Question about Viking VWH3048 Kitchen Hood
The blower will spin once started by hand, and then properly controlled by the rotary speed controller thereafter. The fan blower just does not begin turning/spinning on its own.

If I'm not mistaken, these are the same as the Dacor range vents. If thats the case, we have seen a LOT of bad control boards on these, but I can't say I've ever had one with quite the symptoms you are describing. You may just need to reset the filter timer, as that light comes on every 40 hours of use I belive. But I think you said you have already done that. If you have cleared the light per the instructions and it just keeps coming back on, then you probably do have a bad control board. That should be located on the lower right of the unit behind a small square acces hole, if its like the model I am familiar with. They arent too hard to change, just make a diagram of all the wires before you pull em off and make sure to turn of the power first. One more thing, if the filter light doesnt come on after you reset it, try taking the blower motor box of the front of the unit and checking the 3 prong connector between the fan and the vent and make sure it hasn't come undone or that one of the terminals hasnt backed out of the connector, causing a poor contact. Good Luck!

Turning any knob starts the spark via a switch behind each which should disengage when the (any) knob is turn further.
One of your switches is stuck.
I think you should be able to remove the range-top for access and find the offending switch.
It is probably gummy from a spill and is no longer in solid contact with the cam that operates it.
A solvent/lubricant such as WD-40 sprayed on the plunger of the switch once you can see it and operating the knob back and forth should free it up.
It might be wise to turn off the gas supply while tinkering with the range - blow your house away and the range won't matter. :-(

think i would call viking back and ask for refund of inspection fee and go by the bad switch scenerio the electrician said new fan that would be considered flaws in workmanship in most states dont know where you are located but pretty much same anywhere most inspectors for these companies always try to blame problems off on installers hold your ground and make them fix it and refund that" inspection " fee I've been doing electrical work for several (20+) years it takes longer than 5 minutes to troubleshoot something like that good luck

I did some more troubleshooting and figured out how to get the plate off that houses the switches. I disconnected the fan switch and created a safe electrical by-pass. I re-connected the main power supply and sure enough, the fan worked. Issue = defective switch. Currently looking to order replacement. Problem solved.

FLASH covers a multitude of possibilities. What is the voltage of the blower motor. What you are describing often happens when 220 is wired to a 110 lighting circuit. I would not be running the blower motor although I hope it has inherent built in motor protection. If the voltage is applied higher to light bulbs they become flash bulbs. Florescents can become fire fixtures fast. If you are not an electrician back away from this and disconnect power at your breakers. Do not open up and trouble shoot if you are not qualified so you do not get embarrassed and have a dirt nap. It only takes about 40 vo;ts and a few milliamps cross chess to kill you. Also when ever you turn something on start and keep the habit of using one hand to turn it on and one hand to grab your pants behind you. OK OK or skirt. This prevents a cross chest shock . Old Navy (USN) death defeating rule that sved me many times and still. Remember call a pro when you do not know .
