•Exhaust sensing technology constantly monitors and adjusts heat levels
So the change in resistance from the thermocouple adjusts the feed motor and somewhere you have a ground fault.
Soooo, ESP or the circuit board is my guess. Ask me how I know... the Quadrafire, Harman pellet stoves, DVC and now the Super Magnum all have (I suspect) the same circuitry. Harman has a policy of continuous improvement
, errm, I mean even though this part of the circuit has been suspect for 10 years, keep pushing out the same ol' crap year after year but make the stoves look prettier.Detroit has done this for 40 years and is still getting away with it.
Check the posts on DVC 500. As you have a new stove you need the get it fixed under warranty but look over the techs shoulder as he fixes it as you will revisit that again. It's a simple fix to replace the probe and I always have one on hand just in case. Keep posting on this one as we are all interested.
You suspect the dealer does not give a c rap ... very perceptive of you. I would bet even money that the stove does not actually get fixed Monday but I wish you well. I believe the problem lies in the fact that Harman does not really fully recompense the dealers for this type of activity (if you believe the info I squeezed out of my local dealer) so just give you a new stove... dream on.
