Will my coffee maker burn my house down?

I left my coffee maker (Mr. Coffee, switch model) on with about a quarter pot's worth of coffee still in it. I won't be back home to turn it off for 3 days. It sits atop my microwave. How worried should I be of it starting a fire?

You will probably come home to a cracked coffee pot or possibly one that shattered. Almost all the newer models of coffee makers (and irons) have automatic shut-off features now--might be worth the $30 investment to have that piece of mind.

Well...I've never left one on for quite that long, but I have let it go for like a day and a half, and it smoked and stunk up the house something awful. I will state the obvious, that if anyone has a key to your place, they should go turn off your Mr. Coffee.

does it not have an automatic shutoff? most do, these days.

If it doesn't have automatic shutoff, you should be very worried. The apartment below ours left their pot on overnight, and by the morning there was a fire. The smoke smell was terrible. Please, get someone into your place to turn it off.

My 10 year old Mr. Coffee shuts off automatically after 2 hours. Given the downside, I think I'd definitely have somebody check on it if it's possible, but odds are you probably have an auto-shutoff. It's a fairly standard feature exactly because people forget to turn them off!

I have had used a Bunn industrial, 4 burner machine that had no shut off. There was a small amount of coffee left in the pot, burner on, for a day and a half. It turned to sludge in the bottom of the pot. The pot did not crack. There was an odor of burning coffee but no smoke.

So, I suppose if there is a quarter pot of coffee, it would take a while for it to evaporate. As said prior, most every new coffee pot turns itself off in about 120-180 minutes to prevent just this situation.

Years ago I met a homeless guy living on the streets of Norfolk, VA who told me the story of how he became homeless:

He went fishing with a friend one morning and left his Mr. Coffee on. When he got home in the evening the fire department was dousing the remains of his single-wide rental trailer.

He said specifically, "If you have a Mr. Coffee, make sure to turn it off."

So... I'd take the homeless guy's advice and find a way to turn it off.

And maybe switch over a French Press.

If you haven't been contacted by the local fire department yet...

Couple of decades ago I worked in an office with one of those Bunn coffeemakers. It was pounded into us that you always turned the thing off after 4:00 p.m. or so.

Eventually someone forgot on a Friday afternoon. It stayed on, with about 1/3 pot of coffee, until Monday morning. Pot was scorched and ruined, break room stank for a week, employee responsible was subject to merciless ribbing. Beyond that, no harm done.

This may or may not correspond to your situation.

I have left a small amount of coffee in a crappy pot (with no auto-off function) overnight, at my office, and returned in the morning to find the bottom of the pot encrusted with steaming sludge. I would not want to find out what would happen over three days (but I doubt it's enough to cause a fire).

My uninformed, entirely gut-based intuition is that the heat from a coffee pot warmer is not enough to start a fire.
