6 Common WFCO 9855 Converter Problems (Troubleshooting)

WFCO has been the standard-bearer for many years regarding reliable power products for recreational vehicles (RVs).

Some of the power products they provide are inverters, energy management, transfer switches, WAGO connectors, power centers, and innovative lithium-ion devices. The WFCO 9855 Converter, which the company just released, has caused quite a stir in the industry.

These converters have a stringent performance and a long life due to the lack of mechanical moving parts, provided they are used within their rated limits.

However, you may encounter a few issues while using the WFCO 9855 converter. In this article, we’ll go over some of the most frequently encountered problems and the solutions to those problems. Let’s delve even further into them!

WFCO 9855 Converter Problems

1. Check Battery

There have been many complaints regarding the battery. So, if you’re having problems with your converter, you should start by checking the battery.

If the lights are dull and flickering continuously, it is an indication that the RV isn’t getting enough juice because of an underlying problem.

The batteries are responsible for providing the current to your RV that it needs to run electric appliances. Before doing anything else, take out the RV’s batteries.

Verify that every connection has been cut. If you have a digital multimeter, you may check the battery voltage by connecting it to the batteries. Be sure to check every battery if you have more than one.

They require a consistent voltage of 12.3-12.9 V. As quickly as possible, if it drops below that mark, you should have it fixed, or else your RV and any electronics plugged into it won’t get power.

If your battery isn’t holding its charge, try filling it with water. If there are any oxide coatings on the connectors, you can wipe them off and restore proper function.

They typically come in shades of gray or blue. Try soaking them in warm water if you’re having difficulties removing them.

Water shouldn’t be poured directly on the device; a wet cloth should be used. If the issue persists, it’s likely due to low battery power. Therefore, you’ll need to have them replaced with new ones.

2. Check Internal Components

The WFCO 9855 Converter has many components, and when any of them fails, it may cause problems. So, consider checking the circuit board and other components, such as the fan, temperature sensor, and load sensor.

Inspecting every component can be time-consuming, which is why it would be a good idea to hire a technician to get them checked.

In many instances, replacing the entire power converter is the only long-term solution if multiple components have gone bad. Be careful when handling the power converter since it has electrical connections and a sensitive circuit board.

3. Check Fuse

If your battery is functioning correctly but your converter is not, the problem could be with the fuses. If the current value begins to fluctuate, these will burn out. You will need to check the fuse to verify whether it is causing the problem or not.

Disconnecting the unit is the first step in checking the fuse. After that, locate the fuse and visually inspect it. If it has blackened, replace it with a new one.

These are widely available and may be bought from any electrical retailer. However, they must have an identical voltage rating. The rating is mentioned on the package to avoid any confusion.

4. Check Converter Fan

The fan on the WFCO 9855 converter is responsible for cooling the inside components. If the converter fan stops working, the converter can overheat, ultimately leading to failure.

You can use a multimeter to identify whether or not the fan is getting power. The fan fails if it is connected to a power source but does not turn on.

Simply replacing the fan is an option, but the problem can be salvageable in some cases. Oftentimes, the problem is with the motor. So, replacing it will likely do the trick.

5. Check Circuit Breakers

Sometimes, the problem could be as simple as a tripped breaker. If there are power outages or other electrical problems, these can be tripped. If this happens, you’ll have to turn them on again manually.

Keeping this in mind, examine the converter’s control panel to determine whether or not the circuit breakers are functioning correctly. To get the connection back up and running, simply reset the breaker.

However, there may be occasions when these require replacement, as well.

Last but not least, using the original adaptor can help you avoid similar issues with the converter. Many people instead use third-party accessories that increase the possibility of voltage rating fluctuation.

6. Check Temperature and Load Sensors

The heat generated by the converter is monitored by a temperature sensor, which then sends a signal to activate the fan responsible for cooling. The fan is kicked on by a load sensor.

These sensors can malfunction, and when they do, the fan will not be signaled to start when it is supposed to.

Verify that power is being given to the sensor, and then ensure that power is transferred to the fan. For this purpose, you will have to check the wiring. If the wires are damaged, get them replaced to resolve the issue.

The Bottom Line

The WFCO 9855 converter is a go-to choice for many, thanks to its exceptional performance. However, it is also susceptible to malfunctions, just like any other electronic gadget.

If you face any problems, we have mentioned simple fixes that you can try at home. Regular maintenance is recommended to keep your RV converter up and running.
