    Hi Folks, any suggestions here? Today I gave my Harman XXV a complete cleaning. The basic clean out: scraping pot, brushing ash, vacuum, and then the full clean: Brushed out the vent pipe/exhaust, removed the back cover and vacuumed and brushed the fan( that is a pain in the but to get to) and than the other side I cleaned out the box that gets the pellet fines. After putting everything back and turning the stove I'm getting nothing for heat. It's blowing no more than 250 degrees from the blower and that with the fan on high and the temp dial cranked all the way up. Ive tried it both on room temp and stove temp getting the same results.

    Maybe a wire is disconnected or try cleaning it again

    Hey Donn, did that cleaning include the combustion fan and flue area, ESP probe and tee clean out? In other words a complete exhaust path deep clean?

    Yes it was deep clean. I'm wondering if something happened when I pulled the fan out with a wire

    Hmm...how dirty was it? I am wondering if it just seems cooler now due to the exhaust path venting better. The flame look good? Is the convection blower running?

    :: edit :: 250 coming out of the convection air sounds good

    You didn't whack the ESP, did you?

    I don't think I touched the ESP at all. I've never done anything with it it's coiled up in the back. Seems to get a good a reading like that.

    It
    was pretty dirty. I use a cheap Ryobi laser temp gun I bought at Home Depot to locate drafts in the house to get a temp reading from the blowing air. It's usually reading over 400. The flame looks small and way at the back of the burn pot.

    I am confused. You did a complete clean but didn't remove and clean the esp? How did you ensure the back end of the exhaust flue was clean?

    You're referring to the Room temp sensing probe. The ESP is in the exhaust path in the stove. Not sure exactly where it is on the XXV.

    Ha ha ha now I'm confused. Where is the ESP I've always thought that was the coiled up wire. As far as the back of the stove I just removed the fan and the cover on the other side

    Now I know where it is. It looks for me to get to that are I would need to remove venting which makes me a little nervous. Now is it possible with me using a vent brush cleaning out the exhaust from outside the house I could have harmed something?

    What is your vent configuration? If your vent goes strait out P38X2 may be right. You might have damaged the ESP. Also may have packed some ash into exhaust flue.

    You guys know a lot more about pellet stoves, I have only been in the game about 6 weeks, and I do not know your stove but I did not seat my ash pan quite correctly and it was letting in a draft from below and damned if I could not get the stove above 220 degrees at whatever setting I tried. I discovered it on the clean out I did not long after, and right back to burning hot. I was very relieved.

    Is that room sensor supposed to be coiled up like that.

    Ya. It looks like you could have made the bend with your brush and hit the ESP. It's also possible that ash got pushed over that downward turn and piled up at the bottom. You could try the leaf blower method to clean that out. You can get at the ESP by removing the left panel. It is located on top of the exhaust flue right behind the flange. You could at least pull to out (gently) to make sure it's not bent and give it a clean while your there.

    Ya, I don't know where the ESP is in relation to the back of the stove...if that makes sense. I gotta assume it's in relatively the same location when looking in the exhaust outlet from the rear of the stove. If that's the case, it would be VERY easy to hit it with a brush coming in from the termination, particularly if yer vent is a short straight shot.

    Ya it's possible you called it. It not far away from where the vent collar meets the flange. About 3-4 " in. Donn will need to pull it out and give it a look over. The other immediate possibility is that area is packed with ash.

    I think that's the OEM spot. I ran mine like that for several months. Worked fine. I've since uncoiled it and hid it stealthily. I don't think it made a bit of difference. Of course, YMMV. If it's tucked UNDER the rear panel, I'd imagine that'd be no good.

    I have a corner install also. It's just below the hopper height so we can't see it
