2010 Dutch Aire 110v AC Issues

On 8/8/18, we traded our 2004 Dutch Star for a 2010 Dutch Aire DP. We officially took possession on 8/17/18 after it had reportedly been inspected by the dealer and the installation of several add-ons that we had requested. After the transfer was complete, we began travelling around to different locations. As of this date we have lost 110v ac power 17 times on 8 different occasions. This had at different times of the time, but has not been a daily occurrence. The power will go off and stay off for 30 seconds to 1-2 minutes and the generally restart once or more times before it stay running. The Progressive EMS has given several messages: high ac voltage on L-1 or high ac voltage on L-2, or line frequency high. The odd thing is that any roof airs that maybe running at the time do not always shutdown. Just now had shutdown #3 for today @ 9:45P. High ac voltage shown this time. What I have done the last several days this has occurred is shut off all breakers on the inverter side, wait 30 seconds +- and turn each on. This seems to cause everything to come back to life. Anyone have any clues as to the possible cause(s) or has had similar occurrences.

  • If your EMS believes your input voltage is high or low, it will shut the AC down and then after a while will reset and try again. Have you checked your voltage at the pedestal. You may have too high a voltage. If it is borderline as your post indicates, you can bypass the EMS with the little slide switch on the unit. I wouldn't do this unless absolutely necessary as it bypasses the circuitry on the EMS and surges or other electrical problems will get through. If it is erroneously reading a high voltage when the voltage is normal, the EMS could be bad and need repaired or replaced.
  • You need to get an electrical person with a meter to find out what actually is going on.
