What is error E05?
I tested almost everything in this oven, but I never had a manual or documentation for the BOV800XL /A. The thermal fuse was continuous, the transistors, triacs, variable resistors, resistors, capacitors, etc. seemed fine. I did not check the transformer or relays. Here is a link to a version of the manual that vaguely describes the errors on page 54. My continuity test showed that the old oven sensor reads at about 125 kΩ at room temperature. Other sources say it should be in the range of several thousand ohms. Any suggestions/sources for E05 error code?
Ist dies eine gute Frage?

@nathantafelsky E05 should be a failed Triac

If it read at 125kΩ then it might be a faulty sensor. A functioning oven sensor should read in the range of several thousand ohms at room temperature,

@oldturkey03 Both triacs had the same resistance across their anode-to-cathode, I think the triacs are fine. They don't show any signs of overheating, and current only flows in the direction it is supposed to.

Successful update:
I replaced the temperature sensor, and now it works. It actually threw the E05 error once or twice shortly after replacement, then never again. The sensor itself looked exactly like the old one. The wire connector was wrong (black, not white and wrong shape), so I soldered the old one on with heatsink. I assume it is a resistor and therefore works in any direction.
Then I began testing.
I was able to cook toast (the default setting, medium, 5 minutes). Then, I did it again and then the E05 error was thrown. I unplugged the oven, held the power button for 15 seconds. I tried one or two other settings. I was holding my hand on the triad head sinks for the first few tests. They can get too hot to touch for 10-20ish seconds at a time. Shortly after, the E05 error was thrown again when I was tapping on the relay (seems to directly affect Start/Cancel).
I ran it on various high settings like largest frozen pizza, 20-minute roast, et cetera and it has not thrown the E05 error again.
