Whirlpool gas oven "low" heat

10 posts in this topic

My Whirlpool gas oven seems to ignite within a reasonable period of time, however, the temperature will never get above 300-325 degrees no matter how long it stays on.  Opening up the broiler drawer to take a look a the flame coming out the burner, I noticed it barely is coming out and really isn't even reaching that plate directly above the burner. 

Reading through all the online help forums, this doesn't seem too typical of a bad ignitor.  Seems like when those go bad, they'll never ignite, or take a rather long time to do so. I thought the gas valves are either all the way open, or all the way closed, depending on the current draw through the ignitor.  I'm leaning toward replacing the gas valve.

Any thoughts/advice/nuggets of wisdom on this?

Are the top burners doing ok?  If so sounds like not enough gas getting to the oven burner for some reason.  The flame should go almost all of the way up both sides of the spreader.  Either you have a gas line stopped up, the orifice is clogged, or the gas valve is going bad.  Turn the gas off to the stove, and remove the gas valve to see if something is clogging the valve, or lines to and from the valve.  Also remove the burner to see if it is stopped up with gunk. The manual valves have a gas adjustment nut on the top of the valve, but do not remember is the electric ones do or not.

Another thing to note is this problem doesn't happen all the time.  Many times, everything is perfectly fine, with the flames all across the spreader. 

The top burners all behave okay.

sounds more like a failing ignitor,not drawing enough current to fully open gas valve-not an uncommon failure by any means- replace the ignitor.

If the igniter was not opening the valve all of the way there would be a gas smell from the oven.  Have you smelled any gas when it is doing its low burner flame thingie??  To be safe I would replace the ingiter and the gas valve...

There isn't a gas smell at all, so whatever gas is being passed  is being burned up.  I'll try swapping out the igniter first off, since that is about the easiest thing to replace.  

The other weird thing is most parts catalogs on the internet point me towards the round type of ignitor.  The one installed in the oven is clearly the square type.  I took a close look at it, and it resembles the square ones.  Do manufactures always use the same type, or can they mix and match these, assuming its matched up with a valve that will work with the ignitor?  This part hasn't been replaced before at all, so whatever is in it was what the factory put in it..

Hold on, your oven has a gas valve combo, the valve has a built in regulator attached to the valve, something I have not seen before.  I cannot see the igniter causing your problems without gas escaping into the oven..  I now suspect this regulator attached to the gas valve may be not letting enough gas into the valve at times.  The flat and round igniters have to match up to the valve by amps and voltage and have to be exact.  Your ingniter is  3186491 and the gas valve combo is 3195008. Your flat ignitor might be replaced by the W/P round igniter but does not show it crossing over to this in the parts page.....I had not mentioned the gas regulator earlier because the top burners work ok and the regulator is uaually where the gas line hooks onto and feeds the whole range.  This is the first time I have seen a regulator as part of the oven gas valve.

A new ignitor arrived yesterday.  I swapped it out, and the oven now works like a champ.  I fired it up a couple of times yesterday, and today as well.  The oven ignites after around 30 secs after turning it on, and I now have a nice blue flame extended just about all the away across the spreader.  Go figure....

I was surprised how easy it was to change out.   I was expecting the oven to put up much more of a fight!
