First…have you read the instructions that come with the range? Just because you had a convection oven before, doesn't mean this one operates the same way.

If you have…It’s new. It’s under warranty. Call the store you bought it from, or call KitchenAid. Don’t go messing around beforehand, lest you void the warranty.

Trust me, I have read the manual. And yes, I am going to call them. I am not planning to open up the thing myself.

But I wanted to know if there is some basic troubleshooting or testing to do first, so when I get the repaircritter on the phone, if he or she says "Have you tried this?", I can say "yep". I also was hoping someone else has this range and can tell me if there is a way to know if the convection is working.

The people at the store are very nice, but their installer clearly had no idea how to work the stove himself, so I don't think I would call them. I have heard not so great things about Kitchenaid service people just giving up and saying they don't know, so I was hoping I could learn enough about common issues to at least have some suggestions. I also have had issues with the service people on my last range (a Wolf) assuring me that the thing was working right when it clearly wasn't, so I wanted to get some sense of expected behavior of this range so I know whether the serviceperson is right or wrong.

The fan turns off when the oven door is opened but there's no visual evidence of the fan running inside the housing at back of the oven cavity when the door is closed? Is there a door switch plunger visible that you can manually depress to briefly run it with the door open?

The fan is supposed to turn off when the door is opened, according to the manual. But when the door is closed, I cannot hear a fan. It sounds the same if the door is open or closed, and it sounds the same when the oven is on non-convection bake as it does on convection bake. I don't know what visual evidence would look like through the oven door window. If I can make it run with the door open, what would I see?

Motion of a fan blade behind the slots of the fan housing. Aiming a flashlight at it through the door window may help with the visibility. Interestingly, parts diagrams show an electric element around the fan for some direct heating of the convection airflow along with the gas bake and broil burners. The unit takes a 120v electric connection so that electric element can't be more than 1,500 watts (like maximum of a portable space heater), probably is 900 to 1,200 watts. I don't have direct experience with gas ovens but my understanding is that some (most?) gas convection ovens don't run the convection fan when the gas burners are on to avoid blowing out the flame.

This doesn't sound good. Yours is the same model that we are getting.

I know this is an old post, but we are having the same issue with ours, along with a few other issues (oven not getting to temp). Did you grt a resolution from Kitchenaid?
