I have a 13,500 Dometic A/C that usually blows cool air but sometimes changes sounds and blows hot air for a while before switching back to cold. What do I need to fix?

Could be the compressor overload on the way out. Or an intermittant temp control. Or it might just be a loose connection at the junction box between the roof and the base.

2014 Dometic Brisk II 15,000 unit won't cool below 88 degrees


Check the unit to see if the outdoor fan and compressor are coming on. If not, check to see if power is reaching the contactor, both the high power contacts and the low voltage solenoid. Some contactors can be manually actuated, and a quick press (with a NON CONDUCTIVE ITEM) can show you if the contactor is engaging. If the solenoid is not working, check the wiring of your thermostat. When set to cool mode, there should be voltage on the solenoid of the primary contactor, sending power to the outdoor fan motor and compressor.

If the outdoor fan and compressor engage normally, then make certain the coils are free of debris and other blockages. If air flows freely and the compressor is running, feel the tubing for temperature changes. One side should grow cooler and the other warmer.

If the compressor runs but there is no temperature change, take your unit to a certified technician to check for leaks and system pressures. Roof top units typically use R22 refrigerant not R134a automotive refrigerant, which require EPA certification for purchase and dispensing.

Dometic air conditioner blowing cool air


When the cooling slows down, but water is still running off, usually something is icing up. You can turn the unit off, and let it thaw, and try again. Sometimes, if the humidity is high, this is more pronounced. It sounds like you are low on refrigerant. That implies that you have a slight leak. You should have the unit serviced, and the leak repaired.

Dometic RM7291L not effectively cooling on 240V but fine on gas


On the back of the unit, at the bottom, there should be a panel that is removable. Inside should be a fan, the condenser coil, and the compressor. The fan has to be constantly blowing air over the condenser coil, to dissipate the heat (which it is essentially being removed from the refrigerator by the compressor)

When the entire fridge stops cooling, one of three things have happened. The fan isn't removing the heat from the coil, or the compressor isn't compressing the freon, or the freon has somehow leaked out of the system. If it is the fan, you have an easy do it yourself repair. If it is the compressor or the freon, you will probably (but not necessarily) need a professional.

Inside the fridge, there is a coil that is cold instead of hot. A fan must continually blow over that one too, to circulate the air over the cold coils. The fan usually only works when the doors are closed, so be sure to have the door switch pressed to "shut" when checking it.

Check those and post back. And, I know... it really is Dometic.


If the problem is the first one,

Air conditioner not blowing cold air. We put coolant with gauge reading 25 lbs pressure. We think the compressor is coming on. The pipe coming out of the compressor is cool but, the air coming into the car...


Is the air actually blowing into the car?But it's just hot?It sounds like your blower motor is not turning to blow air.you have a fuse,check the switch that controls the blower,and the blower motor it self.

Uotside unit blowing cool air but hot on the inside


It sounds like you have a unit called a heat pump. When a heat pump unit is in cooling mode the outside unit blows hot air and the inside unit blows cold air. If the outside unit is blowing cold then the indoor unit is most likely blowing room temperature or warm air. It sounds like the thermostat could be controlling incorrectly or you could have a failed reversing valve which is the device that switches the unit from heating to cooling mode.
