    Hello
    Just came across this older Tasman 40 and the electrical cord was cut off! So I plugged in a new line cord and turned it on. The Igniter does not get hot but the exhaust fan works and even though the membrane is in tough shape, the control panel seems to work fine!
    I am impressed to see a newer better designed door latch and a re-orientated Convection blower where the motor is on the side instead of on top of the squirrel cage for longer life!
    So what is wrong? Have you seen this?

    No the auger is turning and not working very well. The video shows what is wrong.

    Looks like more things turning in there than should be? Rust does not help much either.

    Bingo!
    The Brass bearing turns with the auger!
    The turning of the bearing with the auger will cause erratic pellet feeding and possible jamming!
    The heat dries out the impregnated lubricant and then gets dirty and sometimes black from the pellets inside.
    Then sometimes as in this case, the auger bearing sticks to the auger and when the bearing turns it rips and gouges the outside of the bearing and needs to be replaced. This stove has a 3/4” diameter auger and can be upgraded to Nylatron! Also one thing I learned is that cheaping out and just enlarging the hole in the original end plate is a big No-No!! The new end plate that comes with the Nylatron bearing must be drilled to the Tasman 40 hole pattern and be installed! This is the only way to do it right!

    Hello
    More problems with this pellet stove. Looks like the previous owner tried to get the auger motor off. There is no auger motor set collar. The base of the auger shaft has a threaded hole. Someone put a torx bit in the set screw and broke the bit off in the set screw! What a mess. I took it to my friend and he drilled it all out, retapped the threads and put in a new set screw! Bingo this wood pellet stove is no longer junk!
    It can be fixed!

    Pic 1 - Auger with Broken bit inside set screw!
    Pic 2 - Auger retapped with new set screw!
    Pic 3-4 Inside Of Auger Bearing and base of auger so nasty dirty! No wonder the bearing turned in the end plate!
    Pic 5 - Shows quite a bit of Auger Pox too!
