If the unit is not ducted, the evaporator coil drain pan sits under the coil and shallow channels in the unit that allow the condensate to migrate to the condenser coil which has a splash ring on the condenser fan blade, that ring slings the condensate upon the hot condenser coil thus evaporating the condensate while help condense and sub cool the refrigerant, very often the channels are clogged with the results of condensate and dust etc accumulating, the evaporator coil itself also may be dirty and obstructed restricting the air flow across the evaporator coil
thus resulting in a low load upon the evaporator coil and icing which will cause dripping, simply being dirty will do it as well it really has to be seen to be sure exactly why your units leaking and from where, rarely they do rust out but it happens.

Remove the lower assembly and tighten the bolts that hold ac down to coach or pull shroud and check to make sure unit is not frezing up due to dirt

I have a Dometic DuoTherm ac/furnace unit in an rv. The thermostat got knocked off the wall and now the ac nor the furnace will work. Fan works in manual position only. What could be wrong?


When the thermostat was knocked off it may have damaged the wiring. I would start by checking continuity of all wires from thermostat to unit.

I have my dometic Rooftop ac unit. The heatstrip/fan run perfectly but when I turn on the ac...the fan runs good but when the compressor kicks on it just hums.


The compressor coming on does make a slight "humming" sound which is normal. Is the unit cooling properly? Do you think it is louder than before?

Dometic Duo-Therm air conditioner: keeps tripping the breaker. Unit is 4 years old. 57915-331 Everytime we use it; it cools the camper just fine but out of the blue it trips the breaker and won't work....


First clean the condensor with air blower or water pump and clean the filters.If the same problem persists there is a choke up in the refrigeration piping, cut from the discharge side and suction side flush the system with nitrogen, replace the filter drier and choked capillary if it is a capillary system, brace back the discharge and suction piping to the compressor again, leak test with nitrogen, evacuate the system charge refrigerant and start the system.
