Question about Kitchen Ranges
We have a Viking range hood model number VCWH3048SS. It has two PAR20 light sockets with a dimmer switch which we use halogen bulbs in the hood. We want to start using dimmable PAR20 LED bulbs. Philips lighting says that for their dimm-able PAR20 LED bulbs we need to install a "Leading Edge Dimmer" so that the LED's will not flicker. Anyone know where I could obtain an LED dimmer for this range hood? Viking tells me that that their new range hoods are shipped with the LED dimmer (they still make the same model), but so far I have not been able to get a part number for this dimmer from them.

If you have 120VAC on the center contact of the light socket, and a working fan, but the bulb won't light...the most likely cause would be a disconnected neutral wire (white) in the light wiring inside the hood....assuming everything else is wired correctly.
If you're comfortable with further electrical testing...let me know, and I can describe a detailed procedure to check the status of the neutral wire. Otherwise, you may need the assistance of someone familiar with electrical troubleshooting or appliance repair.

If you're getting 120V at the lampholders, yet it's not lighting lamps that still work perfectly well in other fittings, two possibilitiesspring to mind.
One is that the cap on the bulbs isn't quite compatible with the fitting. Assuming they're some variant of Edison Screw, make sure that the centre terminal in the lampholder is sticking out far enough to touch the terminal on the bulb. Also check whether the lampholder achieves it's outer connection just with a small tab, rather than with the whole of the threaded ring. If so, make sure that this is going to touch the appropriate part of the bulb.
The other possibility is that you've got a high resistance connection somewhere - not enough of an open circuit to drop the 120 V when feeding the Megohm load presented by a meter, but more than enough to kill the supply when you have a lamp load. Only way to chase this is to use the meter on ohms range to bell out all the wiring between the lampholders and bits of the system which do work properly.

The chances are that your range hood light socket was fully impacted with grease from cooking. Shut the power off to the range hood or, in many applications, simply unplug the power cord. Remove the socket. Get a spray can of electrical parts cleaner and saturate the socket through the tiny pin holes you may see at back of socket. shake out all of the cleaner fluid. Somehow hang the socket up with bulb base facing up all night. Hook it up. That might solve the problem.
It worked for me very recently on a 20 year old range hood.
DON'T USE ANYTHING OTHER THAN AN OFFICIAL ELECTRICAL PARTS CLCEANER. Most hardware stores, etc., have it.

the dimmer switch/thermostat is most likely bad. resistor inside is burned.p/n pe050033 you can change it yourself with a little mechanical aptitude.
