20 Most Recent Panasonic WhisperCeiling Bathroom Fan FV-11VQ3 Questions & Answers

The roaring noise is probably the fan blades (looks like a hamster wheel) are worn out as it rotates on the spindle/shaft.

It may be a problem with the 4" exhaust ducting, that connects to the exit part of the fan, has come loose. Theres a damper (kinda like a flapper) at the fan/ducting joint may have broken off and may be sitting sideways in the ducting flapping around inside the duct.

At any rate I highly doubt its wiring. Sounds like its time to pull the fan cover off (turn the power off first via the wall switch or the service panel breaker would be even better) and look at the fan blades. Clean off any dust bunnies, lint, etc. and turn the fan back on. Did the noise stop?

If nothing looks out of place and it still makes noise you'll have to get in the attic and remove the ducting from the fan and see if theres a problem at the connection there. Maybe a squirrel put its bedding in the ducting? It happens.

Could be lots of reasons for the noise but wiring it wrong wouldn't cause roaring. The fan wouldn't work, or worst burn up, if wiring was the issue. The problem is the more than likely the fan blade assy is worn out or something is restricting the air flow in the ducting going to the outside of the house.

Yes and maybe.
If you open unit, usually fan motor is plugged in, and motor is removable with bolts.
The problem is finding new fan that fits same housing without spot-welding and drilling.
I did google image search for "replacement vent fan motors" and results show choices.
For example Nutone:
If you can locate same brand vent at local box store, you can use parts from new one to repair old one without project of replacing fan housing.

20 years ago, motors went to electric repair shop and they rewound the motor.
But today, motors are landfilled or shipped overseas for recycling.
All costs are energy, and right now, cost of re-wind is more than buying new motor, or new vent.

The green wire is the ground, just like the bare wire. Attach black to black, white to white, and green to bare.

Short answer: yes but if you wire them in series when the one closest to the power source burns out the others will not work. Electricians wire all light fixtures in parallel. I think you really want to know if you can wire 3 led lights on the same circuit without any issues. Two things to look at 1. box the gimbals came in will tell you how they are rated for installation. Some can be put against insulation, some cant. 2. As far a power is concerned...I am assuming this is a residential install so you need to check what if anything is on the circuit with the LEDs. Hooked up by themselves will not cause any power issues. But adding them to an existing circuit may. If they are going to be added to an existing circuit you need to find out what else is on the circuit so that adding the LEDs will not overload the circuit.
