Top oven (Convection oven)...upper and lower elements will not heat. Went to turn it on tonight, set it to 350 to bake and elements didn't come on at all. Panel appears to be working fine, fan in convection oven comes on, light works, lower oven works fine. Are the upper and lower elements in the convection oven connected together? Could it just be burned out elements? Nothing has happened between last night and tonight...last night everything was fine.

Re: Elements in convection oven won't heat
DO you have a model number for that. I'm almost sure it's a thermal fuse in the back of the oven. Usually they go out during or after cleaning but that would shut down both elements. If you have the model (usually by the inside door look all over and up in the cavity) Then if you go to this link
a 6ya expert can help you resolve that issue over the phone in a minute or two.

If you ask how many heating elements is there then my answer is two. Upper heater element with grill heater (1000 / 1900W) and ring heating element (2400W) that is positioned around the convection fan.
I have a DACOR double electric oven model ECD230SCH. the top oven lower element went out 1 and 1/2 years ago, but the top element broiler works. Yesterday the bottom oven did the same thing- bottom element not working along with convection. Pulled off doors and cut breaker. Checked thermal switch on top off oven- closed good. Pull out element and Ohm'ed out- good. Now pulled over and out oven top panel to get to the control boards. Found a nice set of schematics for the over control boards and electronics. Sat down and pin-pointed both relays that supply power to upper and lower oven "lower" heating elements. these are on 2 different boards- upper over relays on bigger board on the left with the transformer. Lower oven on the right smaller board. Hardest pain in the rear was just getting the little plastic stand offs to push back through the board to get it off. Finally got it off and inspected board. Low and behold the relay I pin-pointed had a burn/open connection on the solder joint. Re-soldered tested oven and lower oven lower heat element works now! Went to the next board and got that off and same exact problem on the rely for the top oven lower element. Re-solder and test- good!! Put everything together and ran over to 350 on top and lower and back to normal. Wife very happy she did not have to pay a repair man big bucks to swap out the control boards- would have had to replace both.
I have a degree in electronic technology so as a technician for many years did low and high voltage component level repairs. But pretty easy and you can visually see the open solder joint on the back of the board at the relay leg.

Hello Michele Smith - If neither elements do not heat but the top of the unit works, then they can possibly be faulty elements or connection. However, if you are experiencing other performance difficulties, then you may have a bad control board that needs to be replaced. Consult a professional for an accurate diagnosis.
what is your oven if is gas or electric, if is gas easy to preheat by using lower heating element, if electric? that your unit have convection? or not? coz some probelm of the oven is, 1 if the oven is no convection or your oven is single heating in upper element,if your oven have a timer and cut off in 15minute? dont use timer,use a manual timer by it your self,if you want to reach the degrees that you want check your oven if der a lower and upper heating element with convection function,that the one is the most easy way to reach the degree that you want to reach.
THIS SOUNDS LIKE THE ELEMENTS HAVE BURNT OUT TO FIX FIRST TURN OFF THE POWER THEN LOCATE THE SCREWS HOLDING THE PANEL INSIDE THE OVEN REMOVE ALL SCREWS AND PANEL THEN REMOVE THE ELEMENT FROM ITS PLUG CONNECTION TAKE THE ELEMENT TO A ELECTRIC AND PLUMMERS SUPPLY STORE REFIT ELEMENT AND YOUR OVEN SHOULD WORK FINE .
With all that you said, I would suspect an open or faulty element. It is pretty much the most obvious solution.
If you have any electronically ability and you are going to open the oven, use an ohm or resistance meter, check the amount of ohms and use the upper element as a reference for the correct reading. The element will either read open or good. You can use a light tester also and if the light lights between the two connectors of the elements, then it is ok and look elsewhere.
The control switch may be bad on it. If there are 2 elements on the top, they both are not bad at the same time.Check to see if the wires have not burned off the control switch first. Check to see if your breakers are O.K. Turn them both(maybe 3) off and then reset.
this could be due to more than one cause
selector switch faulty
elements faulty. however this would mean both elements gone - there is one at the top and one at the bottom
also worth while looking at the wiring to the convection elements.
does the thermostat neon come on when convection is selected?
