Re: ovens wont light , glow bars work both ovens wont...
The problem is the ignitor or both of the ignitors are not working properly remember just because they glow doesn't mean they are good they have to draw at least 3 amps to open the gas valve if not they will glow all day let me know how you make out

If the glow bar is glowing and the oven doesn't come on in about 30 - 45 seconds.... it probably is the glow bar that needs to be replaced. BUT it could be the oven valve. Usually it is the glow bar.
The glow bar is wired in series with the oven valve and even if it is glowing it may not be sending the correct voltage through to the oven valve.
To change the glowbar... unplug the appliance, unscrew 2 screws holding the metal bracket to the burner and remove the ignitor. You can cut the 2 white wires going to the ignitor and use ceramic wire nuts with the new ignitor.
Unplug the range. Remove the oven racks. remove the oven base pan. remove the flame spreader pan. remove the glow bar ignitor on the left hand side of the gas burner and replace it with a good ignitor.
ok try your broiler if it lights change the glow bar in the lower oven the glow bar acts as a safty if it doesnt reach a certain temp the safty valve wont alow gas to enter the broiler and bake are on seperate ignighters if neither work change the safty valve
ok try this turn the bottom oven on count to thirty then smack the safty valve with the plastic end of a screwdriver its the square box with two wires on it that the burner tube goes to underneath if it lights replace it
I suspect you may have a bad igniter. They will still glow nice and hot, but if they are weak the gas valve will not open. This is actually a safety feature. Depending on which type you have, the glow bar igniter is supposed to draw a certain current potential before the gas valve will open. Here's the current readings for both types:
Round Glow Bar: 2.7 to 3.2 amps
Square Glow Bar: 3.2 to 3.7 amps
I would try to to determine if the igniter is good or bad before proceeding with a gas valve replacement. Generally, the igniter is a common fail item. Let me know if this helps.
Remove the bottom of the oven you will see 2 screws in the back. once you do that there is a flame baffel on top of the burner held on my one screw. remove that. now turn the oven on and watch to see if the glow bar comes on. I would say it wont or if it dose it is to weak to open the gas valve. Replace the glow bar and you will be back in business. the glow bar is a ware item everytime theoven is on and is heating the glow bar is on . good luck
