I'm converting a 1500W toaster to a reflow oven with PID control, but I'd like to focus on the hardware aspect.
I've pulled the switches and controls out of the oven and I'm left with something like this as if the oven is in bake mode which is all heaters and the convection fan:
At the bottom is the "new circuit". Is this a "good circuit" for the controlling the top and bottom heating elements? Anything to look out for? I'm open to suggestions for improvement of the design as well.
I'd like to keep the convection fan intact as to keep the top and bottom more evenly heated.(It's a shaded pole motor like this)
I'll be using all of the correctly rated hardware electrically and thermally speaking. Heatsinks and cooling fan will be used on the SSRs.
Update: The second, modified, circuit with the SSRs works.
