Hey, I was just thinking about those classic “three switches, one lightbulb” puzzles and how they’re almost a blueprint for troubleshooting. What if we set up a similar scenario but with a real broken gadget—like a toaster that only gives one error code at a time? We could try to deduce which part is causing the problem with the fewest tests. Sound like a fun logic challenge for both of us?

Sounds good. Let’s list the error codes first, then assign each to a potential fault—like code A could mean a burnt‑out heating element, code B a faulty thermostat, code C a wiring issue. We’ll test one at a time, note the result, and narrow it down. Once we’ve identified the culprit, we’ll replace or repair that part and see if the error clears. Ready to start?
