BOTTOM ELEMENT DOES NOT WORK
If the top element is working, then it is either the element, the wiring harness , or the control board.
Since both elements are controlled through the same temperature probe, then the temp. probe should be OK.
The heating element must be removed and tested using a multimeter.
The part is tested disconnecting wiring from element contacts, setting a multimeter to read impedance at Rx1, and reading Ohms on element contact.
If the circuit is open (no continuity and infinite Ohms value), then the element has blown and must be replaced.
If the element has continuity, test the wiring harness, then replace wiring harness or control board.
All the test must be done by a trained repairer, strictly observing all health and safety rules.
SAme problem.. Don't know how to fix.. Ruined pizza.
I too lost my lower elements a couple weeks ago. The front one had a 'hot-glow' spot one day (perhaps from something that dripped on it?) and then the lower elements stopped working. I assume all I need to do is fine one good element to swap for the bad one and I'll be back in business. Now, it's just a matter of finding that part! Anyone have any ideas? I'm thinking of posting in Craigslist about it, and emailing others w/ similar problems or who say their oven died (hoping they still have it and would be willing to part it out (preferable) or part it out just for the element(s)). I'd rather try and fix it than go out and buy a whole new toaster oven since this is less than 2 years old!
Only the top two elements work. This was an expensive unit. I would like to know how to fix it but this website is complex to see how to find the solutions. ****!
When I turn the warmer on top tray comes on and after reaching the temp of 150 it quits working. Bottom tray is working fine
