So this oven fan runs all the time as far as I can tell.  Living in a dry environment this just makes my house less humid and causes more static electricity.  Will likely have to run a humidifier when I use the oven to offset the dryness the constant fan creates.  Also the fan runs for a very long time after the oven has been shut off.  On average seems to run for about an hour. It’s not a very quiet fan either.
