Glow coil comes on but burner doesn't ignite for +/- 2 1/2 minutes then flutters as if valve is opening and closing. the broiler ignites about 40 seconds after glow coil comes one and burns steady. Does the glow coil have a sensor to detect the heat or flame to keep the valve open?

The oven burner igniter
commonly known as the hot surface igniter is used in modern gas oven burners to open the gas valve and to ignite the gas. As the igniter draws electric current it will heat to a high temperature and glow, as well as cause the bi-metal in the oven safety valve to warp and open the valve releasing the gas to be ignited. This sequence normally takes about a minute. Igniters come in both flat and round styles and are very fragile. If the burner does not light then you should check the igniter first. If the igniter does not glow at all, then check for power to the circuit. This is a live voltage check and should be performed by a qualified person. If power is present then the igniter may be open circuit and can be checked for continuity with a multi-meter. If the igniter is glowing, but the burner is not lighting, the igniter may be weak and still be at fault because it requires a certain amount of current draw to open the valve. This check requires the use of an amp meter and should be performed by a qualified person. If the igniter is defective then it must be replaced.
if you hear the valve clicking but no gas the valve is bad.when the burner lights theres a probe that senses that it is lit and sends a microvoltage back to the controller to tell its lit.check to make sure all ground wires are grounded to a clean metal surface.
pull out the racks and remove the bottom floor of the oven,turn it on bake,if the ignitor doesn't glow most likely it's bad,if it does glow and it doesn't ignite within 40 to 60 seconds the ignitor is bad.even though it glows doesn't mean it's good,it works by amps.it takes 3.2 amps.for a flat ignitor to open the gas valve and 2.5 amps for a round ignitor to open the gas valve.
Replaced the igniter. The parts guy told me that the amperage changes with age and use; thus the igniter still glows, but it takes much longer to operate the gas valve with the reduced amperage. Cost - $70.14
I take it the range is electric ignition because you say the top burners have a clicking(igniter) noise. If the top burners are electric ignition then the oven is also. The oven probably uses a hot surface igniter and that is why you do not hear any clicking. Turn the oven on and open the broiler compartment. You should see a bright glow from the hot surface igniter. If you do not see any glow there may be a grounding issue or the igniter could be bad. If you do see a glow but the burner does not come on in a few minutes then give the gas valve a tap with a wrench and see if the burner comes on. Shut it off and then back on several times. If the burner continues to light after this you may have fixed the problem. If it does not come on gas valve could be sticking or igniter is weak.
Typical symptom of a defective ignitor.(even if it "seems" to be functioning, its not sending enough current to open the gas valve) Install a new ignitor that should get you "cookin with gas"
igniter. Does it glow bright orange, then shut off without igniting the
gas? (When the gas ignites there's a large blue flame.) If so, there
may be defective coils on the gas valve. Mounted on the top of modern
gas valves, there are black electrical coils. The coils, when
energized, open the gas valve. If one or more of the coils are
defective, the valve doesn't open and the gas cannot ignite. Because
it's often difficult to properly test the coils, it's usually best to
replace both (all) of them at the same time.
you should have a broil glow coil at tol and one on bottom. to access the bottom, open the door and look to the back on the oven floor. ther should be a srew one on each side remove and lift bottom up. you should be looking at the glow coil. i would also remove the pan drawer for access.it would be abnormal for bth the broil and bake to fail at the same time. if this is the case i would confirm power is leaving control to the selected glow bar. they shoul pull about 3.2 amps. then i would focus on the valve. which is opened by the amp draw of the bar. one wire on the valve is common and the other feeds from the control through the valve to the glow bar
jdelvecchio5Does the igniter (glow bar) come on whenever the bake function is selected.?
If the glow bar does not come on the safety valve will not open - no bake burner. check the electrical harness first then Try changing the igniter (glow bar first) before changing the safety valve/regulator.
