If there is the voltage on the “line” side, test for voltage on the “load” side of the fuses by placing the meter's leads on the load wire lugs. If you read voltage on this side(220-240V), this means the current is flowing through the fuse. If you get a zero-voltage reading on the load, this means your fuse is blown.

37 RV Air Conditioner Troubleshooting Tips - UPDATED
RV Air Conditioner Troubleshooting Tips And Maintenance Guide. If properly maintained, the RV air conditioner units, rooftop or not in travel trailers or any kind of RV, will provide you several years of cooling efficiency.. This article is divided into two segments or parts:
What to do if your camper AC keeps blowing out air?
It's possible your filter or coils just need a quick cleaning. If the AC fails to blow out air at all, check your fan motor to make sure it's working properly.
What to do if AC blows out air?
If the AC fails to blow out air at all, check your fan motor to make sure it's working properly. Clean or oil it as needed. If your AC blows only hot air, it may be a problem with your compressor. You can test the compressor with a multimeter.
Why does my AC smell?
Musty, mildewy smells can result from clogged or dirty components in your AC unit. First, complete the maintenance steps mentioned above if you have not done so recently and clean your filter and evaporator coils. You should also check the evaporator drain pan for clogs, which can cause water to back up and become stagnant (and therefore smelly). If the smell is more akin to something rotten, check that no critters have holed up and died in your AC unit. If the smell comes from a specific vent, check the duct for dead critters. Otherwise, a propane leak or overcharged house batteries can give off a rotten smell that is then circulated by the AC.
How to check if evaporator coil is clogged?
You may have a clogged component somewhere in your system. Start by checking your filter, evaporator coils, and condenser coils and cleaning them if necessary. Check your evaporator coil for ice buildup. If ice is present, run your fan on high (not cool) until it unfreezes.
What to do if AC freezes up?

What to do if you are not overloading a compressor?
Complete the above maintenance steps and clean your unit thoroughly. If this doesn't help, use a multimeter to test your compressor and capacitors.
How cold can an AC unit be?
Keep in mind that ACs with heat pumps typically aren't built to keep your unit warm in temperatures below about 45 degrees Fahrenheit. This is because heat pumps essentially work the opposite way of an AC. That is, they draw heat from outside and use it to heat your rig. Of course, you can see how this becomes a problem in colder temperatures, where there's not enough heat to draw from outside. Your heat pump is perfect for a cool fall evening, but when it comes to the more frigid temps, you'll you'll need to run your propane furnace. Also, don't mistake your heat strip for a heat pump. Heat strips are designed to provide a heat boost, much like a RV space heater (which is another option for battling cool—but not frigid— temperatures). Heat strips are not meant to heat your whole RV like a furnace.
What to do if your AC is blowing out hot air?
If your AC is blowing out hot air, then the first step is to check the thermostat. If however, you set the temperature right and the AC keeps blowing out hot air, then it is possible that the problem itself is in the thermostat.

Why is there ice on my AC unit?
There is Ice on Your Air Conditioner. Although it is not a very common issue, ice can appear on the outer part of your AC unit. The problem itself is related to the Freon levels in your AC unit, but it is a rather easy problem to fix. The first thing you need to do is check if there are any leaks.
Why won't my AC turn off?
If you notice that you try to turn off your AC unit, but it keeps running, then you will have to fix it right away to prevent damaging of the machine or decrease in longevity. There are a few reasons as to why your AC unit won’t turn off. First, it could be a busted thermostat, in which case you will have to replace it with a new one. If that does not appear to be the issue, then the circuit board could be affected, and so you will have to hire a professional.

How to check if a capacitor is bad?
You can check in the non recommended unsafe way but it's going to pack quite a punch and create a big melt down. Take the capacitor out and lay it on the ground and take a throw away screwdriver and jump across the terminals. If it melts down the screwdriver it's most likely not the capacitor. Fair warning don't expect it to be usable after but if it's bad it won't do anything and you have your answer.
How to measure current capacitance?
You can also use the discharge time to measure the current capacitance with just a volt meter. Use a DC power source to charge the capacitor (it is an AC cap, so polarity does not matter). Even several batteries or a wall-wart battery charger although the closer to working voltage that you can safely work with, the more accurate the final result. Once charged, put the volt meter across it (on a high enough scale!), measure the voltage and watch to see if it drops all by itself. If it visibly drops, you already know it is going bad and should be replaced. Also remember that the volt meter itself has some internal resistance and will slowly discharge the cap. To avoid this measure, disconnect, wait a couple of minutes, measure again. Assuming the capacitor holds a charge and that you have charged it up to around 15V, put a 10K resistor across the capacitor. If it is still good at 5mF, it should take about 50 seconds to drop to roughly 1/3 of the original voltage. If it takes less than 25 seconds it is also time to trade it in.
What color wires go to a fan?
Fan has a few wires. Black for high speed if it has more than one red and blue are usually the other speeds and white is common . If you see 2 brown wires that's what go to the run capacitor.
Do you need a 608 for a 5lb refrigerant?
The prob is that you are supposed to have an EPA cert (type1 608 cert for small package units under 5lb) if you are going to be messing with refrigerants. You can get a type 1 online (I recommend mainstream engineering for that... http://www.epatest.com/.. .)

How does an RV air conditioner work?
It works by circulating a compressed refrigerant, which is usually , Freon, through a series of coils and special cooling fins. This essentially exchanges the heat and humidity inside the RV. Though to do it effectively the RV air conditioner’s compressor relies on the fan to blow the cool air across the RV.
Why won't my compressor start relay engage?
Burns, smudges, or debris can sometimes build up on the connections, which prevents the current from flowing through. When this happens the start relay can’t get the compressor to engage. This is a relatively cheap fix if you are near a well-stocked auto parts store.
