THe ignitor seems to continuouslu try to ignite, but the oven valve will not open and let the gas out. The in-line gas valve is open so gas is available.

    THe least expensive option was the sensior probe. I will replace that tonight. If that doesn't work, I will try the two tests, the amperage and the volts. Thank you both. I will post the result.

On maytag units (household)you will need an Amp probe to see if your ignitor is working properly..yes it maybe glowing but it does not mean it is ok..the valve opens on the amp draw of the glow bar it should read a min of 3.2 to a max of 5.2 amps at full glow if you read in that range your valve is bad if not replace your ignit.

Eliminate the gas valve first--Use a meter and connect the 2 wires off the valve to it.turn the oven on and you should either read 120v or 24v depending on the unit.If you have the voltage but no ignition the valve may be bad.However if you dont have the voltage i would suspect the heat board or thermostat as an issue.I would also check the pilot/burner for a clog from soot,even more so if the units propane.Let me know

GE wall oven gas model # JGRS14 won't heat past 100 and I don't see any flames


if you can see the ignitor glowing on either the broiler or the lower area of the oven then the gas valve is bad and not opening anymore,sometimes the ignitors are the culprit as they are in series with the gas valve and if weak wont let the valve open,but both upper and lower burners not operating i would suspect a gas valve first

Lighter come on but burnner do not come on


Hello,
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 ignitor(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 ignitor make sure only one wire,either one and not both.
if amp draw less than 3.3-3.6 amps replace bake ignitor. 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 ignitor comes on yet the oven won't heat that a weak ignitor is the cause 100% of the time.

Gas oven will not lite but thing in bottom glows do not smell gas


By "thing in bottom" Iam assuming your talking about the igniter. If you are and it is only glowing then it probably needs to be replaced. If you cant smell the gas either thats a worring sign in of itself. I would first replace the igniter and then go from there though. Let me know how it goes!!

Oven bake ignitor glows but gas valve will not open until you tap on it. Broiler ignitor and gas valve work fine.

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 Frigidaire stove, model fgf316asa, and the oven does not heat. The ignitor still glows but does not ignite the gas. I cannot hear the gas coming from the line. What's wrong?


    Hi, You should change the ignitor. Even tho it glows, the ignitor is to weak to open the gas valve. UNPLUG the oven. Remove the floor panel in the oven and you sill be able to see the ignitor. This is very common with gas stoves.
    I hope this helps you. Please let me know if I can assist you further.

    Kenmore gas oven won't heat up


    If your ignitor is coming on that means the oven control is supplying the power to the ignitor and gas valve. So the gas valve is ok because it is allowing for a complete circuit so what the heck is wrong? The ignitor MUST draw 3.5 amps in order to open the gas safety and allow the gas to come out. The ignitor must be very bright, if it is dim then it is bad. (MORE)
