When the bake igniter becomes weak or burns out, your oven will not bake. The bake igniter is usually mounted on the oven burner. It's about 1 inch by 4-8 inches (depending on the model), and comes in round or flat styles. If you don't see the igniter glow at all, it's probably burned out. Replace the igniter if found defective. Note: one of the exceptions could be that your oven is set to automatic mode instead of manual. If this is the case, set your oven to manual mode and check again.

If the bake igniter glows red and not bright yellow or white, it is probably because it is too weak. When this happens, the safety valve would not let the gas out into the oven burner. A weak igniter must be replaced.

A faulty igniter is probably the most common cause, however there are others:

-- defective thermostat
-- defective selector switch
-- defective gas safety valve
-- defective gas valve coils

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.

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.

My Electrolux Eog6330xn oven cuts out after about an hour and the ignighter then constantly sparks. the oven then has to be turned off to cool down before it will relight. Any advice.


Hello there Gary and welcome to FIXYA

Usually when an oven won't bake properly or stops baking , it's because the bake igniter is weak or burned out. The igniter is a small, round or rectangular device, that's about 1 inch by 4 to 8 inches. It's near the burner itself. The burner is the tube-type device the gas flows through before it's ignited. It has many small holes on the sides to let the gas, when ignited, form a long, low flame. If the igniter is weak, if it glows red but doesn't get hot enough, or if it's burned out, the gas doesn't flow to the burner and the burner won't ignite. If this is the problem, you may need to replace either the igniter or the gas safety valve. Usually the igniter is to blame. I would disconnect the power to the oven then unplug the wiring assy and remove the part then clean all of the terminals really good then reassemble it then try the oven again if it still does not work properly i would go ahead and replace that part ok
Please keep me posted on how this is going i can give you more help but this is the most common problem ok?
Best regards Mike

MGR5729ADH Ignitor gets hot. Gas won't come on


Hello,

The problem with the oven not lighting believe it or not is going to be that the igniter is weak and not drawing the correct amount of power to allow the gas to flow.I know it would seem since the igniter comes on that it could not be the problem yet since it comes on to me a oven technician with 30 years experience the igniter is exactly what it is.

We have a Maytag gas oven and it takes close to 30 min just to preheat to 350 degrees, however the broil setting works great. Any help would be great...


The problem beleive it or not is that the bake igniter is weak ,and it is not drawing the proper amprage to open the gas valve.If you have a amp meter access the wires to the bake igniter(usually behind the storage drawer) and check for 3.3-3.6 amps when oven is set to bake by clamping the meter around ONE wire wire of igniter make sure only one wire,either one and not both.
if amp draw less than 3.3-3.6 amps replace bake igniter. I know it seems improbable that if the igniter comes on that it could be the problem.Professional appliance technicians who would charge a average of $250.00 to repair your oven,have found when the igniter comes on yet the oven won't heat that a weak igniter is the cause 100% of the time

Glow plug gets red but oven will not ignite. Broiler ignites but has seperate glow plug.


Check to see if you are getting gas to the oven burner. If it will light with a match then look into adjustment of the flow plug, but if it won't light, then look at the gas valve or switch.
