Range - Six months ago after baking, cooling fan stayed on all night. Someone (I found online) told me to experiment with Clear/Off (controls) button. Eventually it did shut off. Next time fan stayed on, no luck with the buttons. Killed the breaker and fan was off next morning. Have killed the breaker 6-8 times since to shut fan off (always after bake use). No problems with rest of the range, only the oven fan. From schematic I'm guessing stuck cooling fan relay, or the Fan Holding thermostat that's in parallel with relay contacts. Does this sound right? It's a hard-wired built-in.
Assuming I'm on the right track, where are the relay and thermostat physically located?
