I suspect that you have a bad selector switch for the on, off, low fan, high fan operation. If the selector switch is put into the off position everything should stop completely.

SOURCE: dometic duo-therm air conditioner freezing up

Make sure that you are not running the unit on low fan speed. In the warmer months of the year, this will often cause the unit to freeze up due to the lack of air flow through the evaporator. If you are running on high and it is still freezing, then you possibly have a freon leak in the system. The brisk airs are notorious for the capillary tubes in the upper unit rubbing together and developing a small leak. The problem is usually where the two small tubes enter the evaporator housing. Remove the cover and pull the two small lines apart, damage should be apparent if there is any. If not, you may have developed a leak elsewhere and need to have someone check out the system.

Hope this helps,

Jeff

SOURCE: I have a dometic duo therm roof ac unit that is

It is a closed system, (ends are soldered) that said, a heating and cooling guy may be able to install fill valves and re-charge for you, but make sure you get a quote ahead of time. How old is the unit? Not normal for them to need re-charge, and I've seen them work good for 15 years, if maintained properly. Has it been completely cleaned recently?
