When you face a case of rv air conditioner not blowing cold air, it is important to keep in mind that Roof Ventilator air conditioning unit consists of many components, chief among these is the compressor. An RV AC’s compressor is the one element to the system that is not serviceable; meaning, if this component is to sustain some damage, you need to consider replacing it with a new one. You may try to attempt to fix a damaged or broken compressor but the result may not be reliable and to still use it means you have come to terms with possible risks.
How Do You Deal With an RV Air Conditioner Not Blowing Cold?
However, there are elements in a Roof Vent AC that indeed can be serviced, commonly are external to the system, which can be explored when you need to fix the problem. But you have to understand first that by installing a roof to air conditioner unit, you are served with one major compromise. Both the supply and the return air are routed to the same channel: a cutout in the roof measuring to 14” x 14”. As such the distance between the flow of return and supply air is fairly close to one another. This is a very inevitable drawback, which will be made worse if the paths that the two types of airflow are not sealed apart properly.
So perhaps the case of rv air conditioner not blowing cold air that you have in hands right now stems from this mix-up—the return air circulates back in through the supply air’s handle. How do you know if there is a leak? Try to check for cold airflow by placing your hand over the duct where return air flows out. Do this with extreme carefulness. If you can detect cold air flowing through, proper sealing may need to be implemented to prevent more leaks.
Your RV AC unit should come with filters that are washable. These filters can be clogged by dirt, especially when your unit is working throughout the day—in which case, cleaning in weekly interval is necessary. As the filters are washable, you can either vacuum the dirt off them or simple put them in the sink for rinsing. And don’t forget to also clean the evaporator coils because if the filters are dirty, these coils are too. Be mindful of the way your unit blow out and draw in air; is it through the back or the front?
Find out if the case of rv air conditioner not blowing cold air that you face has something to do with its compressor coming off. But if after checking out you find that it’s turned on, then, it might be something to do with either relay board or thermostat. Don’t forget to also check out for its voltage. Most RV AC units won’t work properly with a voltage of 110 or less than that. You also need to maintain perfect airflow from outside and to inside of the room. The outside part of the unit is called condenser and it may not be blocked by anything, such as leaves, as this will prevent it from giving enough heat to the air outside.
