see post #75 above... added a large capacitor across the power leads. Squeaking gone.

Not sure what's going on... mine is silent on exhaust (a bit of a cyclical clack on intake)... it might be the unit as they are not well made and may have interference of some kind. A couple folks have said that they bought two after the first failed. Might just be a crap shoot as to the quality. Mine has held out for a total of daily use for 3 months over two years (touch wood). Could the noise be coming from the motor bearing? With uneven weighted fan blades putting a piece of duct tape on a blade to balance can help if that is the source.

oh man, I just looked in my spare parts bin and put in the biggest one I could fit. Electrolytic type for sure. I could get pics?

OK, so here is a trial fit of the PWM speed controller:
And this is the capacitor, 25V 4700 microfarad polarized version. No fancy testing here to see what was best. I just had this lying around and used it.

Quick heads up/caution ...
With my front vent I had to order a fan & other material to install. Decided I liked having a rear fan. Not much draw. The front vent was more problematic than the rear vent. The rear was just about altering the already installed FWC 3spd fan. The front went pretty smoothly with the actual controller unit much like the rear install. Here is where I had an issue ...
Turned the fan on & it instantly blew the fuse. New fuse, blew it, third fuse blew it. I figured it was the controller. Ordered another controller & finally got around to install months later. Same issue, instantly blew the fuse. My son suggested the incoming FWC wiring could be the issue. Well, Yes, the White & Black were Reversed. Not sure if this is typical. Luckily the fuse took the hit like it should. I have not read this entire thread to see if this occurred elsewhere. Encountering reversed polarity is not expected.

Black/White reversed? Yup. Been there, seen that. In my world, black is ground. NOT in the RV world.
