Our Duo Therm Air Conditioner runs fine on high but when you try to turn it down to low or medium it shut off completely and a red signal light comes on with a low power message. If you turn it back up to high it runs fine. Does anyone have a idea of what is going on? We're running it at 30 amps.
I experienced this on my 91 DuoTherm. Replaced caps, motor failed a few months later.
My mains voltage always remained acceptable... 120-128 volts.
Those long shaft motors are difficult to find for those specific Airstream models. A Penguin II might be in your future!
