Brake motor buzz??

[rnreinertson]

I have a 2017 Designer and I noticed a buzz coming from the brake motor that sits in the front of the RV above the generator. Any ideas what it is? Where is the breaker or fuse for it? Any ideas or help would be appreciated.

The buzz is coming from what I believe is the Dexter Electric Over Hydraulic Actuator that Runs When Disconnected from my truck.

Are you sure the noise is coming from the hyd. brake pump/actuator? I don't believe it should be running if the brakes aren't activated. Mine doesn't come on unless the brake pedal is pushed or the breakaway switch is pulled. Sounds like something is wrong somewhere. The noise isn't coming from the transfer switch is it?

Thanks for the reply. Your reply is exactly what I initially thought as well. I did trace the noise directly to the motor though. The only other possibility is that if the real issue is somehow inducing a slight vibration to the motor making it appear to be the problem. I will continue to dig into it. Thanks again for the reply.

An easy way to check if the motor is buzzing is remove the power to it.
