PJ, I did... it would be orange if it's connected. That brown/white wire looking thing is actually a silver screw driver. But you're saying it should also be close to the ground terminal above?

The spark only jumps a very short distance so you need provide a very small gap from that terminal to ground. It's just like a spark plug on a lawnmower or car. The spark gap is very short.

So simply tapping the ignition terminal with a screw driver won't do anything? Well, I don't know if I'm doing it correclty but there doesn't seem to be any reaction. It's also difficult to have the metal part of the screw driver touch the orange ignition terminal and at the same time get it close to the ground terminal. Because to do that you would have to hold the screwdriver vertically and parallel to the ignition terminal, but if you look closely at the picture, the ignition terminal has a plastic housing around it, so when you hold the screwdriver vertically, I don't think the screwdriver is actually touching the terminal, it's touching the plastic.

Then turn the screwdriver 90 degrees, touch it to ground and watch for the spark to the terminal. Feel free to improvise.

PJ, I've put the screwdriver on the ground terminal above as well. No reaction. Or, how long are we suppose to wait for a spark?

Once the draft inducer starts..... the spark should follow in several seconds.

Back in post 26 I left you a link to the manual. Be sure to download it as it has all this troubleshooting stuff in it.

Will report back after I try new module.

Don't know if I'm doing the screwdriver test correctly, but I'm not getting any spark. I've touched it every way possible with the screw driver. Will give new module a try.

Hey Guys!

So it turns out that it was a bad module. Trying the Honeywell this time, maybe a different brand will give me better luck, longer than 10 months! Then again, when the guy swapped out my module 10 months ago, it didn't look like a brand new part. It was used and he was troubleshooting, it worked so I asked him to leave it. Only lasted 10 months.

Anyway, even though my furnace is up and running. I'm paranoid that if I did anything wrong then it will just stop again sooner than later. So please address these concerns I have:

1. There wasn't instruction on the green ground wire, so I simply copied how it was set-up on the Robertshaw, which is put the wire in the screw then connect it to the ground.

2. The sense terminal had a jumper cable from the board connected to it. I removed it from the terminal end, so my flame sense white cable can connect to it. Does it matter if I leave this black jumper cable dangling?

3. The ignition and flame sensor wiring concern me. I guess they were like that before, but should they be wired better? How come those burners don't eat away at the wires?

They tell you to cut the black jumper off if not needed. If you don't want to cut it off.... at least tape it off as it's still active.

That ground jumper looks ok.

The spark and sensor wiring is high heat type wire. It can withstand a lot of heat but keep it out of the flames.

Okay, tape it off! I'll use electric tape. Thank you for all your help PJ! Though I only had to change the module, learning about the pilot assembly will be helpful down the line. I'm sure I'll need to replace them one day.
