    I have same problem with a CGR3742 model. ignitor comes on but no gas until I smack it. The valve is a dual valve feeding oven and broiler. My broiler side of the valve still works. And since the ignitor and valve are on the same circuit, they are both getting power. I'm going to order the valve.

The problem is not fixed, but I know it involves replacing the ignitor and/or the gas valve. I just wanted help diagnosing the two so I only had to buy one part if I could. We live on a budget and if I could avoid replacing an unnecessary part that would help. I am afraid your elite people would just tell me to start with the ignitor and then the valve.

Thank you just the same.

Whirlpool oven wont start, is there away to light the pilot?


You don't say what model you have. That being said, I highly doubt it uses a pilot light. It most likely uses a glow bar igniter to ignite the gas. Take the bottom of the oven cavity off (remove the racks and you'll see a couple screws in the back on the bottom. Remove those and the bottom of the oven cavity should lift up).

Once you have the bottom cover off, turn on your oven and watch the glow bar. If it glows bright white, it's good and your gas valve is most likely bad. If it doesn't glow at all, or it's not very bright, or it has one bright white spot on it and the rest of it looks a little yellowish orange, then you need to replace the glow bar igniter.

Anyway, that's where I'd start.

Good luck!

Kenmore Oven


I am sure you will just have to replace the oven igniter (glow bar) These will crack and not let any power through the oven valve.

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:--

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

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.

I smell gas when I turn on my oven. I replaced the gas line but have the same result.


Your Maytag wall oven is equipped with
pilotless ignition. Heat from the Glow Bar
ignitor lights the oven burner. With this type of
ignition system, the oven will not operate
during a power failure or if the wall oven is
disconnected from the wall outlet.

if it is plugged in and everything, your glow bar may be broken, which would mean you will either need to replace it, or get professional service.

Oven takes too long to heat up sometimes wont even go to the temperature ignitor is working well can see the glow magic chef model 3488vvv serial 13368882kz


Hello there:
Hi,

When you turn the oven on, open the oven door and look down at the bottom and see if its glowing red, it should glow red for about 45-60 seconds then you should hear the gas ignite. If the gas doesn't ignite, then your igniter glow bar is bad.

Here's the oven glow bar igniter for your model:

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.

    The oven burner will not ignite.


    Because the glowbar is glowing does not necessarily make it good.
    Turn off the gas to the stove. Remove the oven racks. Remove the bottom oven pan. Remove the flame spreader. This gives you access to the glow bar and gas valve.
    Put a clamp on amp meter around one wire of the glowbar. Turn the oven control on to BAKE.
    If the glowbar reads 3 amps or less,replace the glowbar ignitor.
    If the glowbar reads good,check the burner tube for a white ash buildup. It can be cleaned with a wire brush. Look closely near the glowbar section of the burner.
    Check all the wire connections for the gas valve.
    If the glowbar is good and the ash deposits are gone and the oven still will not ignite,the next step is to replace the gas safety valve.

    Glow plug comes on bright orange but does not ignite gas.


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

    Broiler works, as do burners. The oven will not come on. Gas whirlpool range 2003 year. Model SF367LEKB


    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.

    Oven won't heat


    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
