Hello Hearth
I've recently come into possession of a Quadrafire Mt Vernon AE Pellet Stove that was purchased in 2007. The pellet stove has been operating fairly normally for the last three weeks, with an occasional `Vaccum Sw Error`. I've cleaned the entire pellet stove top to bottom, and read the entire manual front to back to better grasp how it functions.
This past weekend the ignitor stopped working, pellets drop and the blower is working, but no heat comes from the ignitor. I've never owned a pellet stove before so I am still learning a lot about how they function, however I am an engineer by trade so I know enough to understand how to debug mechanical hardware. Here is a photo of the original burnt ignitor.
After narrowing it down to the ignitor I found a spare that was purchased in January 2020 by the original owners. Replacing the ignitor with the new one immediately remedied the issue, and I saw the new ignitor turn cherry red within 60 seconds after Autoclean ran. 24 hours later the new ignitor stopped working. Everything else seems to be exactly as it was, except I noticed a small white burn on the ends of the new ignitor where the metal meets the insulation. Here is a photo of what that looks like. At a glance it seems like this ignitor is made of cheaper materials than the original SRV7000-462 model.
Thinking it was just a bad ignitor, I went and picked up a spare one just in case. After installing it and trying to go through startup for 10-15 minutes, the new ignitor was also not working. (New ignitor was Part #SRV7000-462)
Thinking a fuse might have blown, I removed the control board and inspected the traces to look for any damage on the PCB. It seems someone already added an inline fuse for the ignitor with a ceramic fuse, but it appears to be in perfect working order. The only possible sign of damage of any kind on the control board is the Neutral Line, which seems a bit more brown than the other components, as if it is heating up more than it should. It looks pretty similar to this photo another user has posted on this forum. (This isn't my photo but is a good representation of what I mean.)
Here is some information about my control board with the added fuse on the bottom. Apologies for the picture quality. The white plug all the way in the bottom left corner of the panel is the one that appears slightly burnt.
I am going to call a technician to come take a look at it. The board lights up, all the LEDs appear as one would expect, and otherwise the stove is operational and without error. I am worried I am going to be told I need to replace the entire control board, but I was hoping someone here might be able to advise me on another solution. I unfortunately don't have another solution at this time, and with the temperatures so low this year, I'd like to figure this out ASAP.
Also is it safe to light a fire manually in the Mt Vernon AE without the ignitor functioning?
Thank you
