Going nuts with Converters

Alright, so I'm trying to make sure my converter is operating properly. It seems people all over the web have different ideas as to whether humming is normal, not good, or danger Will Robinson! My converter is a WFCO 65amp Power Converter. It appears to hum all the time, regardless of electrical use or battery charge. It is not the fan that I am hearing - as the fan exhaust is not blowing air. I'm not sure if the fan has ever turned on. The converter is warm, but not hot (I suspect this is normal). Also, how do I know if I have one of these solid state converters? I assume this is not one due to it's somewhat noisy humming noise. So, of course, is this normal? How much humming is normal? How do you know when it's going bad?

As to voltage output to tell if it's charging - your voltmeter (either the coaches or a multi meter) will indicate battery voltage when the converter is off, and will raise a volt or so when the converter is turned on. The difference will be noticeable.

As for noise level. I could not hear any noise, other than a very slight sound of the fan, on my previous or current coach. Others with wider or differing experinces may chime in here.

If you put enough load on the converter, it will get hot and the fan will come on. What you might be hearing is the fan trying turn on and the fan is bad. If the fan is bad, it will eventually fail at the worst time.

Well spec what you are hearing is the normal function of the Transformer, some transformers hum some don't. Usually due to the construction of the transformer itself, or the box it is mounted in.
If the converter is warm, not hot, all should be normal, if you can place your hand on it and keep it there for a while, all is well.
Have you ever heard the transformers mounted on telephone poles humming, normal when the transformer is under load.
Here's everything you always wanted to know about transformers.
Hope this helps
