My electric oven is in dire need of cleaning. However, I am rather terrified of doing the job. I'd feel much better about it if I could cut the power to the oven, but if there's a 'plug', I can't find it and my circuit breaker panel is not well labelled. My apartment complex recently upgraded the fire alarm system and currently if I turn the oven on over 400 my fire alarms go off (no smoke is visible). There's some gunk at the bottom of the oven I assume is responsible. I can't use the auto-clean cycle because it will set the alarms off. Any advise on how to safely clean my oven would be greatly appreciated!
