PID with convection Oven

[Rich22]

So I am about to finally hook up my oven to a PID. How do you deal with the convection fan with the PID so it continues to run constantly? Hook it up to constant power? If so what is the best way to do this. Casting pot seems easy by comparison.

Thanks

Yes, you run the oven light and the fan to a separate cord so that it has constant power instead of the pulse from the PID. Just pop open the case on the oven, and wire the fan and light out to a new (I use a salvaged) lamp cord and plug. Your oven will look odd with two electrical cords, but it'll work great.

Bump.

What do you do with the cooling fan if the oven has one? Just leave it out?

I ran my lights and fan each with a seperate on/off switch.

This is a real convection oven so the fan is blowing hot air,it has a circular heating element. Then there are both the usual elements,up and down. The fan is blowing all the time,sometimes hot,sometimes not.

Then there is a cylindrical cooling fan that works together with everything else. Temps are holding pretty good but with a PID it might be better. I thoght it was radiant heat that overheats the bullets but actually it's the hot blowing fan. What if I only PID the element for that fan?

I may not use this exact oven,my coatings are good. But there are lots of similar ovens around,these 2kW wall ovens cost like 1500€ new and used ones sell for 50€. Some people change kitchen furniture like fashion.

This is my 30" wall oven I got from a neighbor for free; the board on the all digital was bad. I have both 220 v elements with an on/off switch. as well as the 110V. The lights fans PID and timer run on 110V and switched separately. I also installed a cooling fan for the relay.
If I am going to preheat the oven or heat other objects to spray coat I can switch on the elements and the fans. I can switch on the PID to observe the temperature and lights if I wish. i can switch on the timer to control the process if desired. Wired in this fashion has worked well for me as I also coat other objects other than bullets.
