Can someone tell me about temperature control and thermometers?

    I have a gas oven with a convection fan and when it gets up to temp, the light goes off. This is with the convection fan running. If I look at the portable thermometer in the oven, it is 25-50 degrees below target.

    The oven is only a year old so I think it is functioning correctly, but my wife is mad because all of her recipes are undercooked and hard to control.

    What is the proper way to manage an oven like this? Would longer pre-heat times help it be more consistant?

    For the record, we open it as little as possible to keep the heat in.

    The oven automatically lowers the temp when baking in convection mode I believe...at least that's my understanding on ours...

    I will look into this. This is the first I have heard of this.

    It probably needs to be calibrated....lots of info on the net

    Thanks, I didn't know this could be done.

    At work we have a convection oven and it seems to cook hotter if it is engaged. I usually drop things 25 or more degrees when using it but usually I just keep it off so it bakes more like at home. Both run on natural gas. Might just be this one that runs hot, it is a $3500 pro model, Thor if I remember right.

    That's funny. It isn't the commercial version, but I do have a gas Thor. Even with the convection on, mine is running 25ish too cold. If it was the other way, I would be expect it. I didn't see any adjustments in their manuals and I sent them a customer service message but they never got back to me.
    I like the range but silly stuff like this leaves me cooked! :picard:

    The oven eventually stopped working entirely. I spoke with Thor a number of times and it turns out that the igniters in the oven and broiler were both expired. Thor replaced them both, just barely under the warranty time out. The service tech said that the sign they are going to die is when they take longer and longer to ignite. Then finally, they just die. The stove still runs about 25 degrees cooler than the gauge but at least it is working again. I can make adjustments for the 25 degrees, but, for the price of the stove, I am not sure I should have to... :confused:

    Any reviews or comments regarding the internal oven temperature sensor? Maybe it’s prone to failure like the igniters (or just defective to begin with)? If it is accessible by the homeowner maybe pull it and test for factory spec’d resistance?
    Or- run it with another standalone thermometer to check the accuracy of the one you currently use?

    Yeah, the resistance of the igniters is supposed to be 3. (Volts?)
    As far as the thermometer. I have a regular oven thermometer inside the door that says temp is consistently 25 degrees under. The book doesn't give a way to fix the issue. The help center didn't respond for 3 weeks.... It might still have an issue with the internal thermometer, it is hard to tell.

    Resistance is measured in ohms.

    With a good old electric stove, you just turn it on, put a thermometer in it. Pull the temp control knob off, and put it back on to whatever the temp inside is! Primitive calibration! (ahh... the good old days..)

    Gas stoves are the same. You can move the knob a few degrees to make it match. There are screws on the back of the knob where you can loosen the locking mechanism.
