both of the RJ11 plugs in both AC units. As soon as they did that all AC worked good. They identified that the problem was a communication problem between the AC unit and thermostat.

If that would not have worked then it would need to replace the control boards, thank goodness that didn't happen

Hey bhumphr196,
Thanks for that info. You're the first I've heard of that has had the RJ-11 plugs replaced. I've suspected bad crimps in a few of these errors we're seeing, but no one has reported replacing the plugs.

Hi, I had the E1 code numerous times. I replaced the RJ11 couplings, recrimped the male terminals, tie wrapped the cables to ensure tight connection, silicone the ends to ensure no humidity gets in. NO MORE E1 OR ANY HICKUPS!
That being said, my wife and I have a 2014 Spartan toyhauler and lately the problem is poor return from the "return ducts" if you consider a 3/4 inch high bu 8 inch wide passage a return duct. This is highly restrictive and not suitable for a 15000 but hair conditioner. I am considering cutting the ceiling and installing a third return grill with an adequate filter under the return opening of the unit. The negative pressure also interferes with condensate drainage as well as cooling capacity.
