My RV's Power Converter is Humming Very Loudly
Why is my RV’s Power Converter Humming
2004 Montana 5th wheel. I am full time. My converter box is making a loud humming noise. Very loud. Just started 5 days ago. Is there a fire danger here?
ANSWER: Hi Shirley to answer your most important question, yes, under certain circumstances a malfunctioning RV Power Converter can cause a fire in an RV.
The Converter is an important part of your RV's electrical system. All of the lights in your RV run on 12 Volt DC power and so do other important items such as the RV's Furnace, exhaust fans, etc. When you are boondocking or going down the road your RV's house batteries provide the 12 volt DC power for these items.
When you plug in your RV to 120 volts the converter takes over the job of supplying 12 volts to all of these items. The converter in most cases also provides a charge to your RV's house batteries.
Some buzzing or noise from a Power Converter
is normal and in some cases you may even hear the converter's cooling fan kicking on and off. The fact that the sound that your RV's converter is making has increased significantly is a sign that there could be internal problems with the converter.
In most cases when a converter starts going out it will either fail all at once and in some cases make a loud popping noise or produce a puff of smoke. In other cases it will not produce proper voltages etc. In either case you need to have a certified RV Technician take a look at it to see if it needs to be replaced.Just a warning here:
Power Converters are not user repairable so do not attempt to open it up and see if you can fix it as you could really create a situation which could cause a fire in your RV.
