    Tc, I've tried rebooting/recalibrating it. I just switched lambda sensors and it is just a plug, so I dont know how to switch the wires.

    Have you tried removing the sensor and testing with propane, you could also watch the damper position bars on the screen to see if they correlate to the the actual damper positions. Have you checked the opening in the door that the primary air pulls through, it seems to me like something is not right with the primary air delivery.

    I'm reluctant to check the sensor with a torch. I guess I can put the old one back in. I assume you mean to do this with no fire? I haven't checked the primary/secondary dampers yet. I have to wait till I dont have a fire. Its supposed to get up to 40* tomorrow so I'll be able to clean and check a few more things

    Look, I know I don’t have a Effecta, but I’ve been dealing with my own o2 sensors for years, Bosch suggested to me this method, it also burns the crud from it. These things run cherry red in a auto exhaust system. If you doubt me try it with your old sensor.

    I dont think I can do it without a fire going. The boiler has to get up to 100*c before the 02 sensor starts reading. I wish I had confirmation on this.

    That could put a damper on things, it just would be nice to see the control panel co2 percent drive the primary damper, confirming its working as it should.

    Let's see if effecta responds. If they dont I might have to try this.

    The boiler needs to get to 100c before the sensor starts reading?

    Are you sure? It should be ramping down before that, shouldnt it? That's a pretty hot boiler temp.

    Maple1, it may be reading, but there is no 02 value shown on the screen until the flue temp reaches 100*c. So I would need a fire to check it like TC suggested.

    I'm over my head here but can you unplug the wires from the installed o2 sensor, plug them onto the uninstalled one, the start a fire and do the torch thing?

    Just got a chance to watch your video - my fan is definitely not that noisy and I do not recall my 35kw being that noisy (mine was about that same vintage). Assuming you tried the basics: remove the fan, cleaned it, make sure everything is tight on it, etc. There is an impeller impeller between the boiler and the fan motor - any chance the shroud around it got bent and is hitting the fan blade? Tarm USA has a big inventory of spare parts, I imagine they have a fan for you (keep in mind that your is probably the 50 hz version - not sure it matters but make sure Tarm is aware of that. If they do not have it in stock, they were awesome at getting something for me out of Sweden.

    John, do you remember if you used a step up converter to wire up your old 35? Or, do you remember how it was wired? The way I have mine wired I use a step up to convert 110 to 220. I was told that this is how I had to wire it. I never understood why I couldn't just run 220 to the stove.

    This fan has always made this noise from day 1. I've never thought it was wired right, but the stove has performed good until the last couple weeks.

    I am in contact with tarm and waiting to hear back from them. They dont know much about my model bc they just started selling effectas.

    Maple1, that is a very good idea. I just might try that! Thanks!

    I used a Step Up as well, don't recall why it was setup that way (thought buying a step up was a lot cheaper than running 220 to where my boiler is. If the fan always made that noise then would guess that is not the issue. I am sure that between Tarm and Effecta they will help you get to a resolution. My gut keeps telling me it is a fuel issue - when I was having my bridging problems my moisture meter was reading same as yours. I was insisting it was not a wood issue. The next season I had "dry" wood and was in business. At the end of the season I ran low on wood, bought some Split/"dry" wood, moisture meter said dry - the Effecta told me otherwise. Not saying it is the fuel, I just don't know what else to suggest to you. Good luck.

    While you can clean a sensor that way , the idea was to watch the reaction of the sensor/ electronics / damper while you induced a reaction with the propane

    This is the fan running outside of the boiler. It doesn't make any noise. And it seems to be running faster.

    Sounds quieter than when you had it inside but tough to tell via video. Can't imagine it is running faster unless there has been a change in the electricity being delivered to it (it does run a little faster than designed because you are running 60hz through a 50hz motor but that has been the case since day 1 - same here when I had the 35kw).

    Ok, went through and cleaned the boiler. Took a wire and made sure every hole was open in the secondary air of the bottom of the fire box. I took the cover off to expose the damper doors to make sure they are working and as far as I can tell they are working correctly. Ran the brush down the tubes. Shook out the turbulators.

    Started another fire and no change.

    I was in contact with tarm last week asking questions and looking for some suggestions. Still no word back.

    How about your flue after the boiler?

    Hmm, yes, a plugged cap might mess something up. Although not sure that would happen with such a clean burner. Fly ash can settle out in a horizontal section too though.

    I checked my horizontal section last week and it was pretty clean. I haven't checked the vertical section though. That is on the list. Good suggestion.

    I'm doubtful, since it's a pretty clean burner - would just be something to check off the list. I haven't touched my chimney since summer of 2012. My stove pipe section does get fly ash settling out though.

    My bet, it’s a moderately plugged cap

    Or if there’s a t-y cleanout plugged or restricted?
