    I bought this stove used in October since then the stove shut itself off about 5 times. It's always been about the first 5 minutes when the start up before the blower motor comes on. I push the on button again it start up fine for the duration.

    Any ideas?

    What "code" is it throwing? Does the board have any #'s in it? Or have you looked?

    If not? Look to see. But it may not be reaching "temp"? In the allotted time period?

    Are you sure the green "On" light is lit after pressing the On button? Sounds like a weird question, but I have had times when I hit the On button, and the combustion blower starts, but the green On light doesn't come on....stove shuts off unless I notice it. If I hit the On button immediately, the green light does come on & stove continues to start up normally.

    It shuts off completely as if you pulled the plug. I hit the On button again then it runs fine until I shut it off. It only does it at start up during the first 5 minutes.

    the 3 buttons are 4,4,1 in mode D. I've also had it in 6,4,1 it still does the same thing.

    Before I shut it down 1/2 hour before I put it into 1,3 for the feed, and blower.

    Is it shutting off after you have pellets burning in the pot? Is it always the same amount of time before it shuts off?

    Yes, it's always after the pellet is burning between 1-5 minutes after the ignition

    Try setting blower and heat at 5-5 before pushing start button.

    Sounds like the POF isnt met.

    Check the "White wire" in the back of the stove. Make sure its plugged into the board properly and its connected to where it needs to go (some go to combustion blower, some to firebox wall, etc. Depends on model).

    Also, try strating on a higher setting and cleaning the stove and vent. Ash acts as a good insulator and will prohibit the sensor from seeing the temp, in the allotted time.

    I think that the shutdown may be too early for POF to be the issue and also, my PDVC gives an "E" code if ignition fails.
    Is the "air on temp" set to 1? This is required.
    Have you tried a complete reset of the control board?

    That isn't necessary....the stove automatically starts on 5-5 when you press the On button.

    As for the AOT setting having to be on 1, his is (see post #8 above). It should still start-up even if it was on another setting....I've tried it and it still starts up.

    The control board hard reset might help.

    May have nothing to do with this particular problem; I don't know exact time interval but I would occasionally get a startup/shutdown when not presetting to 5-5.

    I don't think is the white wire. The stove have been running for 48 hours now. It is only when starting up when stove is cold.

    I've also reset the control board. It doesn't dot it all the time.

    I've been watching this post for a bit as I have a 25 PDVC stove. I am wondering if you have a fault on the POF line, if the stove is not getting up to temp in the pre-set time, the stove will shut down. Mine takes about 5 - 10 mins (depending on heat setting) to get to 150F at which point the room blower kicks in. I've also noticed that mine does not run at 5 - 5 on startup, it runs on whatever I have set the heat / blower settings for the 20 mins start cycle. Not sure if this is a new thing with this stove based on what I have read here, my stoves manufacture date being 5/12 and seems to be running different to others that have the same stove that is older than mine.

    My stove is a 2004 model.

    I don't use the igniter, I manually start the stove. It shuts off before the convection motor kicks in. I have also use the igniter as well it would also shuts off before the convection motor kicks in.

    The stove starts at 5-5 regardless of what you have it set for. It will not show 5-5 in the display UNLESS that's what you have it set to.

    You could have the display set to 1-1, and that's what shows up in the display, but when it's in start-up mode, the stove is running at 5-5.

    Well, I don't want to pop / burst your bubble here, but, when I have it set to 6 for heat and 3 or 4 for the room blower, the stove gets fed at that heat setting (I have done some timings with the amount of fuel dropped for each heat setting), and as soon as the temp gets to 150F the room blower will come on, I know it's not running at 5 as it's too quiet for it to be 5, I know this as I have tested and played with it to see, even with the higher blower speed settings set, I can hear the differance with the sound / speed compared to setting 5 for the room blower as soon as it kicks in.

    Cladmaster, from the online manual:"Automatic Start-Up
    When the “ON” button is pressed from a cold start, the unit is in “Start-Up” (after 3 seconds, there
    will be an “S U” in the Heat Range and Blower Speed windows to verify this). While in this mode,
    the unit has a preset heat range and will remain in this mode for 20 minutes to prevent the unit
    from over-firing. During this start-up period you can set the Control Board at the setting you
    desire; after the start-up is complete, the unit will operate at the user setting."

    Don't bother h20child....Cladmaster is an expert on these stoves....the owners manual means nothing.

    One can become confused by the fact that the RPM's of these motors is not precise. I don't know exactly what his timings measured, but I will give him the benefit of believing that his statements are based on observation. That being said, I think he is wrong... and Hey, he says he's no expert!
    We could all benefit from reading the owners manual occasionally.
    All of this aside, did the OP get his problem solved?
    I am sure it isn't a POF failure, because that causes an E code on the display.
    I have never seen an over-fire condition, so I don't know what the control system response to that would be. I am not suggesting that it actually over-fired in the first five minutes, I am suggesting that the snap switch might be flaky. Those switches are notoriously unreliable, and should never be designed into a safety function.
    The reason I am thinking it's the snap switch, is that the problem occurs when there is a change in temperature happening. That is when snap switches squirm and make intermittent contact.
    Just some thoughts I had on the problem.

    And who is to say that the manual is correct / incorrect, poorly written, not updated and so on ?

    I've played around long enough to know what my stove does and does not do with the settings, but it does not mean that all stoves (25 PDVC) work the same way as mine seems to. As it's been reported here on this forum many times, not every stove has the same settings from one year to the next.

    As for your comment ..... 'Cladmaster is an expert on these stoves....the owners manual means nothing.'

    No, not these stoves, just my own stove and how it WORKS.

    As for the stove working 5 - 5 at start up by default ........ show me where in the manual that the stove defaults to this setting ? By the way, notice the bit below ....... the word 'should' !

    Page 13 .......
    Subsequent Cold Starts: In a cold start situation, the unit should be operated at a “5” setting
    until the room air blower begins to operate.

    Yep, Englander doesn't know how it's stoves operate, although this quote from Mike H, Senior Tech there seems to clear things up:

    "the unit does not "adjust itself" to a 5-5 setting , the cold start procedure is actually a "leftover" from the old manual start procedure that predated the autostart units.

    The unit when the on button is pressed goes through a predetermined sequence that is not altered in any way by the heat setting, the preselected heat range will be what the unit will run at when it comes out of "startup' (S-U) after the 20 minute autostart sequence. it does not matter what settings you select to run the stove at during a cold start in actuality"

    But, maybe Mike doesn't know what he's talking about either.
