I just bought a new...
I just bought a new 31-ft Airstream trailer with 2 Dometic air conditioners on the roof. The larger unit--over the living area crapped out this afternoon in SC's 98° temperature. The digital controller gives an E7 error message. Of course, there no clues in the manual and apparently you have NO emergency phone numbers.

At least tell me what the E7 message means? My name isXXXXX XXXXX
Hartsville, SC 29550
XXX-XXX-XXXX.

And I registered both units model & SNs. So they should be in your computer

Hi: Thank you for coming to Just Answer with your question. My name is XXXXX XXXXX perhaps I can assist you with this issue.

 

Were you using any kind of adapter on the shore cord? And we aren't with any dealer or manufacturer here. We are independent repair techs.

I was plugged into 50 amp service, but I use a surge protector? Would that have an effect?

I just responded that I was connected to 50 amp socket but I did have a surge protector between the shore and 50 amp connection.

RV Mechanic: Randall, RVIA Certification replied 10 years ago

No...........that won't affect it. An E7 error on that thermostat is for a power interruption.

Did you try to reset this according to the manual? That should clear this.

The manual says nothing about reset button, but my previous Airstream/Dometic AC/HP had a reset button on the unit itself under the shroud. Is this where the reset button would be.


 


I reset the CCC 2 thermostat inside the trailer but the E7 message remains when I try to restart the unit. Also, the fan only position does not start the fan either.

RV Mechanic: Randall, RVIA Certification replied 10 years ago
It isn't a reset button..........but, a procedure and it will be in the Owner's Manual for this system. And you should be able to unplug the thermostat for a few minutes and plug it back in and then you can reset it. I am on the road and won't be able to access that until I get home tomorrow.

A bit more information. The unit is a 15,000 BTU, Penguin II model with a digital CCC thermostat with 2 zones. Zone 2 (the bedroom) works fine. With Zone 1 (the problem child) the digital unit works okay. Select Cool and the hourglass appears and after several minutes it goes to E7. When I select FAN, I can choose auto, low, medium or high and nothing happens.


 


As you recommended, I disconnected the thermostat from its phone-like connection and waited several minutes. The same results as above. I await your expertise tomorrow.

RV Mechanic: Randall, RVIA Certification replied 10 years ago
Check the power to that A/C unit...........it may not be in the thermostat, but in the AC power to that A/C unit. If you have a small multimeter you can check this fairly easily. Is that the only AC feed that is a problem? Start at the breakers first. Let me know what you find. I am going to be home tomorrow afternoon and will be around all the time.
