New Regulator Hum

[gunafulltime]

We just replaced our auto-changeover propane regulator. This new one makes a humming sound when an appliance in the coach is pulling gas for normal operation. The sound is audible from 10-15 yards away. The tanks are full. The hoses are new, and all of the connections are tight. I appreciate any help!

Just a shot in the dark here, but if the old one didn't hum and the new one does I would say there is a problem with the new one. They should not hum at least at a level you could hear.

I've seen that happen twice. Once on a friends TT, it was one of the pigtails, and once on our own, It turned out to be a combination of cold temperatures, and the tank being about 2/3rds empty. Also brand new pigtails were on ours at the time, but hasn't 'buzzed' since I had the tank filled.
