2. The Device Won’t Stay On

Another common problem people face with the Onan Microquiet 4000 is that the generator refuses to stay on. This situation can be frustrating because you rely on your generator while camping to provide electricity to your appliances.

When your generator does it stay on, there’s no way for you to run your appliances safely. There are a few different reasons why your generator might not turn on that we will discuss below.

How To Identify

If your generator keeps turning off, it could be due to overheating or too much dirt clogging the vents. It’s important to know that this problem isn’t the same as your generator refusing to turn on. These problems have different causes, and the main reasons your generator keeps turning off are the following.

1. Your generator is too close to a heater: Pay attention to the placement of your generator to ensure it’s not near a heating device. It would be best to keep your generator in an area around 70 degrees Fahrenheit. If you keep your generator next to a hot surface, it will overheat and refuse to stay on.
2. Your generator is crowded: It would be best to keep it in a wide-open area. Unfortunately, RVs typically don’t have much space, so letting things pile up around your generator can be easy. Keep clutter as far away from your generator as possible, so it continues to run well.
3. You haven’t cleaned your generator in a while: Some people don’t realize you’re supposed to clean your generator once every six months. If you don’t clean your generator enough, dust particles will build up on the surface and inside your device, making it difficult to run.

No matter why your generator won’t stay on, it’s easy to resolve this problem. The fact that your generator turns on in the first place indicates no hardware problems to worry about. If your generator keeps shutting off, you can typically resolve the issue without a professional.

How To Fix

Before you start working on your generator, it’s important to turn it off and unplug it from the main power line. You don’t want to put yourself at risk of receiving an injury while fixing your generator problems.

1. Use pressurized air on the vents of your generator to clear out any dust or dirt
2. Move your generator to a safer location
3. Replace any damaged pipes that you notice throughout your generator
4. Top off your fuel levels

If you feel nervous about tackling any of these problems, you can always bring your generator to a professional for help. You should never tackle a job if you feel unsafe performing the labor. Plus, a professional can help identify if there’s something seriously wrong with your generator.

3. Battery Problems

your generator uses a battery to provide electricity to your RV. You’ll notice several issues when running the device if there’s anything wrong with your generator’s battery. There can be something wrong with your battery connections or the battery itself.

You can also have battery problems if your RV battery starts to go out. Unfortunately, RV batteries don’t last forever, and you need both battery sources to run electricity through your vehicle. The most common issue people encounter with their RV batteries is the battery not charging while driving.

How To Identify

Identifying battery problems with your generator or vehicle is an easy process. Follow the steps below to check your charge and determine if you need a battery replacement or to clean the receptacle.

1. Purchase a voltage meter
2. Check the current on your RV battery
3. Check the current on your generator battery
4. Move on to a different step if both batteries operate well

If you don’t have a voltage meter, you can check your battery by starting your vehicle or running your generator. If either device doesn’t turn on, there’s something wrong with your power supply.

How To Fix

You don’t always have to replace your RV or generator batteries to make the devices work again. Sometimes, you just need a boosting energy source to recharge the batteries and operate them again. The following options will help you repair or replace your batteries with running your generator properly.

• Purchase jumper cables and use another vehicle to jumpstart your RV battery. This will give you a sufficient power supply to get to a better location for a replacement. It would be best to always keep jumper cables in your RV to keep yourself protected from emergencies.
• Check your battery connections in the generator to ensure everything is connected properly. If you have any loose connections, you should tie them in before replacing your battery.
• Replace the battery that is operating well. Unfortunately, there are situations where you can’t repair the battery because they have a set life span.

The Onan Microquiet 4000 won’t work correctly if you have low batteries. You’ll need to check your RV and generator batteries to identify the problem. Only checking one battery could cause you to misdiagnose your generator issues.

Lack Of Routine Maintenance

Whenever you purchase RV supplies, it’s important to perform routine maintenance on all of your RV materials. These materials include the RV itself and your portable generator. The following tips will help you properly care for your portable generator to last as long as possible.

• Clean your generator regularly
• Be mindful of generator placement
• Empty your generator tank
• Replace the fuel filter
• Keep track of your generator battery
• Don’t run too many appliances simultaneously
• Don’t run your generator for too long consecutively

Neglecting to follow any of these routine maintenance specifics could cause you to ruin your generator sooner than necessary. Treating your generator right can make it last up to 10 years or 20,000 hours.

However, if you don’t take proper care of your generator, it might only last a few years before you need to purchase a replacement. When you own an RV, it’s important to take great care of your appliances and energy suppliers to continue enjoying your adventures. You don’t want to end up somewhere and get stuck without electricity.

Finding yourself stranded without electricity can be a stressful experience for everybody on your trip. Take great care of your generator to avoid this problem, so you don’t feel nervous on your next RV vacation.
