    I replaced the ignitor and the safety valve. The oven will operate properly in self clean and broil mode, but will not work in the bake mode. the ignitor will not operate, but the burner will flow gas.

Why my oven does not ignite, or gas turned on?


GLO-SIL IGNITOR MAY LOOK LIKE IT'S WORKING BUT IT'S PROBABLY NOT GETTING HOT ENOUGH TO ALLOW RESISTANCE TO FLOW BACK TO BURNER VALVE AND WARP SWITCH TO ALLOW GAS TO FLOW TO BURNER. REPLACE IGNITIOR

Tip

Replaced the oven ignitor with not luck, broiler used to light and gas flow but...


If your gas oven is not working or not heating then you need to check this out. Today’s gas ovens are not often do not use the simple thermocouple with a pilot to prove the flame anymore. They have a much more complicated method of lighting the burner and proving the flame.

The use of electric igniters has become the standard for many ovens today. The thermostat calls for heat, power is supplied to the igniter, then after a certain amperage draw on the igniter, the gas valve is energizes to open and allow gas to flow starting the flame. As long as the amperage draw on the igniter is high enough then the gas valve stays open till the thermostat is satisfied.

Sometimes the igniter will crack and no current will go through and the igniter will not even heat up or glow. Sometimes the igniter will wear to the point where it will still heat up and glow, but the current draw will not be high enough to allow the gas valve to open. This creates a confusing situation where you look into the oven and see the glow from the igniter, but get no heat because the burner never lights up. If this is the case then you will need to replace the igniter even though it seems to be okay. The only way to know for sure is to know what the current draw requirements are for that gas valve and to have an amp meter to check the current draw.

Most of the time the problem will be in the igniter, and not the gas valve. Gas valves can go bad, but that is the case in only a very small amount of the situations. It is a pretty safe bet that if you have a problem with you gas oven lighting that you have a problem with your igniter.

Oven has worked on and off for the last year, now doesent work at all, i have the igniter exposed and it is glowing red, you do not smell gas at first but after about 2-3 min you begin to smell the gas,...


If your unit has a separate gas valve for the oven burner, that would be my first guess. But I would also check to make sure that the thermocoupler was not corroded, coated or defective.

Oven glowplug lights but gas will not turn on oven, broiler works fine. have replaced gas valve and circut board


Even though the ignitor (glowplug) is heating up, it more than likely still needs to be replaced. They do become weak over time. An oven gas valve requires a certain amount of current moving through the coil in order to open the plunger. The he circuit goes through the ignitor, and the hotter thee ignitor gets, the more current flows through it. As the ignitor weakens, it does not allow sufficient current through the circuit to open the valve. Replace the ignitor and you'll be baking in time for Thanksgiving. Use caution when installing the ignitor, as they are extremely fragile. Also, do not touch the actual element section of the ignitor when installing it.******Remember to remove power from the range before making this repair.
Good luck, and gobble, gobble.

My Amanda gas oven Model no. AGS781WW is not heating up in the oven, nor does the broiler come on. The electronic ignition glows, I don't smell any gas in the oven. The cooktop comes on fine.


even if the ignitor glows it may not be getting hot enough to light the gas. if it does not get hot enough the gas valve should not open. try changing the ignitor, usually 30 - 60 dollars.

Igniter comes on but gas won't light


It should glow almost a bright white. If its just an orange glow then replace the ignitor. Its probably just weak. If its weak it will not allow enough current to flow through it to open the gas valve. Good luck _MJ_

I replaced what I thought was a bad igniter.But still had no glow from new igniter. Must be something else.Where do I go from here?


Hello there: The oven bake burner and ignition components are located beneath the oven cavity. In most cases the oven bottom panel can be removed for access (check your owner's manual) but on some models the oven burner has to be accessed from below in the warming or broiler drawer area. If accessing from the top, a 'flame spreader' (flat metal plate) above the burner may also need to be removed to see the burner itself.Many ovens use a single oven burner in which case they only have a single gas valve and ignitor. The same burner is used for both bake and broil functions, the broil usually being in the drawer area below the oven. Higher-end models may have a separate bake and broil burner. On such a system there will be two ignitors, one for each burner. They may also employ a 'dual' gas valve (see illustration above) instead of using a separate valve for each burner.Some range models may have an additional broil burner located at the top of the oven cavity which may be referred to as a 'waist high' broil. If not, broiling usually takes place in the drawer area below the oven, which uses the same bake burner for the broil function. Most gas ranges currently available employ one of 3 basic gas ignition systems; pilot ignition, hot surface ignition system (which uses a 'glow bar' or 'glow coil' - aka an "ignitor") and a spark ignition system. The latter two being referred to as "electronic ignition" systems as they use electricity in one form or another to operate the oven heating system. Only the pilot ignition system has an actual "pilot" (which is a small but real "flame") which might need manual lighting.
If the surface burners of a range are a spark ignition type, the oven IS one of the possible kinds of electronic ignition systems and thus will not usually have a "pilot" which needs lighting. Be aware though that just because the surface burners might light via a spark doesn't necessarily mean the oven uses the spark type ignition system too.
There is one older style of electronic ignition system which does also use an oven pilot but it is very rare and such a system hasn't been used in oven models since the early to mid 70's. It is the 'constant pilot' *electronic ignition* system.


Making Observations
The oven burner's operation will usually need to be directly observed while in operation as the first step to troubleshooting problems.Ignition System Type Links
Ignition System Types:
  • Pilot Ignition
  • Electronic Ignition with Constant Pilot (rare)
  • Electronic Ignition with Glow Ignitor (most common)
  • Spark Ignition System

  • Is there continuity between the oven gas valve's terminals?


    Hot Surface ('Glow Bar') Ignition System (most common)
    This is the most popular system currently used for ovens and is comprised of a control mechanism (whether thermostat or electronic control), the oven ignitor and an oven gas valve.


    What happens in this style ignition system is that the thermostat or electronic control switches power to the oven ignitor and gas valve circuit which are connected in series (one after the other). As power flows through the ignitor it heats and draws current (measured in amperage). Once the oven ignitor draws a specific amount of current the oven valve opens to allow gas to flow to the oven burner where the glowing hot ignitor (glow bar) ignites it. Power must continually flow through the ignitor and oven gas valve for gas to be released into the oven burner to create a flame.

    It should usually only take in the area of 30-90 seconds for the oven ignitor to reach the proper resistance to allow the proper amperage to reach the gas valve to open it and for the ignitor to ignite the gas at the oven burner.

    I have a Whirlpool Super Capacity 465 oven Model# SF315PEG. The bake valve was being energized but not opening to allow gas into the burner. Bought a new valve assembly P/N 3195008 and replaced. Problem...


    The ignitor is not allowing enough 'current flow' to open the valve. The ignitor , even if it glows, can be 'low current' to valve.

    Oven won't light, even with ignitor getting red


    If your oven won't bake, check these:

    Bake igniter
    Other causes
    Bake igniter Usually when an oven won't bake, 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.

    Other causes Other reasons that your oven may not bake are:

    • The clock settings are incorrect (if you have timed baking or a self-cleaning oven).

    • The thermostat is defective.

    • The safety valve that prevents accidental gas flow is defective.

    • The selector switch is defective.

    Amana arg7800ww oven will not come up to temperature.


    Your gas valve has a thermocouple circuit that will not let gas flow until the ignitor is hot enough. A failed ignitor can still glow but not be hot enough to open the gas valve. Replace your ignitor.
