I have a gas wall oven Maytag model # CWG4510BAB Oven will not ignite, the glow bar is glowing but it will not turn on the burners. At first it would turn on the burners after being on for several minutes but now it will not turn the burners on at all.Could it be that the ignitor is not getting hot enough to ignite the burners.There is odor of gas but not a strong odor.Thank you in advance for your help.

if the oven has a glow bar it,s not staying hot enough to keep the main burner on change the glow bar

Hi and welcome to FixYa, I am Kelly

Your model number was missing digits so I used this manual:

and if your unit is older this one:

Automatic Ignition

The oven burner is lighted by electric ignition. To light the burner, press the pad for the desired electrical function and press the INCREASE or DECREASE pad until the desired temperature is displayed. The burner should ignite within 60 seconds. After the oven reaches the selected temperature, the oven burner cycles off completely, then on with a full flame to keep the oven temperature controlled.

Both the new and OLD units use a glow bar for lighting the burner. Most likely your Glow Bar has failed: GE PN: WB2X9154

The Glow Bar is item 316 this link:

If the glow bar is glowing and you still do not get ignition respond here and we can go through troubleshooting.

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.

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:

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.

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.

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.

The JGRP17 (not a full model number) does not have a pilot light. It uses glow bar ignitors. Watch the burner at the top of your oven when you turn on broil. After a short time the glow bar ignitor begins to glow, and a short time after that the broiler burner should ignite. The same thing should happen with the oven burner under the floor of the oven when you attempt to bake. If the igniter does not glow, or glows and burner does not light, replace ignitor. (looks like part # WB2X9154)

In many cases, even if the igniter is glowing, the resistance may not be low enough to turn on the gas valve. The igniter has probably gone bad. ($50.00 to $90.00 for igniter)

more than likely your glow bar ignitor has stopped working or at least pulling enough amps to open the safety valve. The floor of the ovens come out may have a couple screws toward the back. take the floor out if a diffuser is on top of the burner remove it. the glow bar ignitor is mounted on the burner turn the oven on and watch it should glow bright red and in about 30 secs open the gas safety valve. If it does not glow you may want to verify power to the ignitor, more than likely the ignitor is the problem. If it glows but does not open the safety valev still replace the ignitor not pulling the required amps to open the safety valve. just put a little dish soap on the screws to the ignitor to help from srtripping them out
