Just stopped working. No noise, nothing. Just up in attic one day and noticed fan not moving. We have checked connections. It does have electric power getting to it. It is about 4-5 years old. What could the problem be? How long should your fan last?

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.
remove the cover and clean anything in the vent , check the fan for anything that could be touching it, as the back draft comes through the vent, something could just be touching the fan blade as this draft makes the blade turn slowly, which would create a ticking noise
I would check the bearing on the fan motor .You can try to move blower back and forth and if it moves more than about 1/8 inch then you may need to replace the motor. Check the mounting bolts that hold squirrel cage in placeAlso check the bolt or set screw that holds blower to motor shaft to make sure it is not letting the blower move when the motor is running. I would clean the fan and motor as well as you can and oil motor if it has oil ports. Hope this helps you. Thanks
If teh fan had burnt out then there is every possibility that your contactor, the timer, the compressor must be checked. Replace the fan as you had confirmed and put the set on. If the compressor works and the cooling comes on fine then there is nothing to worry. But if you notice any smell or a different noise then shut off and open the back side to check from the contactor onwards to the compressor. However if the compressor works well then you are lucky . hope you get along to do this. Good day
check the unit in attic for iced up and outdoor unit you may notice ice on lines or connecting tubing and in attic also-------- if so turn unit off at thermostat and leave fan switch on the thermostat to on while sytem switch is off
should be nothing running but the indoor fan
will have to thaw if it is iced up for a while couple hrs. a guess
you will know when it is thawed as your airflow will begin to come back
check your air filter to be sure it is clean
suggestion only-- keep your house thermostat set at 70 degrees or above
you may have developed a refrigerant leak (freon) which would require a hvac service tech to verify.
if it was iced you can turn all back on and try again once you have good airflow again.
or if your system has not been serviced lately? might be a good time to have it serviced?
Yes, the mouse was probably attracted to the warmth and food odors in the duct work and may have gotten trapped in the vanes of the fan and died. I'd act fast...
The best bet is to remove the oven from the wall, or almost from the wall, so you can see the area of the hood vent exhaust fan.
This is safer with two people and the installation instructions will be of great help.

Have you noticed more frost in the freezer than usual? It sounds like you may have moisture building up and freezing around evaporator fan. The fan blade hitting ice will cause the buzzing until it stops it completely or the evaporator clogs with frost and blocks airflow. If you have frost on food in freezer, check the door seals and make sure nothing is keeping doors from closing completely if you release them about 6" from cabinet.
