So, if the power converter fails to turn on, you have to check the wiring connections. The power converter is responsible to ensure the high efficiency of the electrical components and optimizing the battery functions (recharging and supplying electric connection). Both these issues are impossible to fix on your own, which is why we recommend that you hire an electrician. In most cases, the high voltage output is caused by insulation failure or switching pulses. In addition, the high output can overheat the electric appliances, which leads to permanent appliance failure. The high voltage output can cause the failure of electronic components, such as circuit boards. For this reason, it’s recommended that you hire an electrician and ask him to replace the switching transformer. The damaged switching transformers not only cause a drop in output voltage but also cause damage to the switch tube. So, if the voltage output is low, it’s likely that the switching transformers are damaged. The switching transformers are responsible for regulating the power supply and increasing or decreasing the current or voltage according to the power supply needs. For this reason, we recommend that you repair the switch tube. However, if the switch tube is damaged, it negatively impacts the conduction capacity of the switch tube, which increases the power supply’s internal resistance.Īs a result, the load capacity and output will be reduced. The switch tube is responsible for conducting the electric or power signals, resulting in the production of sufficient output. If there is no continuity in the capacitor, you have to get it replaced. So, locate the filter capacitor and use a multimeter to check the continuity. However, if the filter capacitor fails, the low frequencies won’t be filtered out, resulting in low output. The filter capacitor is responsible for filtering out the low frequencies and makes sure that only higher frequencies reach the converter. In case the load circuit is disconnected, it indicates that there is excessive load on the system and you’ve to reduce the number of electronic devices connected to the battery.

For this reason, you have to disconnect the loads connected to the power circuit and check for faults in the power supply circuit or the load circuit. The first reason behind a low voltage is a short circuit in the power supply. The low voltage output means that the battery won’t be recharged and the electric appliances won’t be powered either. There are four potential reasons associated with the low voltage output. So, inspect the wiring connections and tighten up the loose ones. If the wiring connections are loose, the flow of current will be hindered, resulting in charging issues. That’s because tight and secure wiring connections are important to ensure smooth current and power flow. Secondly, you must check all the wiring connections. While you are checking for the open inline fuse, make sure there are no open wires between the battery and converter as well. So, check the inline fuse and make sure it’s closed. However, in some cases, the inline fuses open up accidentally, which stops the connections between the battery and the converter, resulting in charging issues. The inline fuse is responsible for protecting the circuit of the battery in case of overcharging – it opens up to end the connection. If the power converter is connected to the battery but the battery is not charging, the first step is to check the inline fuse in the battery wire.

So, when you have to install a new fuse, reconnect the battery properly and make sure the new fuse has the same amp rating. The fuse usually blows out when the battery is connected in reverse form, either at the converter or at the battery. If there is no continuity, it means that the fuses are blown and you have to get them replaced. On the other hand, if there are no physical damages, you can use the multimeter to check for continuity. If the fuses are damaged, they should be replaced to ensure there are no hindrances in the current flow. If there is no DC power output, you’ve to inspect the reverse polarity fuses, which are installed on the back of the converter. WFCO 55 AMP Power Converter Troubleshooting So, we are sharing some common problems as well as the troubleshooting guide. However, the power converter also has some errors that you must know about. In addition, it promises noiseless operation and its DC connections are fully insulated.

WFCO is a well-known brand of power converters and the 55 AMP power converter is a three-stage converter that not only manages the charging needs of the RV but also extends the battery’s lifespan by preventing overcharging (overcharging causes damage to the battery).
