Does this sound right?

Since the guy tore my entire furnace apart then left me holding the bag I've been trying to put it back together. I've installed the new pump, which I must say, is sexy. Ok, not really but it is better than the old one and fit nicely.

Now, I'm trying to re-wire it. I was an electrical apprentice for 5 years so I'm not stupid when it comes to wiring. But, I can not get a complete part number off of my White Rodgers Oil Burner Controller. The only numbers I am able to read off of it are Type 668 **1 (* denotes rubbed off numbers). Which leads me to believe it is a Type 668-601 control. So, according the the cut-sheet I've found the orange wire goes to the ignition transformer. The Neutral from the motor goes to the white wire of the control. And the black wire from the control goes to the other wire to the ignition transformer. The white (Neutral) pair go to the neutral wire coming from the junction box and the black pair go to the hot side (black).

So, does that seem right to you guys?

I attempted to call the J-Off that broke my furnace in the first place then went ahead and told me to take the burner out but wouldn't you know it? The a-hole won't answer his damn phone.

Which, is ok. Considering he told me the transformer, pump and electrodes are no longer available. And I've discovered Webster is still around and still making pumps, I found a place that also sells the electrodes for $14 a pair and the same place that sells the electrodes sells the transformer too.

It sounds like if you read a few more books and wiring diagrams you will be a better burner tech. than the guy you mentioned.

The wiring plan you described sounds logical.

Thanks. I hate waiting around for people to do things for me. He got me interested in learning more about it and so now I'm trying to learn as much as I can to do it on my own. I have every intention on buying that book from my other thread too. Just have to wait till payday. I work with my hands all day, on fire sprinkler systems so I like taking things apart and figuring out how they work.

As for my wiring. It seemed to make sense to me too. But, if I hook it up and fry the transformer and control or motor it'll suck to have to replace them too.

You could always go to your local supply house and ask to see a White Rodgers 668-601 control, then you would know if it is the same or not.

I didn't even think of doing that. But I did look at several different WR controllers from the 430 to the 601 and they all have the same wiring diagram. So, I'm assuming the way you wire them doesn't change much. I did notice however that all of the wiring diagrams are pretty vague. hehe.....

I drew up a picture of the diagram of how I interpreted the WR schematic. Maybe someone can see if I'm right or wrong. I also have a picture of the WR diagram too. I'll post both when I get home.

Does this help?

It is the same wiring diagram that is supplied with all of the controllers. I have several copies in fact, the 668, 668-401, 668-601, 668-430.....I even have a technician's furnace installation manual that also explains in a little more detail how to wire the 668 series of controllers. The only difference between the one supplied by White-Rodgers and the Tech manual is that the Tech manual shows the wire colors too. Except...I don't have any yellow wires. I've got, coming from the high-limit thermostat a blue, red and black in the controller junction box I have two black coming from the ignition transformer, one black and white wire from the motor. On the controller itself I have one white one black and one orange like in the instructions.

In fact. My blower motor and fan/limit switch go into a separate junction box.

Basically, if I follow the diagram in the installation manual for a Lo-Boy furnace which is what I have then this is how it should look. The color of the wires in the picture are exactly what I'm working with on my furnace. Most of the wires are black. Which, I don't understand. Perhaps, what I should do is buy some BX and re-run the wires from the blower motor to the junction box. Maybe this wouldn't be so frickin' confusing then.

Confirmed this morning that my furnace controller is wired correctly via an HVAC tech I ran into, that I didn't even know, at Dunkin' Donuts this morning. The diagram I posted is correct.
