So I have been using an apartment sized electric range oven in my shop for duties such as coatings. It's been a great tool! I love having burners and oven. But I was always a little suspicious of the temp accuracy. So today I drilled a hole in the door and placed a lead thermometer (also had my non trustworthy IR gun handy). Turned on and was surprised that temp seemed low, very low. It was cycling on and off at about 300°-325° While set to 400°. So I cranked it up and finally got 400° at setting of 525°. But then it started climbing. Eventually I had backed it down to 400° on the knob and had a stable 400° on the thermometer. So, what I learned from this is that just because the oven is cycling on and off doesn't mean that it is actually at the set temp. The oven needs to heat soak for about 30 minutes in my case.
