Re: My 3'x3'x6' Oven project.
Skip that fan for recirculation. It's ok for a vent fan but won't take extended heat cycles because the housing isn't completely closed and the fan drive is made of rubber. I tried these and have since pulled the one I had as a recirc.
The PID comes with a TC so unless you need the extra length of the one you posted, you can skip it too.
The timer? Well, unless you're going to use it to make coffee I see no need for this type in an oven. It turns on at a specified time of day so I'm confused about why you included it.
Add a heat sink to your list!
