Elements in convection oven won't heat

Isn't the upper element the grilled? I don't think it is controlled by the oven thermostat.

I have attached a link to the service manual, there are relays that control the elements. https://www.manualslib.com/manual/703000/Dcs-Wo-227ss.html?page=42#manual

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.

Unscrew the handle and screws at the bottom. Carefully separate the outer panel from the frame

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.

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 .

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.

Bake- Normal convection- both upper and lower heating elements.

Conv. Bake- Semi-forced convection- both upper and lower elements, heat is then distributed throughout the oven via the fan.

Broil- radiation- The heat is radiated by the ifrared broil element.

Broil & Fan- Radiation and Ventilation- The radiated heat from the infra-red broiling element is distributed throughout the oven via the fan.

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?
