I have an Invincible T 1993 worked perfect until last weekend. I'm on a search for a Circuit Board and Enhancement board which Harman stop making 3 or 4 years ago. I've been calling dealers all over NJ and PA. Also, tried Harman they cannot help either. Does anyone have one? or know who may?
 
I do know of a dealer that has two Enhancements cards. If you need a control board these cards will do you no good.

This dealer was looking through inventory and found them.

Does Brunner's Bits and Pieces rebuild these boards? Or can you not get the replacement parts too? The place on E-Bay that trouble shoots and reworks CB's. Just a thought. Bioburner knows about these guys that will recondition boards. He might have a suggestion but not sure on the Invincibles. Hope you all can come up with a solution. I think those are cool old stoves.

I got my board for my 93 Invincible T rebuilt by Brunners last year. I think it was around $100 plus shipping. It took about 2 weeks and has been running great ever since.

Thanks everyone, I have a friend that is an electrical engineer he actually builds custom boards for defunct pinball machines among other things - he has them now and says they can be saved. They seem to always fail at the two hot pins where the boards first meet the 120V. He found a replacement pin set and is going to solder an additional "runway" to support the area. We shall see.. I'll be getting this back in a couple weeks I'll report back. I'd be wise to buy one of the enhancement boards if I can. It might be worth it to just it as it took the brunt of the damage. MSmith66 would you be willing to share the information :) I'm in Central NY as well. 607-432-0186.

I think mine shorted at the same spot as yours. Brunners seemed to be familiar with the fault, and said that after their repair it shouldn't happen again since they used superior components.
 
I have been trying to message you but I'm not sure if it went through can you pass along the information where that enhancement for it might be made available to me. that seems to be the part that was supposed to affected by the injury it would be great to have one on hand

Sorry, I have been very busy. Send me a PM with phone # and we will talk about the board more.
Thank you.
 
Ok update, got the board repaired and it looked good. Plugged it all in and nothing. The tiniest sign of life can occur when I pull the fuse out and back in. When I do that the feed motor runs for 1/5 of a second sometimes. Other than that no sounds and no lights. He said to give it back to him with the wiring diagram. Not sure what if anything is next for the "Invincible"... Any feedback appreciated.

Did you happen to call the dealer we talked about for another Enhancement board?
 
I just went through this with my Invincible T. I ended up bypassing that worthless connector entirely and jumpered around all of it using stout wire and proper connections. I also reverse-engineered the "Enhancement" board because the feeder motor would make all kinds of weird noises when the stove was off and plugged in - turns out all it does is cycle the feed motor as long as the exhaust blower motor is on. I added a small Resistor/Capacitor snubber in there and the problem went away.

As long as you're selling parts, tell me what you want for the distribution blower and the burnt-out circuit boards, although listing it on ebay for local pickup only will probably be a better bet.
