Find the house wires to the switch (or switches) and check for voltages being there and then the switches being good.

Sometimes, if the fan isn't used much, the grease / dirt deposits on the motor shaft build up enough to prevent the shaft from turning on start up, it doesn't take much.
try: Remove the filter to expose the fan blades, spin the fan by hand to ensure that the shaft moves freely - if this was the problem the fan should now work, in which case run it on high for a few minutes.
In the fuse box under the hood, driver's side
Is the SLEEP TIMER set (on), or is it getting too hot? I mounted a small fan on the back of my flat screen to blow cool air into the vent holes.
Engine cooling fan RELAYS are located in the under-hood power distribution box. relays #15 and #16. The FUSES that control these fans are also located in the same box: fuse # 2 (30 Amp) and fuse #6 (50 Amp).
Replace the relay/ When the AC Module goes bad , it goes 2 ground & makes the circuit for the fan-causing the fan 2 run ALL the time-REGUARDLESS of the key in the switch or not-& is usally mounted on the evaporator case inside the car on the Passenger side-just under the lower dash panel. Replace the fan control module. Sold a lot of them as a parts salesman at a buick dealership, relays and the fan module ar located on the passenger side of the blower motor under the hood, been there done that!
It is right under the hood. One should contact with the dealer if its giving issues. You can unplug the fans at the radiator and hook them up directly to 12 volts from the battery to check if they work alright.
The fire thing
go through the vent
what is the distance required between the stove top and the microwave/fan vent
Please note that if you have to ask a question like this then you probably aren't qualified to do electrical work and for your personal safety I suggest that you find someone that is to do the work. That being said a qualified electrician would land or splice your wire on the line side of the existing fan switch. The existing fan switch won't control the new fan but the new fan will be on the same circuit. This is called wiring in parallel.
You should be using solid ducting for a range hood vent
The Broan Allure III QS336 36" Under Cabinet Range Hood is a canopy hood that goes above the stove. This type of hood has a ducted exhaust that will help ventilate the area.
To fit a kitchen hood extractor fan, first you must decide where you want the duct to be. You need to attach the vent cap, then fasten it with the supplied fastener. Put the vent hose into the hole to cut in the wall until it hits the wall and secure the framing to the wall.
One would use a hood filter over a stove (also called a range) that has an exhaust fan mounted in a hood over the stove. The filter is used to trap large particles and pollutants and prevent them from recirculating, improving the air quality in the kitchen and surrounding areas.
You must either have an exhaust fan or a window in the bathroom, and a range exhaust hood over the stove, or an exhaust fan that drives away any smoke, in the kitchen.
One cooling fan, one intake vent and one exhaust vent.....
it is a vaccum hose that has a tear, replace hose that is most of the time by your a/c tank under the hood.
You are remodeling the kitchen and decided to go with a professional sized gas stove top built into the island. You never had that type of setup before. You always had a free standing stove with a range hood above it. How do you attach range hoods where you have no cabinets to fasten them to? There is an easy solution, a downdraft range hood.The range hood for that type of scenario is built into the lower cabinet, directly in back of the stove stop. Only a small portion of the range hood shows when not in use. When you cook, just push a button and the range hood will rise and do what range hoods are supposed to do. Problem solved.If you have a regular set-up with a free standing stove and a short cabinet above, then you have the perfect arrangement for a normal range hood. The hood would be attached to the bottom of the small upper cabinet and should be vented to the outside. When turned on, that vent should send the cooking smells to the outside. If your range hood is not vented, then it is not doing the job.This type of range hood comes in white, black, or stainless and you may find an almond color in some stores. They usually have a light kit built in and the venting fan normally has at lest two speeds. These types of range hoods are rather inexpensive. It is something you need to finish off the space, if you do not want a microwave oven with a vent. Perhaps you just bought a counter-top microwave, which you are happy with. Then all you need is the inexpensive range hood and have it vented properly.If you want the built in microwave with a built in vent, go for it. This is the look that most people currently go with. It frees up counter-top space and it has a vent and a light built in.Depending on where your stove or cook top is located in your kitchen will pay a role in determining which type of range hoods is the best for you
