Appreciate you posting that picture. While the 1/4" difference on the outside dimensions may have slipped past my analytical mind :) , I doubt I would have Not noticed the difference in the intake slots between the top/bottom and left/right......of course I did basically admit I knew nothing about this!

Logic says this must be a draft problem related to a blockage or gasket issue (to McGovern point). I was convinced imhad all that covered. Maybe this flue gasket isthenissue.. With that in mind, I'll be happy to discover the solution, hopeful I can put back in the old control board and pressure switch and if they work, happier then heck to return $600 of parts! (dealer says they do that for me)

I'm going to pull the unit apart again tomorrow. Thx for that one.

Yes, the intake slots are different sizes. In October, I almost installed it wrong myself, but noticed the gasket was not lining up with the slots in the Flue. I thought I had the wrong gasket, until I turned it 90 degrees, and it lined up right. :doh: :crazy:

Ok before I explain let me first thank all of you for sticking with me on this. As a group we covered nearly every aspect of a DVC500 and we probably know it better then some of the dealers out there. A special thanks to 009to090, Coalnewbie and McGiever for your public support and private messages on this subject and Big Jam for a great second set of eyes....

Recap:
Oct 26 I post that on first light the things not burning right and I explain what Im finding. I went thru a alot of guess work, spent tons of unnecessary money and wasted loads of time. That problem was either one of the probes or either the combustion or draft motors as after I replaced all of that, the fire lit perfectly but then I got the dreaded 2 blink code and Ive been fighting that one for weeks.

During the battle to overcome the original problem I bought a control board. That board only worked with a new pressure switch, combined $650 bill. When I got the 2 blink code, I decided to go ahead and get the new pressure switch with the board. The code indicates a loss of negative pressure in the firebox and everyone including the dealer that befriended me in PA suggested the same.

fast forward to last week:
I get the switch, put it plus new board back in and no luck. Still the 2 blink code.
I get into it with Harman tech whose being very logical about this but I am adamant when I state I have checked every gasket, every cover, door and the pressure hose and filter. He's going to get me a regional manager

Friday, 009to090 suggest I look back into the flue pipe gaskets, they are not symmetrical and could be in wrong. I argue it but Ok, could be Interesting.

Yesterday:
I get my friend on the block (hand fire coal guy and member here; Big Jam) to come down and put another pair of eyes on this. Hand fire guy is aching to find a reason to make fun of me so here we go. We take the unit off the flue pipe and sure as s#*% the gasket is in wrong. I take the 45degree elbow out and the 2nd gasket is wrong. An improperly installed gasket might restrict the intake slightly, I cant see this as being the culprit. The gasket still seperates intake and exhaust in either position. While Im scratching my balding head over that I am retracing all of the work I have done for Big Jam to comment on. I have the doghouse off the stove, pulling on wires and tubes when suddenly the problem reveals itself !

Apparently, after installing the new motors and probes many weeks ago, checking all wires and tubes and reassembling, i failed to notice the pressure tube was PINCHED closed as it passed thru the back wall of the stove with all the wires !!! Thus I have had the 2 blink code since putting in the motors. SO EMBARRASSING.

Reassembled it all with the tube freed up; new switch and board and it works perfectly. Ran it all day Saturday.
Decided I never needed the board or switch so this morning (24F outside, 75F in) I shut down, put back in the original board and original pressure switch, its been running all day now! Confirmed. The dealer said they'd take back what I didn't need so that's my final act and Im done! I did also replace the front door glass and now once and for all, heating harmony has been restored!

Thank you to the forum and all members here. Without a reliable dealer and without knowledgeable service resources in my area, I needed this team to get me going again and you did it.

HAPPY HOLIDAYS TO EVERYONE !

Not that you wanted to go through all of that and the added cost but, yourself and many others running the DVC500 now have much more knowledge on what makes that model tick. Your issue is a prime example of everyone pulling together to help a fellow member out, and this is what makes this such a great place. Good to see you got it figured out. Now you can stay warm!!

Good deal man! 8-) A testament to your patience. I'd have been on Saturday Coffee posting pics of the slug holes through the new DVC-500 target outside. :D


Also I can't tell you how many times I've searched the net for info on a problem with a specific vehicle or machine, and you read through 5 pages of BS ...... and they leave you hanging! Nobody ever follows up. Another great thing about this forum. This one will help a ton of people out & save them a bunch of cash. 8-)


I still don't like electronics ....

All in less than 15 pages...
You got the cash back for parts...
And learned a valuable lesson...
The most basic cause of the problem is often dismissed...
That second set of eyes is often invaluable...
Glad it all worked out in the end...
Thank the folks at Harman that helped you...
And keep those phone numbers...

Outside temp, 18f
Inside temp, 72f
Working well.....

Yep... Lots of lessons learned in the one. The funny thing is I've been here before on other projects ;) and along the way here I had a feeling it would be something simple and probably self induced! .... so will I remember these lessons next time? Isn't that the trick!

Once again, huge shout out to Dave and team at Hoffman Stove in Hallifax PA. Great patience, connection to Hoffman, customer service, stock and pricing. He didn't sell me the stove but he treated me like a long time customer.

I'll send back these parts, he still got a better then $600 sell, lifetime customer and I'll never stop recomending them.
(To my selling dealer (KR), if you are still lurking here, take note what good consistent customer service looks like and the payoff)

Thx again team

Ok, full credit issued to my CC for the control board and pressure switch. Hoffman continues to impress.

Been a few days and all is well. Oil heat is off and the house is hot. Thanks again everyone and happy holidays.

Enjoy the Coal Warmth! glad it all worked out, now you should be set for another 4 years of uninterrupted DVC500 burns(burning?).
Did you save the old motors and try to clean them up any? Maybe make good spares?

Hoping you are right there!

The draft motor was destroyed trying to cut out the fan blade. The combustion motor I have and will save but no idea if its good or not. Draft motor was ok to begin with
