When the igniter glows but the gas does not come on it is usually the igniter not reaching the correct amp draw.
When the igniter does not reach the correct amp draw it may allow the gas valve to partially open or not open at all. The igniters are inexpensive and easy to replace. This video will walk you thru the correct procedure for testing an oven igniter. It may be a different model but the testing will be the same.You can also enter your model # for diagrams and illustrations of your specific model. Not all models are available. All parts come with installation instructions.
Now if the oven is staying on all the time, this usually indicates the relay on the main control is stuck/melted in a closed position. This will mean you will need to replace the control again.

Nothing Works, or the Oven / Range / Stovetop Works Only At Certain Times:

1.Home breaker flipped or the fuse blown?Possibly an electrical surge has flipped the breaker. Check your breaker or fuse box and replace or reset as necessary.
2.Power cord plugged in?Grab the plug and wiggle to determine a good connection.
3.Power cord damage?Damaged rubber with wires showing through or the wire is being pinched can cause issues. Electrical tape is acceptable for covering damaged wires.
4.Aclicking sound could be something wrong with a relay. Check for any loose connections around the main control board on your oven. The click you hear is a relay losing power and switching back on. If the clock resets then something is causing power interruptions to the board.

If your oven has internal fuses, a wiring or component problem could have caused a fuse to blow. A blown fuse is an indication that a component has shorted or failed, and the problem will need to be corrected. Most ovens that use fuses will have an indication of the circuits that are affected by a particular fuse. If an oven fuse has blown, then you should inspect the oven element and the associated wiring to determine the cause before replacing the fuse.

THINGS TO CHECK:


The oven safety valve
(also called the gas valve) is the part that ensures that gas is not released until the igniter has reached the correct temperature needed to ignite the gas. While this part can fail, it is uncommon. If the hot surface igniter does not glow you should first verify that you have voltage to the circuit. This is a live voltage check and should be performed by a qualified person. If voltage is lost at the valve terminals then you should verify the continuity of the bi-metal in the valve using a multi-meter.

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.

Magic Chef cgr3765adc, oven will not turn off. If the unit is plugged in the oven ignites and would continue heating unless disconnected from electricity.


follow this test and fix it. God bless you

Bake Element

If the oven won't turn on, check the bake element. The bake element is a black tube near the bottom of the oven about as thick as a pencil. When it is operating normally, the bake element will glow red hot. If the oven won't turn on the bake element may have burned out. It is often obvious to see where the bake element has shorted out because there will be a hole or break in the element. If the bake element has burnt out or shorted it should be replaced.





Oven Igniter

Even though the oven igniter may be glowing, it may be too weak to allow the gas valve to open. If the oven won't turn on and the oven igniter glows for more than 90 seconds without igniting the gas flame, the oven igniter should be replaced. This is the most common part that fails when the oven won't turn on.




Broil Element

If the oven won't turn on, check the broil element. The broil element is a black tube near the top of the oven about as thick as a pencil. When it is operating normally, the broil element will glow red hot. If the oven won't turn on the broil element may have burned out and caused something else to short out. It is often obvious to see where the broil element has burned out because there will be a hole in the element or blisters on the outside of the element. Test the broil element using an Ohm meter. If it has continuity it's OK. If not, it should be replaced.





Incoming Power Problem

Although not as common, if the oven won't turn on it is possible that the appliance is not receiving proper voltage. Electric ovens require 220 volts of alternating current. If for some reason the appliance is receiving significantly less, the oven won't turn on. Check for proper voltage using a volt meter at the socket where the appliance plugs in.


Oven Control Board

The oven control board has a set of relays that turn on and off power to the bake and broil circuits according to the customer settings and sensor input. If the oven won't turn on the problem is usually with the heating components. However, if the oven control board is bad, it might not send voltage to the heating components. To determine why the oven won't turn on, first test the simpler components in the circuit. The oven control board usually can't be tested and will have to be replaced if it is defective.





Thermal Fuse

Although not as common, if the oven won't turn on the thermal fuse may have blown. The thermal fuse is designed to protect the appliance and help to prevent a fire. If the oven gets too hot, this fuse trips. The thermal fuse is not resettable and will have to be replaced. It can be checked for continuity. If it has continuity, it's OK. Not all ovens have a thermal fuse.






Relay Board

If the oven won't turn on and the appliance is equipped with an oven relay board, one of the relays on the board may have failed. Normally the oven relays are located on the main clock control board and not on a separate oven relay board. If the oven won't turn on it is more likely that the cause is one of the more common problems listed for the model. If the other, more common problems have been checked and Your oven has a relay board, it may need to be replaced. Oven relay boards are not repairable.





Oven Thermostat

If the oven won't turn on, the oven thermostat might be defective. Although this is not as common as other components, the oven thermostat sometimes fails completely and does not allow current to pass through. After checking other, more common components, consider replacing the oven thermostat.





Heat Selector Switch

If the oven won't turn on, be sure the heat selector switch is set to the right position. The heat selector switch completes the circuit to either send voltage to the bake or broil circuit. If the oven won't turn on, the heat selector switch might also be defective, although this is not very common. The heat selector switch is not repairable, if it is defective it will need to be replaced.





Oven Safety Valve

The oven safety valve works with the oven igniter to provide gas to the burner. If the oven won't turn on it is possible that the oven safety valve is defective. However, this is very rare. Most often, the oven igniter is too weak to allow the oven safety valve to open. If the oven won't turn on, check the igniter first.





Oven Valve and Pressure Regulator

If the gas oven won't turn on the oven valve and pressure regulator might be at fault. This is not common. Very often people misdiagnose a defective oven valve and pressure regulator when the oven won't turn on However, this is almost never the cause. Look at other, more common components before replacing these.

Mod# xfg374lvq stove: Both the oven and the broiler will ignite, but only stay on for a few seconds. It does not try to reignite. Is this the control module?


Most modern ovens use an electronic control board
to control the oven functions. These models will use the control board to operate the oven safety valve on a gas range or oven, and the bake and broil elements on an electric range or oven. If there is no power to the igniter circuit, or the element circuits, then you should check the control board to verify that there is power at the appropriate output relay. These are live voltage checks and should be performed by qualified persons only. If there is no output voltage then the control should be replaced.

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.

The oven sensor: works with the oven control board to regulate the oven temperature. If there is an oven temperature problem, this sensor might be defective. The sensor can be tested by using an ohm meter. As temperature rises, the resistance measurement also rises. The manufacturer of the oven sensor determines the correct resistance, Oven temperature problems can be caused by other things, but this is one of the common causes.
Beware on some models now most of these ovens they are electronic and they are integrated into the control itself
some different sensor ohm readings at room temp. approx 16 ohms at room temperature and at 350?F it is 29~33 ohms.

The oven safety valve
(also called the gas valve) is the part that ensures that gas is not released until the igniter has reached the correct temperature needed to ignite the gas. While this part can fail, it is uncommon. If the hot surface igniter does not glow you should first verify that you have voltage to the circuit. This is a live voltage check and should be performed by a qualified person. If voltage is lost at the valve terminals then you should verify the continuity of the bi-metal in the valve using a multi-meter.

I have a Kenmore Gas Wall Oven Model Number 911.30469894. When BAKE is selected, temperature shows 100 degrees and the oven never starts up or gets hot. BROIL works fine. Thank you, John


The oven control supplies voltage to the oven igniter/gas valve circuit. When the oven control is set to Bake, voltage is supplied to the oven igniter which should glow bright red to almost white hot. Once the igniter comes on and begins to glow it must pull enough current to cause the gas valve to open so the burner can ignite from the igniter. I added an image below with the theory of operation. Click this link:--http://media.fotki.com/1_p,swbbsqrsgstsqkkxgtqsskgwtqkq,vi/wrgtsbrktxwdfwfbgdg/1/1303472/5961857/image5576034710104836299img-or.png

----Open the broiler drawer and then set the oven control to bake and watch to see if the glow bar igniter glows or not. If it does not glow, the failure could be a broken Igniter, failed oven control board or gas valve. If the igniter is glowing red, then it can be possible that gas valve is faulty. To see how igniter looks. See the fig below:--

To order this part click the link below:--

http://www.repairclinic.com/PartDetail/Hot-Surface-Glow-Bar-Igniter/1990?modelNumber=911.30469894

------------

Also to confirm, check to see if the igniter is getting 120 volts when it's turned on. If it gets 120 volts, then your safety gas valve is bad because it's not letting the neutral go through. Otherwise, if it's NOT getting 120 volts, your control board shorted out and you need a new control board.
But as you mentioned that control board is replaced. So igniter should get 120 volts. If valve is faulty. But if igniter is not glowing then its faulty igniter confirmed.

In most of the cases the igniter is faulty, because gas valve getting faulty is very rare. But still getting the voltages checked, will confirm. These will help. Thanks. Helpmech.

My Jenn-air oven won't turn on. It's model number


My Jenn Air 1995 wall oven was working fine until one day the oven and the oven gas burner did not turn ON. I had electricty (make sure you did not trip a breaker) since my front panel LCD and clock was OK. I had a good gas supply.

My oven is an "pilot-less" oven, it uses an electric igniter. Although the "ignitor" was "glowing red hot", the problem is that the gas valve depend on a certain amount of current. If you have a 120V house system, I think the valve needs 3.3 to 3.6 amps to turn on. The current flows through the igniter and then through the valve, as in a same path, like water. So you need an AMP meter to check proper current flow. I read 2.4 amps. I replaced the "glowing red hot" igniter with a new one, Vo"la it was fixed.

Bottom line if you have the oven plugged in OK and you see some life (clock), and you have the gas turned on, most likely the igniter is bad. Second choice would be the oven's thermostat (the temp knob that you turn, say to 350F), or it could be the gas valve.

All three are in same current circuit. The igniter gets the most abuse so I would start there first -good luck!

Oven does not light


even if the ingitor glows, and the oven wont lite, the odds are that the ingitor is bad. it must draw 3.2 amps to open the gas valve. the only way to test the ignitor is with an amp probe. replacing the ingnitor is about 90% a sure thing.
