Crosley (Maytag) CG3478VVD Gas oven not heating properly
The glow plug runs properly and the gas comes on fully for about 10 - 15 seconds. It shuts down then restarts and the gas pulses for a short time then seems to run slowly causing long heat up times. The temperature seems very accurate once running and the display register seems accurate as well. I have guessed that the gas control valve is faulty but at $100.00 I don't want to guess. Thanks in advance.

It's possible but a failing (ignitor) can cause this too. It might be barely passing enough current to hold the valve fully open. Check the rating on the valve and then the current draw of the ignitor. Or sub in another ignitor. Also low gas pressure can cause it too. Have your utility co check for this

First of all, thank you for all your information. A rule I live by, even if an ignitor glows does not mean it works. The ignitor works on the flow of electricity through it not how bright it glows. If you can use a amperage meter, hook on one of the two wire to the ignitor directly. You need 3.2 to 3.6 amps to open the safety valve. If lower than 2.6 amps, it will not allow gas to enter the burner. If you have no clue what I am asking you to do, you can purchase and replace the ignitor and life will be better. P# 12400035. Its not difficult to change, the screws holding the ignitor in place sometimes strip out, when you get them off, you can replace them if needed.
can you hear gas coming in when you turn the know to "ligth" if not the you may have either a bad gas valve or the safety feature has detected something wrong, and has shut the gas off to the oven. first determine if you do indeed have gas., how does the oven light, is it pilot lit, or does it have a glow plug, if its pilot lit, make sure the pilot is running. if its a glow plug, you should be able to see it glow when you turn the oven on, if its not glowing it has to be replaced (or maybe the wiring has gone bad). either way that's where to start.
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.
Just because it glows that does not mean it is not bad... The ignitor is not working right and is going bad.... have the repair man replace the ignitor, or DIY.... Check out this tip about your problem...
Sounds like a sticking gas valve or a defective hot surface igniter. Open the broiler drawer or remove the bottom cover in the oven compartment. The oven usually has a hot surface igniter or a spark igniter. Turn on the oven and watch for the hot surface igniter to start glowing. It should glow very bright. Once it is glowing the burner gas should come on. If you hear the gas come on it should light right away. If there is any delay shut off the oven and stay back. Let the gas clear out then inspect the area near the igniter and make sure the burner is not plugged(the little holes may have debris in them). If you turn on the oven and the igniter comes,glows brightly,no gas is heard but you can smell gas it is either a blocked burner orfice/assembly or sticking gas control valve. Try giving the burner and gas control valve a tap and see if it comes on. If you tap the control valve and it starts working then shut of the oven and try it several times. If it starts to come on and off now you may have cleared whatever debris was causing the problem. If it does it again then it could be the control valve or a weak hot surface igniter. The igniter can be tested with a ohm meter. Most of the time when I get this complaint it is the oven control valve that is sticking. Be very careful when doing these procedures....gas can build up in the oven compartment very quicky and flash if ignited. Always have the gas shut off valve at the back of the range within reach and the electrical outlet in case you need to unplug it.
Doubt that the glow plug is bad. Gas only needs about 1100 degree F. to ignite using the glow plug method. It really seems as if there may be no gas getting to the burner. If there is no flame, you should be able to smell gas. If there is no gas smell, then I would look for the obvious such as: is the gas turned on?, Does the gas valve on the unit have a safety that is tripped? and so on. A new gas valve may be in order but make sure that it is receiving the proper voltage when the glow plug is on. Lastly, there may be a safety that is malfunctioning. If the unit does not light within a given time, the safety will "Lock Out" the unit so the place doesn't fill up with gas.
Hope this helps and good luck.
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
