This person was arguing with multiple people about how electric is superior to gas. In an effort to prove me wrong about how electric cooktops work, they posted a wiring diagram for an oven thermostat.

Update : after their snarky reply, I looked closer at the manual they posted, and it’s for a stove with gas burners. So even if they were right, that component wouldn’t exist on that particular appliance. It would indeed produce a steady heat though.
