Question about Dometic Rooftop RV Air Conditioner

1 Answer

A/C is blowing out chunks of ice!!!

The fan blows fine, and the ac works fine for about 4-6 hours, but during the night, pieces of ice come flying out of the vents. It doesnt shut off or anything, and if we leave it off for an hour or two it works fine for another few hours. Is this a freon problem? What do I need to have to check it myself?

If it is not shutting off, I would believe that it is do to either a bad thermostat or a stuck relay (probably on the roof unit). Both are relatively cheap and easy. If you have it done by a tech, have slap the gauges on while he is up there to check the refrigerant levels.

There is ice forming on the evaporator coils. This is either from a low freon charge or a leak in the seals or windows and doors. Could also be that the drains are not working and water is building up and freezing

If your coil is freezing at night, it sounds like your getting cold enough at night to have your saturation temperature drop below the design of what the AC is able to do. If it runs all day without an issue and freezes up at night, you need to add what is called an outdoor fan cycling switch. This will turn the condenser fan off when the saturation temperature drops so it will not freeze your coil at night. You need to have an HVAC technician install this. It is not a DIY projuect since it has adjustments that need to be right. Plus, it it's a heat pump, it needs to drop the switch off in the winter.

My ac blows warm air upstairs only but not downstairs in winter


Sounds like you have a zone system? Is it a bypass type? If it is the fan speed of the heater must be to slow to override the bypass damper. Wire the fan to operate at a single speed same speed as on the A/C.

RV AC unit won't cool, blows chuncks of ice


It's most likely an airflow problem, you say you had the vents closed? Icing up is normally caused by lack of load (air flow) or loss of refrigerant charge. Make sure all your vents are open to allow for as much airflow as possible and that your filter is clean. Some units do not work well on low airflow setting when the outdoor temps cool down at night.

AC ran for a couple of hours and started blowing


If it is icing over, it is low on freon. You might have a freon leak if the system is relatively new. It will take a licensed tech to check, fix leak and recharge.

Split system blower not blowing any air on heat or ac


You maybe iced up. Turn of AC turn fan on and wait about 45 minutes. If fan is blowing air out of vents chances are you were iced up. Two reason for iceing up are AC coil dirty and low on Freon. You need a service tech to check your Charge on system. If you can get to the coil to clean it grreat. Spray it with water let it set and brush clean with a toilet stool bruch. It will not damage the coil. If it is to stopped up you may have to have a service tech chemicaly clean the coil. Fan motors do go out. ou realy need a service tech to check this Rusty

My air conditioner will blow cold air for about 3 hours, Then it keeps running but no air is blowing at all. It's done this 3 times this year already. Thanks, Derek


If you live in a climate where temperature drops in the evening and night time hours run the system with the fan in the on position. This will allow any ice buildup on the cooling coil to melt in the off cycle.

The cooling coil is more than likely iced over stopping the air circulation. Put the fan control in the on position and turn the cooling to off. After an hour or so the ice will clear from the coil and air circulation will be re-established. Then return to cooling and leave the fan control in the on position when in the cooling mode. This will provide air circulation to melt any ice from coil during the off cycle.
