My oven SCHEMATIC...for new oven builders..

[FoxRider1488]

that is a nice controller...how much does it cost to make one of those?

[kcenicola]

Since each one of these is made to the customers specifications regarding length of power cord wire, number and length of element wire, the prices vary due to this variation in quantity of components and material. This particular controller was $327. Versions with less features and length of wires have run as low as $228.

Can I ask where the amp meter is in the schematic? Would it go in the 240 line before the Contactor or after. Or does it matter? Also, I'm installing two fusses in the 240 line before the contactor. And one on the power line into the digital controller. Don't want to have to replace this stuff because of a surge.

[kcenicola]

The ammeter measures the total load on the controller (both elements, fan & light) hence it is wired in series on the one 120 leg that the fan and light draw from before the relay/contactor.

This unit is also fused. A ceramic time delay fuse is used for the fan load and a fast acting fuse is used protecting the controller.

call me dumb if i'm wrong...but that schematic won't work. the only thing that is grounded is the fan and it will be on all the time w/o a switch to cut the power.

I think the item marked "FS" is the fan switch.
He probably has the ground secured to the oven and/or the control panel.
Shouldn't there be a neutral on the contactor somewhere?

[autobonifica]

exactly...that's only part of what i mean

I tried to argue that exact point (about the missing neutral) in the 9th post of this thread ,Here is my dilemna ( with pictures !) but as you can see they say it works, however I still don't see how.

I wired it per instructions that came with contactor & controller. Ive been using my oven daily for last 5 months wired just like my schematic. works great & no problems at all ..

I believe you, but it must be drawing neutral from the grounded oven.
