It doesn’t matter whether you’re in summer or winter, an AC is a must everywhere. But, it’s really annoying when you turn on the AC and no cold air is coming in. Instead of cold air, warm air comes in which makes things even worse.
What does it mean for you?
Well, the compressor in the air conditioner might be dead or ineffective. Hence, warm air is flowing instead of cold air.
So, what should you do when the RV air conditioner compressor not coming on?
Don’t worry, we’ve got your back. In fact, we’ve compiled some simple methods that you should be doing when the compressor of the AC isn’t working.
Moreover, we even discuss the causes of this problem. And in the end, we have a FAQ session that will clear out most of your confusion about this topic.
So, let’s begin, shall we?
Why Won’t the Compressor of the AC Come Out?
When the compressor doesn’t work in an AC, it lets out warm air inside the RV. As a result, the experience isn’t so pleasant. Moreover, if it’s summertime, you’ll feel miserable as the environment in your RV will be really hot.
However, you should know that when the compressor goes out, the AC works fine. So, in this state, the fan continues to blow only without any coolness.
Now, you might be asking yourself, what causes the compressor to go off?
Well, there can be various reasons why a compressor will fail to come on. Let’s look at some of them:
- Malfunctioned Starting Compressor
About 79% of the time, a malfunctioned starting compressor is the main culprit. Hence, it’s better to check the compressor before buying it. Also, buy from manufacturers that have a warranty on them.
- Dirty Filters
If dirt builds up in the coils and filters, it can cause the unit to shut down. Moreover, a clogged-up filter can reduce airflow in significant amounts. As a result, the coil of the evaporator stops working.
As if that’s not enough, these dirty filters can cause the compressor to overheat. This is because it constantly puts pressure on it. Hence, the compressor shuts down and doesn’t come up.
- Dead Compressor
This can happen when a compressor gets under too much pressure and eventually burns out. Here, overheating of the compressor is the main reason for it to be dead completely.
- Capacitor and Relay Problems
The relays are responsible for the supply of power in the compressor. On the other hand, they’re also the cause of many problems with the compressor.
Again, the capacitors also provide power to run the compressor and the fans. When the problems occur in the capacitor and relays, the compressors shut down and doesn’t start.
Many times, the compressor won’t start because the power isn’t enough in the outer unit. Furnace blower malfunctioning and several major parts of your RV are affected due to insufficient power. However, the fans run normally as the central unit has power in it.
By now, you should know what causes the compressor to not work in an RV. But, it doesn’t mean you can’t fix them. In fact, if you can follow the methods that we’re about to show you now, you can fix this issue in no time. So, let’s see what you should be doing:
The tools that you’ll need for the job are affordable and available. Also, you can buy them from the local markets or online. Let’s take a look at them:

A. Check Power
Firstly, check whether your compressor is getting enough power in it. This is because burnt fuses can easily cause your compressor to stop working. So, if you can make sure if the compressor has enough power in it then it can start working again.
If the fuses are fine, call in a professional. However, if you want to do it yourself, check if the voltage of the compressor is right. Even though you can do all these things on your own, you can still call up a technician to check if it’s right or not.
And the Good news?
Well, this might solve the problem easily. Also, this doesn’t cost much so you won’t have to break your bank in the process.
B. Check the Start Relays and Capacitors
A broken capacitor can cause a compressor to not turn on. So, if that’s the case, you can replace it with a new one.
On the other hand, you can replace start relays easily as well without much of an inconvenience. The best thing about these two fixes is that they don’t cost much and you can get them replaced easily.
Also, you can check the capacitors using a Multimeter and the start relays using a Tester Relay. But, you shouldn’t worry as these tools are affordable.
C. Check the Terminal Connections
Loose connections can cause problems. Like, the main battery disconnect switch troubleshooting or any other wiring issues are common. Hence, it’s essential that you check whether the terminal connections are tight and in place. This can resolve the problem too if you had loose connections before.
So, you can easily check them using the power wires. If you don’t have these tools before, purchase them online.
D. Replace Compressor
If the compressor is completely dead and won’t start, then you’ll have to change it. Even though it’s quite an expensive option to take, it’ll still be worth it in the long run.
