Dometic RV AC 1992 vintage low power light?

Off and on I, am seeing the a low power flash under the ON/OFF switch. I turn off the unit when I see this signal so as to not burn out the unit. Is this a 120 volt or a 12 volt condition. Does anyone know how to solve this problem, or know of a manual for this unit that may have that info. Thanks in advance.;-)) Professor BOB

The low power light comes on when voltage drops below 97 v for more than a few seconds. As voltage drops, amperage draw goes up and could trip a breaker or damage the A/C unit.

I suggest a Progressive Industries EMS which is designed to protect against high or low voltage, spikes, and improperly wired outlets. As you have discovered, in many campgrounds the energy drain from everyone's A/C is often more today than the system was designed for. An EMS can save your systems from damage.
