Why is My RV Plug Melting?

Why is My RV Plug Melting?

If your RV plug is melting, do not touch the hot structure and immediately cut off the electric power supply to repair the equipment. The damages of the particular device affect the overall efficiency and performance.

Why is My RV Plug Melting? In general, RV plug melts due to improper plug coating, frequent short circuits, and corrosive conditions. Also, the clogged plugs, old age devices, and insufficient plug cords cause melting. In addition, broken plug parts and faulty battery terminals warm and melts the plug. 

These are inexpensive products but offer crucial tasks in an RV. Always select similar things for replacement.

Why is My RV Plug Melting?

RV Plug is melting due to fluctuation of voltage and improper heat ranges. I have added 12 main reasons that cause the melting of the plugs along with proven and easy methods to fix this issue.

Excessive current heat production

The RV plugs comprise low voltage conditions, and they work effectively due to moderate electric flow. However, in few cases, the demand for electric current enhances more than the standard limit.

It produces an excessive level of heat which is not suitable for an RV plug. In addition, a high level of currents flows through the plug, and it demolishes with time. 

The excessive level of heat melts the plug, and it breaks. As a result, it stops working, and it fails to offer moderate levels of voltage.

Instant repair of the plug is necessary for such conditions. Avoid RV attachment with a high voltage electric station.

Take the help of an expert to resolve such problems.

The poor quality plastic coating on plugs

The plugs have a plastic coating for resistance to heat and electric current. It remains stable with high-quality material. 

The plastic coating is a cover for the protection of these small structures. However, the fluctuation of current can demolish the layer of external plastic covering. 

It cannot tolerate such a high level of electric flow. Eventually, the outer material melts due to such conditions.

The repairing and damage removal is necessary. It is essential for the standard performance of the device.

Consult an expert to purchase these materials. Then, consider the budget and select them accordingly. 

The expensive products are sufficient to resist such electric modifications. As a result, the plastic coat remains intact in one particular position.

Frequent short circuit connection

The electric wires of the plugs join with the RV battery for the flow of electricity. 

The poor connection of electric wires with the connecting joints because of sparking.

The fluctuation of current happens, and it travels towards the plug. Therefore, the temperature condition of the device varies due to irregular current flow.

The voltage changes are not suitable for these structures. Therefore, they cannot remain intact in one form and starts melting.

As a result, you can lose the complete device, and the connection cuts from the central electric panel.

Approach the RV battery, and observe the electric wire connectors. Use a wrench for the tightening of the connector and electric wire.

It provides a regular electric flow, and voltage remains at a particular level. Replace the melted plug for the accurate performance of the RV electric system.  


In few conditions rusting of the plug happens, and it leads to these conditions. The old age of plug leads to corrosive properties and results in damages. 

The traveling conditions of RV to those areas which have high humidity levels can generate moisture. The humidity causes the accumulation of corrosion, and it can melt an RV plug. It does not work efficiently after these issues.

Replace it with a new device and take technician help for error-free procedures. Avoid the penetration of moisture inside these electric panels. 

Cover it with a fabric cover or any other polythene bag. 

Dirty plugs

Open plugs have more chances of dirt accumulation. In addition, open its doors and windows lead to the penetration of dust particles. 

They accumulate inside the plug, and it ceases the standard performance. As a result, the attachment of the plug and outlet declines. 

It happens due to clogging of plug and outlet. As a result, the system loses its compatibility and requires instant repairing.

Cleaning its parts and maintenance is necessary to avoid such conditions. 

Remove the dirt clogging from internal structures. 

Avoid the penetration of dust particles inside this structure. 

Broken plug connectors

In few circumstances, the RV user removes and adjusts the plug inside an appropriate position. However, these conditions involve a lot of strength and excessive force. 

The person pushes it despite such damages. They appear without any notification. 

It gets excessive heat due to high and low voltage conditions. 

Approach its broken connectors and repair them. Then, discard the melted structure and alter it with a tool. 

Old and used RV plugs

The plugs are essential structures of an RV for the supply of electric current at various levels. Therefore, they remain installed in an RV for long periods. 

Few of them break due to old age, and vulnerability towards damages enhances. The broken parts cannot tolerate the current changes.

It produces high levels of heat due to constant high voltage and irregularity of current. As a result, its parts get hot, and its sides start melting.  

Maintain a record of their installation. It helps you to replace these structures after a specific time limit.

Hire a technician for the removal and replacement of a new tool. 

Insufficient Plug wire

An electric cord connects the plug with the RV battery. It is a connecting source with the electric current of the system. 

In few cases, the electric cord damages, and people replace them with new connections. The problem generates due to human negligence, and a person can buy an insufficient length of wire.

It cannot develop a proper connection between the plug and the battery. As a result, it results in voltage and temperature levels getting higher than the standard range. 

Always consider the size of the old connecting electrical cord before buying a new structure. 

Faulty electric wiring

The electric wiring of plugs connects with the RV battery.

In few situations, the battery terminals break due to old age and voltage modifications. 

All of it results in high heat conditions. In addition, the resistance leads to peak current levels, and it offers high electric flow to the plug cord. 

It starts melting and wears from various points. The insulation of the cord declines, and it cannot handle the excessive voltage limits. 

It passes to the plug, and it starts getting hot. The melting of plug sides occurs, and black spots appear on the surface. The device stops functioning appropriately due to these damages.

Identify the broken parts and repair the damages if it is possible. 

Replace the broken connectors of the battery and install them properly. Then, replace the plug and align its performance with the cord and battery. 

Broken/open parts

The electric components comprise various parts like manufacturing material and other things for eclectic connections.

The excessive voltage flow and other vulnerabilities lead to the breakage of the structure. The broken parts of this device are not suitable because they have lesser acceptance for electricity. 

Heat development is natural during such events. As a result, the melting of the component occurs, resulting in the inaccurate performance of the overall system. 

Take expert help to resolve such issues and take preventive measures before burning the electric panel. 

Inaccurate plug fixing

The inaccurate fixing of an RV plug means an improper installation of this structure. In addition, it results in an impropriate connection of the system with the electric source. 

The misbalance voltage conditions can make the device vulnerable. 

The device cannot work appropriately after such conditions. Access the plug and observe its fixing ability. 

Push t back inside in case of minor damages. If the tool melts completely, then changing the instrument is the only option. 

Sparking of plugs

The loosening and improper limits of heat inside these small structures burn them from inside. It gets warm with time and starts melting.

Turn off the electric connection of your RV in these situations. Allow the cooling of melted RV plug. Then, discard it from the system and replace it with another tool.
