Oh how I praise God this happen when my in-laws were here! I would have had NO idea what to do. Though I'm smart enough to know not to put water on it, I was told that a fire extinguisher wouldn't have even helped if I had not turned off the breaker. How in the world would I have known that?! My father-in-law was already able to fix the oven (he's such a handy man and knowledgeable in all that's electrical). Needless to say, it was a bit of a scare and I praise God it was a much smaller issue then it could have been. I was told that any time an appliance is on fire to immediately turn off the breaker before anything. Obviously I can call the fire department as well, maybe even on my phone on the way to the fuse box. I pray this tiny bit of knowledge is helpful for you too!
Praise God for grace in our lives once again!
