Whirlpool MOD GS 445LEMS 4 oven and broiler will not light , the burners work OK

sounds like control board defective, technician will have to verify.

if they work and light your stove then leave them alone,

They may have accidentally turned off a little gas cock which is cunningly hidden on the front panel can\'t remember if it\'s top or bottom, it isolates the gas to the main control valve.

Sounds like the heating/starter element went out. This item is very delicate and will break if touched. They are used on almost all newer gas appliances. It takes about 3 minutes to check. Turn the oven on and look down near the burners with all of the lights in the room out. You should see a glow for a while, then it will click off for a while and then come back on. If not, then turn off the oven and get a flashlight and look for the starter element to see if it is broken. It is about one inch wide, two inches long, and 1/4 inch thick. If you do get a glow then this is good news, the element is not broken. However, the element operates a thermostatic switch which operates the gas valve. This switch may be broken. The switch and the starter element usually come out together when removed.

If you have a pilot light, it's in the oven section you take the bottom plate off with the 2 screws holding it on. It's going to be in the back by the burner valves. Most whirlpools don't carry pilot lights.

Unplug it for a while then plug it back in it might reset it's self.

either the gas valve for that particular burner isnt opening,or if all burners are like this then the dual valve that feeds the broiler and stovetop has a bad stove top side of valve portion its underneath the oven cavity behind the lower pan drawer

I have a GE Model Cooktop JPG337BEJ3BB and the burners are flaming to high. How do I turn them down?

check and make sure the bake element has continuity.If there is not continuity with your ohm meter then replace the bake element.
If it tests good the replace the main Electronic control board or the oven switch which ever the unit is equipped with

Andy, sounds like you lost a leg of power. Check the breaker box first. Maybe the contractors tapped an existing breaker instead of adding one for the burner/broiler. You would have to check the terminal block on the range. Should read 120V from each end to center and 220V across the two outer terminals. If you don't have this, something got messed up with the contractors. Catriver..post back
