    I recently purchased an Englander summer's heat stove back in December. Model # 25-pvdc/55-shp10. It has been working great up until yesterday when I started to get an intermittent noise coming from the exhaust blower area. Just wondering if anyone has experienced this or not. It's hard to describe it, but it just started a day or so ago. It seems to be still exhausting the air just fine and everything as of this point still seems to operating correctly. I will call englander tomorrow, just wondering if there was a quick fix for this right away. Hope that maybe it will just be a cleaning and hopefully the motor is not going bad.

    The other issue I was hoping to have someone answer is the rate of pellets that are used. I've read from other posts that you can reduce the amount of pellets used on the 1 heat range setting. When it gets into the upper 30's and lower 40's (farinheit), running the stove at 1 is even too warm. And I'm using pellets that aren't needed. Can anyone tell me the procedure to reduce this rate? What are the settings that I need to set? Thanks, Mike.

    Small noises from pellets stoves can simply be harmonics - a good way to test for this is to hold your hand on certain parts of the stove when the noise happens and see if it stops. If the blower is easily accessible, then you can even try holding your hand on the blower housing. If it stops, chances are that your problem can be solved by tightening the blower mounting screws or similar actions.

    Does not sound like a cleaning issue.

    Craig's given you some good advice. If holding your hand on various places doesn't seem to change the sound then take a close look at the end of your lower auger tube. Carbon can build up in the end of it and cause a noise similar to what you are describing.

    I get a lovely humming noise out of my exhaust blower from time to time. It'll pop up and humm (somewhat high pitched) for 15 seconds to a minute, and then go away. 1/2 hr later, it'll come back again. Just yesterday, it was fairly constant. I squirted just a little teeny bit of WD40 in the back of the motor and it shut up. Note that this noise didn't start happening until I cleaned the exhaust motor, which required removing and reinstalling the fastner nuts around the motor flange... So, like Craig said, this is probably due to something needing to be more tight or a little looser, or maybe just it was gummed up and needed a little squirt of the fix-it juice.

    My wife says that the noise doesn't bother her - that she hardly notices it. To me, it's so loud I cannot stand it! She also said that the leak under the kitchen sink was "just a small leak". Heh.

    Thanks for the reply, but it's not an issue of anything being loose. I tried putting pressure on all the areas around the fan and housing.

    ElPedro, I think what you're describing is what I'm experiencing. However, I've only had my stove for about a month and I've never had anything internally apart. I'm just hoping I don't have a failure about to happen. Thanks, Mike.

    Any resolution to this problem? I am also starting to get a regular noise from the blower. Started a week or so ago. It is hard to describe but it sounds like metal on metal at high speed. Maybe a bent fin rubbing something? The pitch changes with the blower speed. No way we can live with it.

    Looks like I 'll need to start pulling parts off to figure it out but I would appreciate any shortcuts.

    if the pitch of your noise changes when you change the "blower speed" the issue is in the room fan, if the unit has been in use for a season or more it could be buildup (dust bunnies) so to speak , that fan tends to attract them , this can change the balance of the squirrell cage and cause vibration or even in an extreme case a rub, let me know if you are still fighting this after checking that fan , shouldnt even need to pull it to check it

    sounds like a singing blade, ive seen a few of these over last couple years , doesnt cause a problem with function most times, as web said , its a harmonic , but an internal one to the blower. as for the slowing down the feed rates , let me know how long a 40 lb bag lasts you on its lowest heat range and i will give you some settings to dial it down.

    The sound finally quit after about 5 days. Is there any way to fix this in the future if it should happen again? I am relieved to know that the motor was not dying! I did finally make contact with someone there at Englander. I have the "low fuel feed" down to 4 and the "low burn air" up to 9 because the stove wasn't burning the pellets thoroughly. But it is now with these settings that englander gave me. With the restrictor plate all the way to the back of the stove and the low fuel feed on 4, I am now getting about 20.5 hours on a 40 Lb bag. Would like to get it to 24 hours but I don't want to risk having the fire go out. Mike.

    you could try lowering the low fuel feed to 3 and lowering the low burn air a notch or two, this would bring in less fuel and still should get enough air to burn without burning it too fast. just remember where you have it now and you can go back to it if it looks like it will starve out

    Yup, yup. Sorry I didn't read the original post carefully enough. It is the room air fan that I am talking about - not the exhaust. I've only had the stove about a month and even with my wife's housekeeping, I don't think it could have sucked up too much dust already. I call your place or post if I can't figure it out.
    Thanks
