Jenn air jgr8850adw won't bake

I have a Jenn air range that won't bake some times. Some times it takes 30 minutes for the oven to preheat. I checked the igniter an it works - it seems there is no gas coming thru the element. Could it be a problem with the gas valve? How do I check it? The brolier lights very quickly everytime.

    When it finally would start, the flow of gas would intermittant and often there would be poof sounds.

    I switched the two ignitors and now the bake works fine and the broil does not. In order to take the ign. out, the back plates need to be removed to unplug the broiler wires. Unless it is possible to pull the wires with connector into the oven.

    To remove both ign. it seems easiest to remove the whole burner. One screw for the top and two for the bottom. One screw broke in the process.

    My oven also takes a long time to come to temperature, 30-40 mis to 350 degrees. Then when it's at temp, there's a distinct mild gas odor when the door is opened - pretty scary. The broiler works just fine. I'll get that bake igniter checked out.



    I've read that if you use the clean cycle enough, the igniter is sure to go.

This usually is an indication of a bad igniter. If this is the standard glow type igniter, it could appear as if it is working, but may not be providing enough current to open the gas valve. This is a safety feature on gas ovens. The gas valve requires a current potential of .32 to .37 amps through the igniter before it will open and allow gas to flow. This prevents gas leakage if the igniter fails to light. The reason your broiler works is probably due to the fact that the broiler gets used less and the igniter is probably in better condition. You can test this theory, if you like, by swapping the igniter for the bake and broil burners to see if the symptoms change. Or, you can simply just replace the bake igniter with a new one. Make sure you secure the power before attempting, though. You shouldn't have to turn off the gas for this. Chances are that's all it is. I hope this helps you.

Model: JDS8850AAS -- Oven won't preheat above 150


Hello,

The problem beleive it or not is that the bake ignitor 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 ignotor 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

Hope this helps

My Jenn Air JGS8850 takes over 10 minutes to preheat to, say, 400*. Is this normal?


Hi,

In a word...Yes !

10 min. is actually a really great preheat time. I have many customers who would kill for that kind of preheat, most are between 15-20 minutes minimum to 350 degrees celcius, especially with the introduction of hidden bake elements in the last 10-15 years.

Hope that is helpful,

Good Luck :)

Put an oven thermometer in the oven on convection bake and check the actual temp inside. I'll bet it's not maintaining the correct temp in convection.

Preheating Oven


Cold Stove, you may not be able to. The issue here is that oven manufactures put on their units a fast preheat. However it isn't possible to preheat an oven for 7 to 9 minutes and bake short time bake items properly. Also the oven sensor will respond faster than the absorbation rate of the sheet metal in the oven liner. To preheat an oven properly takes 15 to 20 minutes before putting in the food. I see this will a lot of current ovens. Sounds like a normal format of the control.
