Howdy all,

I just bought an older model 1400 and cooked my first brisket. It went well, but i have a question about the fluctuation in temp.
I understand the 1400 uses a analog thermostat that turns on and off the heating element.
I'm fine with the 10 degree or so "wave", but it seems that the temp gets hotter and hotter each wave.

See the image below [and attached]... the wave increases and increases the longer the heat. Is this normal or is there something wrong.

I really don't want to go digital, too much is digital these days .
