SOURCE: will not shut off

Sounds like a stuck relay on the unit itself. Maybe there is a short in the control wire that comes from the thermostat that activates the fan.

The thermostat probably has one hot wire at all times. The thermostat then chooses which wire to send the voltage down based on your selection. One of those wires is probably for the fan only. Make sure that it is in good condition (no bare, pinched or wires)

Try having a professional check that the collant lines have not perished. Also have them check the thermostat and that there is actually gas in the system. The warm air suggests that the unit has no gas.

SOURCE: My Duo-therm Brisk-Air by Dometic rv ac wont cool.(The fan runs )

Usually just listening closely will give you a rough idea where to look for problem. When you have the fan on and switch to cool, (with temperature turned down low obviously) do you hear any type of "moaning" sounds from AC unit, or see lights in RV dim slightly indicating that compressor is trying to engage? Is the breaker tripping when compressor tries to engage? Do you hear a "click" from AC unit when switched to cool? If none of that happens, then I'd start thinking thermostat, or compressor relay. Normally if it's a faulty capacitor, the compressor will try to engage but will make a "moaning sound" and usually trip the breaker due to excess current draw. Someone experience in electrical should be able to test relays etc, but whoever does work on it, should be aware that those capacitors, as well as hydro in general are very dangerous to work with. The ("zap",- Shock) that you can experience from a capacitor or hydro, can be fatal.

Dometec Briskair Duo-Therm Compressor won't quit running


Have you taken return air filter grille down at ceiling assy, & cleaned filter with dish soap & warm water? Check & see if you see little probe sticking out in behind there, and wipe it carefully as well, and make sure it's lined up to sense air flowing through there. Take a flashlight & look up into coils at front for lots of dust on them as well. Perhaps a thorough cleaning of all coils is in order if you say there's lots of dust, as choking airflow off with dust & dirt, will only shorten life of unit & use more hydro than necessary.
