    We recently got a new electric oven/stove.  Have used the oven a few times but not too many times because the oven has the option to be either a standard oven or convection and since we're not too sure what the difference is we haven't used it much.  Anyway the other day we turned on the oven to "Bake" and waited for the beep to tell us it had reached temperature.  It never beeped or generated any heat. I turned it off and tried several other of the oven functions ("Conv Bake/Broil/etc) and the oven would not heat up although all lights etc lit up as normal.  I went outside and flipped the breaker off, then turned it back on.  When I tried the oven again it was the same.  After some time I decide to turn off the breaker and leave it off for a few minutes.  After about 5 minutes I turned the breaker back on and the oven has functioned correctly ever since.  Could there be a problem with the breaker?  House is almost 40 years old and I'm pretty sure it is the original wiring/breakers/electrical.  Any ideas on what could have happened?  Thanks for any ideas.

    I don't think you have a breaker problem., It sounds like an appliance problem where a power on reset temporarily fix the problem.

    Appliance make and model will help

    You bought a dual purpose oven - convection and standard - and haven't read the instructions enough to know the difference? The oven malfunctioned and you didn't check the instructions to see what the problem might be? Try reading the book that came with the new oven.

    Racer -What's with the snide comments? Manuals that came with it don't mention anything about this type of problem. Stove was new to us not brand new. We bought it from someone who's house was partially burned in the last wildfire we had here and the insurance company is giving the people we bought the stove from a new kitchen. They had purchased the stove about 3-4 months before their house caught fire so for all intents and purposes it is new. Do me a favor and don't reply to any of my posts if yor're going to be such an a**hole.

    Ya know JK, I'm with WoodWizard on this one.

    These darn computer controlled appliances should have a master reset button like we have on our computers to re-boot them.

    Just speculating here, but some noise could have been on the power line or some sort of unusual event that caused it's on-board computer to malfunction. ( All new appliances have some sort of computer control, maybe its not much more than that of a calculator, but a computer never-the-less. ) You turning off the breaker for a period allowed it's power supply to completely drain off and when power was applied again, it "re-booted"!

    Prolly' the best thing anyone could have done.

    Still I would watch it for another hiccup, if it happens again, then there may be a fault in it's electronics or something else that is causing it to forget how to bake.

    As an aside, you are sure that it was wired correctly when it was installed and that your home has a good earth ground from the circuit breaker box. A faulty ground could have "possibly" caused the problem.

    Also, it may be an unknown (undocumented) feature in the computer control. Something that would detect an unbalanced power input with reference to neutral and shut things down.

    Keep an eye on it my friend.

    JK,

    Please tell us whether the breaker is a true two-pole breaker (with a single handle) or if it is two single pole breakers with a handle tie.

    A convection oven uses air movement to cook foods quicker than a standard oven. I don't know the answer to your electrical problem.

    JK, just a thought you may be able to access the manual online by entering the make, model and so on it may even give you a schematic to help you identify all the components. Good luck.

    I would consider moving the stove out and checking any and all power connections, such as where the cord is connected in the stove and in the receptacle that should be mounted low on the wall.  The symptoms you describe are those that could result from a loose / intermittent connection.  If that is the case, it could be a fire hazard and immediate repair is required.

    breakers come with 2 different phases, a magnetic trip that trips the breaker with you short something out or have too much current going threw it, and a bimetal trip that trips when gets too hot or is overloaded for long period of times. ovens also come equiped with their own overload protection then will trip when it get too hot. the good thing about this is once it cools off you can reset the breaker no damage caused.

    my guess is your breaker or even the oven itself has an overload protection the tripped causing it to shut down your oven, but once givin the chance to cool down was working again. odds are this happened because you used the clean option on your oven or you dont have the right size breaker or wire installed.

    We installed a range in one apartment six months or so ago. Range had the touch pad control. Range worked a couple of times than the touch pad would go screwy. The buttons did not do as requested. So I called the service tech line and was told to unplug the range and after a few minutes plug back in. It has worked fine ever since. Ken...

    This unit was in a fire?

    Any smoke or heat damage?

     Are there any FAIL CODES on display before or after malfunction?

      Model # would help to get a better idea of what could be causing the problem.

    Over the years I have seen all kind of ghosts.

     Cordless phones,security system,to burning a turkey to cause an unwanted command to the unit.

    OPPOSITE of what is selected.

      Moving it in and out of the house could loosen the connectors on components.

     Going over it with a fine tooth comb may help.

     Put some convection info on here.........................
